@soundsnags2001 the drop safety issue came down to the weight of the original trigger, they swapped it out and the drip safety issue was fixed (in 2017). The MSAFET toolkit does add the extra level of piece of mind for some, but to me this gives your p320 a new level of modification, I like having the OPTION to have the MS or non-MS model. Here’s a link to the kit, if you scroll down it also has a link to the updated and complete “how-to” video: sigmech.store/products/msafe-t-p320-manual-safety-conversion-kit
Love the video, thank you! I already sent my FCu and had it modified. I purchased the Wmanual safety parts kit and now just need to intall it. I am old school and do not entirely trust any striker fire to not be able t have a misfire. I have seen glocks and just about every one of them have a murphy law day and go off. where a simple manual safety fixes or at least greatly reduces that to almost a 1 in a billion chance. I know many striker fire enthusiast will argue it slows your response time yadda yadda, all made up excused. I lift the safety on the draw after it clears the holser in and out of copetition and it has never ever effected my time.
No idea why Sig would not make the FCU the same for the Safety and Non-Safety versions. Seems like more work for them. The P365 you can just buy the Safety lever parts and they fit right in to the FCU
I refused to buy a P320 until I could get one with a manual safety. I would be interested in a conversion kit, but I would want it installed by a gunsmith.
This will ABSOLUTELY void the warranty. However it’s something people decide to do for various reasons. There are a few companies that have offered this as a service for several years and it seems like those that opt to do this really like it! Only down side is having to ship off the gun.
In many ways, it’s strange to say it, but the reality is in every instance of modifying a firearm yourself, the fine line between “it failed on its own” and “I did it wrong” gets too blurred, if something goes wrong. It the main reason why all the part manufacturers make a note that all parts should be installed by a qualified Gunsmith. Even when it’s just swapping out a trigger, (which is a task almost all of us know how to do ourselves). It’s the unfortunate reality of liability . However, I wholeheartedly agree that if you are not going to be 100% confident in the modification, the M17 or M18 is the way to go!
I would love to see a conversion kit come out for the p320, I have a standard compact and would feel a lot better to have the safety lever installed on it
I spent my 21 years in the Marines with a manual safety on the M1911 and M9. Sometimes I still reach for the safety on my P320. I would like the option to add it to all 3 of my 320’s.
Knowing what I do about the P320, including what I learned here, I can conceive of no way that any of mine are capable of discharging on their own without the trigger being pulled either directly by finger manipulation or indirectly by the action of something else that does it. Unintentionally pulling the trigger by one of those means, especially the latter, is of course possible as countless Glock owners have discovered. Because of that possibility despite my best intentions and practices, I would definitely consider such a modification to the guns I have. I am therefore very interested in learning what would be involved.
@@SIGMECHANICS I'm with John. As a Certified Factory SIG Armorer and professional gunsmith, I wholeheartedly agree with his points above. Having said that I would like the optionality of installing manual safeties on all my P320's. When I purchased my SIG P365, I bought it with the manual safety.
YES! I'm 62 and I've been shooting guns and hunting since I was 10 years old. I only buy guns with manual safety's on them. I want the P320 X Five DH3 but they don't offer it with a Manual Safety. My P365X has a manual safety! My P226 is the SAO with a Safety. I think this idea of a Manual Safety conversion kit is a great idea! I think there are a good amount of people out here like myself that are maybe old fashioned and still prefer a manual safety!
This is one of the reasons why I made this kit. I know the manual safety is not something everyone wants and that is a debate that will go on forever, but for those people that do like it being able to have it is a game changer. Not to mention, my favourite feature is that once you do have the manual safety cut out, you get to decide at any given time if you want to switch back-and-forth.
Yes, please make this available. I have concerns with the non manual safety p320 that I have. I know the reports of it "just going off" are questionable and rare but this would give me some peace of mind. One question would be what tools are needed for the modification?
Im not one for a safety on my guns but your content is always so informative and interesting and sparks my interest. If you produced a video on how to mix cake batter with a FCU I would probably watch
Ha! Thank you, that’s very kind of you to say. I’ve been working on a bigger video project recently where I am testing every P320 trigger in existence which I hope will drop in a few weeks. It’s high in data and I think it will help everyone, but especially those who are into modding their P320. Keep your eyes open for that one! Thanks for watching and being a part of this community!
I absolutely am interested. There is an outfit in California that installs a kit but I would have to ship the fcu to them. If your kit is affordable, I'm in!
Keep in mind that even if you were to ever modify to have a manual safety on your P320, you can always switch back-and-forth between manual, safety and nonmanual safety at any time by swapping out one pin, and using a nonmanual safety grip module.
I chatted with Heath at Sig yesterday in response to the 6/14 "colorful parts" email and he says Sig is now offering a factory conversion of a P320 to add the manual safety lever for $265 including parts and a new grip module and return of your current grip module. Cost for a P365 was $160. presumably because the frame is already configured for a manual safety lever and doesn't require modification or replacement like a P320.
That’s pretty cool! I like how they constantly come with new designs to customize! My project is a bit different, here’s the updated link with the details (the project went live not long ago): th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I've been looking at various full size 45 and 10mm handguns for use as a woods gun. Although I like the Sig P320 XTen, I had pretty much decided against it because of the issues that have been reported with accidental discharge. Even after their upgrades, if you are counting on the mass of the trigger to be light enough in during a drop to not move the ~0.190 inch that is required disengage the other internal safeties, and if you're counting on never having anything snag the trigger in a holster, then I'm just not comfortable with it. Glock at least has the trigger safety. Springfield has trigger and grip safeties. And the DA/SA guns don't have this issue at all because of heavy trigger pull in DA mode and manual safeties. That being said, if you offered this manual safety, I would quite likely buy the Sig and it would certainly be upgraded with the manual safety. I think having a locked trigger would be better than trigger and grip safeties. And I like the gun other than this one critical issue.
Would love to add to mine. If you do get this into production, I would like to hear more details. I had always had a manual safety in my early years because of time in service and got use to them. Times have changed and most have chosen to go away from them. I have seen though most accidents though are not from holster pulls but from exposed triggers, that is where I believe a safety would be most helpful. If you roll this out, I could see myself making the purchase if I can find a gunsmith willing to do the work.
Thanks! It’s been a while because I’m working on a bigger project where I had to obtain every trigger that has even been in existence for the P320, but now I’m close to posting that video and I had time to make this quick “teaser”. I’m glad your enjoying the build! It’s a great platform (especially for tinkerers).
This would allow you to install a factory manual safety. Therefore, you have every benefit the factory system provides which includes preventing the sear from dropping which will prevent the striker from releasing.
It’s criminal the way Trudeau misrepresents Canada’s existing laws to the public to garner support. Canadians will have to get innovative in order to continue to enjoy their hobbies.
There’s no need to send it in. This kit could slow you to do this at home. The kit comes with everything you need , you only need to put the time in to get it done.
Obviously with the recent influx of "SIG News" this would be something worth putting out there. And after looking at other options that come with this (1911, Beretta 92 etc) I've decided to put one on at least one of my FCUs. Looking forward to it.
I carry a M18 safety off and round in the chamber, but like the fact that when doing things like unloading or loading I can pop the safety on for extra peace of mind. So I would say that if I had a striker fired weapon with no safety this mod would be something to consider.
Absolutely want this. I have a M17 issued to me by my Reserve unit and i like the ambi safety on it. My EDC is a x-series with no safety and i would love to have the option to carry it loaded with safety on instead of just loaded
By the way, this project was launched a few months back. If you want to check it out the video is here: P320 - MANUAL SAFETY FCU CONVERSION PROJECT th-cam.com/video/VOudh7JT_4w/w-d-xo.html
I would like a manual safety on a p320 to avoid a discharge when re holstering the pistol and there is an obstruction in the holster that could press the trigger. We do not always look to see if the holster is clear with no obstructions before we re holster.
The P320 kit is actually already available! See this link for the updated video with details: (UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT th-cam.com/video/wOTGWaTOrqA/w-d-xo.html The MSAFE-T Toolkit itself is available at www.sigmech.store
I'm genuinely curious, why would I want to add a safety? What are the pros? I have been a big Glock guy for years and p320's are new to me. I love them tbh. I have 3 and none have a safety. I do notice that this conversion is popular though.
There is no real pro or con, within the Sig community the aspect of modularity is huge, I believe that since it’s an upgrade that makes it so that you now have a new option to modify the gun, makes this very popular. Once you do this upgrade you can then swap back and forth between safety or no safety which I believe is a good way to not have to buy another FCU (just to have that option). It really ultimately comes to a personal preference when it comes to personal use/protection. Those with 1911 backgrounds love a safety, those with Glock experience may not even ever use it.
It actually works with Sig factory parts, here is the full how-to video (the project launched not too long ago). I should note that the kit is currently out of stock with new stock set to arrive in about a week with a few upgrades. So make sure to you subscribe to the “notify me” on the Sig Mechanics webstore to get an email when they’re back. (UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT th-cam.com/video/wOTGWaTOrqA/w-d-xo.html
It’s hard to provide rough dimensions since the location needs to be pretty specific to connect the factory parts. The kit however will give everything perfectly without guesswork.
Yes, AB is an amazing choice if you don’t want to or feel like doing the work. The kit however will allow you to have the MS without some of the hassle.
@@SIGMECHANICS sorry, I watched the video on my iPhone Mini with kids screaming in the room and sort of missed the main point :) I thought it was an option to send it to you. I'll charge my Dremel and stand by. Already have cut one module to accept the safety. THANKS
Hehe, I’ve been there! If you’re a tinkerer and enjoy the craftsmanship of working on your gun then you’re going to enjoy this… maybe wait for the kids to go to bed first though.
I had the manual safety conversion done on my P320 by AB-Protoype because the trigger is basically a single action only. I've had a lot of people disagree with that because (its a striker fired gun, not a hammer fired gun, so its not single action only and doesnt need a safety) and thats fine if you dont agree. You do you and I'll do me and I'll take the manual safety version.
I am a long time 1911 guy and would dearly love to add a thumb safety conversion to my P320 Spectre Comp Just feel like I need that additional comfort level.
There’s an update to this video here, with lots more information: P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T) th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I would love to be able to send my FCU and grip module to an armorer to have this installed. PLEASE let me know who does this🙏🏻 I have no concerns about warranty.
I actually released this project publicly a few months ago. Check out this video for more information. P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T) th-cam.com/video/zemqe3gMqJs/w-d-xo.html
Good idea. Was gonna make a couple comments, but you pretty much covered all the things I was gonna say (about the MUP-1 and companies that will add the safety cut to P320 FCU's and MUP-1 FCU's). I guess the main point would be how much is costs... and if that's worth it.
I believe you need to send both FCU and Grip and both are charged differently, or perhaps have to purchase a new grip. I would aim for half that. Plus, you would be able to possibly reuse this kit, which would be substantial if you have more than one FCU.
@@SIGMECHANICS Yeah, good point. It's nice too, because the safety cut doesn't interfere with the rest of the parts, so you can always add or remove the safety (esp if you have a non-safety cut frame, but that's just to make it look nice without the safety). Yeah, reusing it is a major bonus too. I know several people that have several P320's who want to add a safety to at-least one of them, but never have, because they just don't want to have to mail their guns. Can't blame them though, I'm the same way.
This works great on the X-Ten. Here’s the updated video with more info: P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T) th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I believe this would be a big seller. I recently had the FCU frame milled out to accept a manual safety because of continued accidental dischargeproblems with the P320
I always felt safe with the P320, but I also always understood that piece of mind with your carry is far more valuable to an operator. Even the slightest mental hesitation makes that firearm dangerous, even if it’s not. Hopefully, something like this will provide that peace of mind at what I would assume to be a very low price. So far everybody seems to be very positive with this project so I’m going to see about getting this into production soon. I just want to make sure I can provide everything down to the bits before this becomes public.
Does the m18 manual safety block the sear from releasing the striker or just the trigger from being pulled? I'm a Little nervous using the m18 as a everyday carry
The safety essentially physically blocks the trigger from moving forward, there is a pin on the safety lever that locks into a slot in the trigger, which then stops the interaction between it and the sear.
Yes! It launched about a year ago, here is the full video… let me know if you have any questions. (UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT th-cam.com/video/wOTGWaTOrqA/w-d-xo.html
I'm honestly shocked to learn Sig does not provide this option. It seems uncharacteristic of an otherwise top notch gun company that prides itself on modularity.
Part of the reason I released this project is because I wholeheartedly feel Sig should just include this in every FCU they make, it’s such a minor thing to add into production! Here’s the updated link with all the details for this project: th-cam.com/video/wOTGWaTOrqA/w-d-xo.htmlsi=i1VRUvA6qRsNL8Xn
I own the Carry AXG metal. It is my favorite pistol. However, with latest lawsuit I just won't carry. I was told it was not possible to add manual safety. Now that I see it is potentially possible, I now face the problem that my frame is stainless, which means as much as I would jump on the opportunity, it won't work with my metal frame .
I have not tested it on the AXG, although i imagine the process would work if you first remove the grips. I do intend to try it out though. I will report back once I do.
I’ve actually launched this project already! Here’s the link to the updated video: P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T) th-cam.com/video/zemqe3gMqJs/w-d-xo.html
Hello, could you upload a video installing this kit? Since there is no video of this on TH-cam, apart from that I already bought the kit in the Sig Sauer online store and it did not bring me any instructions
The complete step by step is in this video here, which is the update to the video you commented on: P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T) th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I didn't even realize the safety equipped FCUs are different. I was about to buy a safety, thinking I could just stick it in. Seems weird that they make a specific modification to the FCU for a modular design.
I was able to launch this project publicly a few months back. Here’s the updated video! P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T) th-cam.com/video/zemqe3gMqJs/w-d-xo.html
Any update on this? I would love if I could have one sent to Australia, obviously it would be a lot easier to convert it myself as opposed to trying to send an FCU overseas!
great idea! I've USED AB Prototype and their work was great - but you need to ship R/T which is costly, plus it's a cost per FCU Always wondered why Sig doesn't just cut the needed slot in ALL FCU's - and give the option of manually adding the parts later if desired
@@SIGMECHANICS I may still buy this in case I buy another P320 FCU without a manual safety. Thanks for your videos and now this incredibly innovative tool
i would be interested. would i be able to convince you to send me the dimentions and location for the pocket on the FCU for my own use? as i will not need a jig.
I can would but I don’t have it set off t that way. I also would NOT recommend to free hand it. The bits will jump and it will be hard to gauge as you go without parameters in place.
This project actually went live just 3 months back! Here’s the link to the updated video. P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T) th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I love this! It would be another way to customize FCUs, which is the whole point of their existence! I think some jigs for milling the grip (including the axg side grips) would be great too
I've seen the jigs for cutting the grip, but I thought you were supposed to remove the side panels and do them separately. Either way, it shouldn't be too hard EXCEPT that the panels need to be milled to be made flush with the safety, and I know I'm not going to be able to do that (without making it look terrible). Either way the safety conversion kit would still be awesome!
So I’ve found over trials that there is an order of operation for this to work really well, mostly it’s time investment and direction of tool travel, but even those inexperienced have made it work in testing. I hope to get a full “how to” video out soon.
@@Dante-420 it's actually really easy with the polymer grips, few minutes with a dremel and done. even if you mess up a bit, the safety itself is big enough to cover a minor error. Dunno about the AXG though - that's aluminum, whole different beast, never tried it. But aluminum is pretty soft...I think you might want a better jig, but a router should be able to mill it easy enough
Edmund - I've really enjoyed your other videos, however you really hit it out of the park with this awesome kit. I just finished adding the manual safety to my p320 X-five (original version, not the Legion version) using your kit, and am really pleased with how well it works. For me, The key to success was your "P320 Manual Safety Conversion" video here on TH-cam... Without your very well made and thorough instructions I'm not sure I could have completed the conversion successfully, but following it very closely made the process painless and straightforward. Also as a side benefit, I learned a lot more about the p320 in doing this conversion. Thank you so much for the work you put into the Kit AND the great step by step video - I have mostly shot 1911's for decades so I am used to safeties, and now my competition x5 has the same manual of arms as my 1911's and 2011's. Your Kit and your step by step video are absolutely first rate! Keep up the fabulous work!
Hi Phil! Thank you so much for your kind words and support! Since this kit is so new in the market, it’s extremely encouraging to start hearing people are not only using the kit, but also finding it a useful and educational experience. If you get the chance, I’d really like for you to leave a review/ testimonial on the ModGuns site about your experience! Thanks again Phil, if you ever need anything at all let me know!
@@SIGMECHANICS I was very happy to leave a review/testimonial on the ModGuns site - it's the very least I can do to thank you for the obviously very hard work and time you've spent on this project. By the way, I just got back from the Range about an hour ago, and really loving the newly installed Manual safety - before I went, I was a little bit concerned that the Safety levers seemed smaller than the lever's on my 1911's, but after about 20 minutes or so, I really don't notice much difference at all. They work GREAT!!! Thanks Again!
@@SIGMECHANICS I just checked the ModGuns site and I don't see my review/testimonial on it - I tried a couple times, but still don't see it yet so I sent them an email. If the testimonial doesn't show up by Monday, I'll follow up with them....
I got an email from modguns that they just reviewed and approved several reviews, so I see 4 reviews on their site now (the first 2 are mine - don't know why it was duplicated), but it looks like all the reviews have been truncated to 220 chars even though the web site allows you to input much more text. I emailed them again just to let them know as all the reviews have been truncated to 220 chars... At least there are 4 reviews on their site now.
Ah, good catch. I will let them know about those character restrictions. I do know that since the site is completely te-vamped as of a few weeks back, there are small bugs they need to clean up in the next few weeks. In any case, thanks again!
That is an older video, the MSAFE-T kit is now available to purchase. Here’s the updated video: (UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT th-cam.com/video/wOTGWaTOrqA/w-d-xo.html
I prefer to appendix carry. However, without a manual safety, I only OWB carry my p320. This product would give me the confidence I need to carry a p320 AIWB
Absolutely! I’ve done to an x-Ten (which also uses the .45 frame) with no issues. There’s an updated video with details here: (UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT th-cam.com/video/wOTGWaTOrqA/w-d-xo.html
I like pistols with a manual safety. Since Sig doesn't sell FCU with manual safety, I bought used m18 just to get the FCU. I would love to convert all my FCU to manual safety if I knew how.
Howdy Eddmen 🤠 I have a question, I have noticed by handling many p320, p365 & m17/m18 models. From what I owe to many other gun shops with new and used SIG’s. With every single manual safety m17/18 I’ve handled, I noticed a bit of sucking down movement of the rear part of the upper slide when dry firing without the magazine installed (with mag installed the movement is less because the mag follower is pushing up, but still very noticeable)… Now with all the non manual p320 & p365’s I’ve looked at, there is no perceived to very little sucking down movement with the rear upper slide when pulling the trigger with or without the mag in. When checking for slide and FCU movement/ wiggle/ relationship tolerance, it didn’t seam like the non manual safety models had much less movement/ tighter tolerances. I believe I understand that the sear moves in a downward movement when the trigger is pulled and what ever slop that is in the striker fire housing, slide and FCU gets tightened up by the friction with the sear and its downward movement. Now I was told by a sig expert that all sig models are Assembled guns vs fitted for better assemblies with tighter tolerances, even if it’s a legion model. And so one could get a gun that fits tighter or looser than another no mater the model. Which would mean all p320’s would have variation of slide movement no matter the model, and a M17 could have next to no movement and a xFive have quite a lot. Which is not my finding with the sample size of 20 I have experienced so far. So my two questions for you are. •One, do the M17/m18 models run different tolerances or parts? Like is the slide hole for the striker fire unit bigger or the striker fire housing smaller? •Two, when modifying a non-manual FCU into a manual FCU, does the movement change? Thank you for your time.
Great analysis. To start I will share this video where I talk about the slide movement and why: th-cam.com/video/itGqqq8IcL8/w-d-xo.html To answer the questions: 1. No, there is no difference in tolerance. Generally the slides are all milled in one way, with various changes (Ie: M17 is shorter, x5 has lightening cuts etc), but the core slide is the same. This is how you get many companies that make slides for the P320, Sig provides them a model of the slide under their OEM program and they add a design to it. It’s possible the slides can have variation depending on tooling, programming and such, but that’s not going to be common with factory made slides. Part tolerance does exist of course, for the most part Sig uses MIM parts, because not only are the parts made en mass, but injection moulding is generally considered a great way to keep high tolerance when mass producing. Therefore, you MAY be talking fractions of an inch, but almost never something so massive it will make you too far off spec. 2. No, there will be no difference so long as the cut out is made to the correct specs (give it take), you will not find any additional changes to the feel of the trigger. I hope this helps. Let me know if there’s anything else, you can always email me as well at sigmechanics@gmail.com
@@SIGMECHANICS Thank you for the great response. Yes, because of your video and others on TH-cam I became aware of the movement so I started looking for it. I have a xTen with no up & down no movement and my local shop has a well used p320Max for sale with no movement ether. Actually all current/new p320 in the 3 different local gun shops don’t show near as much movement as your p320 used in your video. But all M17/M18 (about 6 samples) have shown more movement than what I see in your posted video. Which leaves me very confused. Lol
I am interested. I was thinking about getting a P320 through Sig Custom Works, but their website states that this modification is not available with a manual safety. That would be a deal breaker with me unless something like this could be done.
I have a question for ya. The safety is only keeping the trigger from being depressed accidentally correct? But will not help with actually blocking the firing pin. And what is your take on the updated Sig P320 possibly of having a accidental discharge?
The safety blocks the sear from moving and stops the trigger from being pulled. The lock lever (striker safety) is independent from the manual safety mechanism. I don’t see how the gun can AD, so far (from specifically a scientific view), I don’t think it can AD. Trigger MUST be pulled in order to discharge so my opinion is people are causing an ND but are failing to report it as such.
Oh man I need this. I prefer manual safety and would love a kit that would help me add it to my FCU. Kind of hesitant sending the chassis to a service to get it CNC. Not sure why the heck SIG wouldn’t just create one chassis for the FCU and the M17/18. Cause I know the M17/18 FCU can be converted to remove the manual safety. I am in let us know if and when you release the kit or process.
@SIG MECHANICS I do have a p320 m18 however all the txg grips or xcarry grips have no safety cut out. Do you have a template? How did you make the cut out for the manual safety on that grip?
@SIG MECHANICS I can see alot of value in that safety cut out template for the grip, currently there is no solution on the market place for x carry grips with safety cut out.
I bought an M18 so I could have a manual safety, but Ive made so many upgrades/changes at this point that Im essentially building my handgun around the trigger module and safety. This product would have saved me loads of trouble and Id definitely buy one.
I have made and prototyped a large version, modelled after a P226. Works great but it’s not something I was going to release publicly (it was just for fun). I don’t think anyone makes anything like it so far for commercial sale though.
I’m trying my best to have it ready and available by the end of this month. Production is near completion and the manufacturer should be shipping soon. It will be made available through modguns.com (formerly SigSauerParts).
I have seen a kit on Sigs website. Is this the kit you speak of or something different? When I saw it online earlier today it said it was out of stock. It was a p320 manual safety kit.
They are two different things but ultimately work together. The kit I’m making allows you to convert the non-manual FCU and grip so that afterwards you can install the manual safety kit. Unless you modify the FCU (or already have an M17/M18), you cannot install the MS.
I would definitely be interested in the ability to add a manual safety.
Does that fix the drop issues? I'd think so, right?
@soundsnags2001 the drop safety issue came down to the weight of the original trigger, they swapped it out and the drip safety issue was fixed (in 2017). The MSAFET toolkit does add the extra level of piece of mind for some, but to me this gives your p320 a new level of modification, I like having the OPTION to have the MS or non-MS model.
Here’s a link to the kit, if you scroll down it also has a link to the updated and complete “how-to” video:
sigmech.store/products/msafe-t-p320-manual-safety-conversion-kit
Love the video, thank you! I already sent my FCu and had it modified. I purchased the Wmanual safety parts kit and now just need to intall it. I am old school and do not entirely trust any striker fire to not be able t have a misfire. I have seen glocks and just about every one of them have a murphy law day and go off. where a simple manual safety fixes or at least greatly reduces that to almost a 1 in a billion chance. I know many striker fire enthusiast will argue it slows your response time yadda yadda, all made up excused. I lift the safety on the draw after it clears the holser in and out of copetition and it has never ever effected my time.
Yes. Very intetested.
No idea why Sig would not make the FCU the same for the Safety and Non-Safety versions. Seems like more work for them. The P365 you can just buy the Safety lever parts and they fit right in to the FCU
That is exactly my thinking, would have been very easy to add them from the get go. Something like that on a stamp wouldn’t add cost as far as I see.
I refused to buy a P320 until I could get one with a manual safety. I would be interested in a conversion kit, but I would want it installed by a gunsmith.
Most any gunsmith should be able to do this work. Here’s the updated link to this project: th-cam.com/video/zemqe3gMqJs/w-d-xo.html
This will void the factory warranty.
It is much simpler to buy a P320 that is factory equipped with a manual safety.
This will ABSOLUTELY void the warranty. However it’s something people decide to do for various reasons. There are a few companies that have offered this as a service for several years and it seems like those that opt to do this really like it! Only down side is having to ship off the gun.
You are incurring 100% liability for any "bad stuff" that happens down the line. I would not do this. Buy an M17 FCU and be done with it.
In many ways, it’s strange to say it, but the reality is in every instance of modifying a firearm yourself, the fine line between “it failed on its own” and “I did it wrong” gets too blurred, if something goes wrong. It the main reason why all the part manufacturers make a note that all parts should be installed by a qualified Gunsmith. Even when it’s just swapping out a trigger, (which is a task almost all of us know how to do ourselves). It’s the unfortunate reality of liability .
However, I wholeheartedly agree that if you are not going to be 100% confident in the modification, the M17 or M18 is the way to go!
I would love to see a conversion kit come out for the p320, I have a standard compact and would feel a lot better to have the safety lever installed on it
I spent my 21 years in the Marines with a manual safety on the M1911 and M9. Sometimes I still reach for the safety on my P320. I would like the option to add it to all 3 of my 320’s.
This right here. I wasn't a Marine but I carried a 1911 as an EDC for over a decade and just incorporated removing the safety into my draw movement.
I'd totally purchase this tool. Completely see the value in this.
Knowing what I do about the P320, including what I learned here, I can conceive of no way that any of mine are capable of discharging on their own without the trigger being pulled either directly by finger manipulation or indirectly by the action of something else that does it. Unintentionally pulling the trigger by one of those means, especially the latter, is of course possible as countless Glock owners have discovered. Because of that possibility despite my best intentions and practices, I would definitely consider such a modification to the guns I have. I am therefore very interested in learning what would be involved.
Sure thing John, I’ll send you a message if this comes into production.
@@SIGMECHANICS Great! Thank you.
@@SIGMECHANICS I'm with John. As a Certified Factory SIG Armorer and professional gunsmith, I wholeheartedly agree with his points above. Having said that I would like the optionality of installing manual safeties on all my P320's. When I purchased my SIG P365, I bought it with the manual safety.
@@SIGMECHANICS please message me as well as I would be very interested in buying one
Coming from a 1911 this is what I have been looking for!!
Yes, I would like a manual safety for my P320. Why? Because I grew up shooting firearms that have manual safeties and I'm more comfortable with them.
Hi, this seems to be some sort of scam (they added an “@“ to my name to seem legitimate). Do not call the number I will report it to TH-cam.
YES! I'm 62 and I've been shooting guns and hunting since I was 10 years old. I only buy guns with manual safety's on them. I want the P320 X Five DH3 but they don't offer it with a Manual Safety. My P365X has a manual safety! My P226 is the SAO with a Safety. I think this idea of a Manual Safety conversion kit is a great idea! I think there are a good amount of people out here like myself that are maybe old fashioned and still prefer a manual safety!
This is one of the reasons why I made this kit. I know the manual safety is not something everyone wants and that is a debate that will go on forever, but for those people that do like it being able to have it is a game changer. Not to mention, my favourite feature is that once you do have the manual safety cut out, you get to decide at any given time if you want to switch back-and-forth.
I am interested in this.
Not sure why they don't have some kind of Safety from the get go.
I'm in! I would definitely like to see the process and toolkit.
Definitely interested in this, been wanting to make an x compact have a manual safety ever since they came out
So I put this into production 2 weeks back, hopefully it will be ready by January. Updates to follow!
Yes, please make this available. I have concerns with the non manual safety p320 that I have. I know the reports of it "just going off" are questionable and rare but this would give me some peace of mind. One question would be what tools are needed for the modification?
All tools would be included in the toolkit, so you wouldn’t need anything, just some time.
@@SIGMECHANICS Please keep us posted on when and how we can acquire the manual safety toolkit/jig.
Im not one for a safety on my guns but your content is always so informative and interesting and sparks my interest. If you produced a video on how to mix cake batter with a FCU I would probably watch
Ha! Thank you, that’s very kind of you to say. I’ve been working on a bigger video project recently where I am testing every P320 trigger in existence which I hope will drop in a few weeks. It’s high in data and I think it will help everyone, but especially those who are into modding their P320.
Keep your eyes open for that one! Thanks for watching and being a part of this community!
@@SIGMECHANICS you can count on it. Keep up the good work
I absolutely am interested. There is an outfit in California that installs a kit but I would have to ship the fcu to them. If your kit is affordable, I'm in!
I’d say this would be much more economical, not to mention re-usable!
I'm interested
First off…great videos! As far as the safety mod, it’s great. Would definitely consider it for some of my FCUs.
Keep in mind that even if you were to ever modify to have a manual safety on your P320, you can always switch back-and-forth between manual, safety and nonmanual safety at any time by swapping out one pin, and using a nonmanual safety grip module.
I chatted with Heath at Sig yesterday in response to the 6/14 "colorful parts" email and he says Sig is now offering a factory conversion of a P320 to add the manual safety lever for $265 including parts and a new grip module and return of your current grip module. Cost for a P365 was $160. presumably because the frame is already configured for a manual safety lever and doesn't require modification or replacement like a P320.
That’s pretty cool! I like how they constantly come with new designs to customize!
My project is a bit different, here’s the updated link with the details (the project went live not long ago):
th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I've been looking at various full size 45 and 10mm handguns for use as a woods gun. Although I like the Sig P320 XTen, I had pretty much decided against it because of the issues that have been reported with accidental discharge. Even after their upgrades, if you are counting on the mass of the trigger to be light enough in during a drop to not move the ~0.190 inch that is required disengage the other internal safeties, and if you're counting on never having anything snag the trigger in a holster, then I'm just not comfortable with it. Glock at least has the trigger safety. Springfield has trigger and grip safeties. And the DA/SA guns don't have this issue at all because of heavy trigger pull in DA mode and manual safeties. That being said, if you offered this manual safety, I would quite likely buy the Sig and it would certainly be upgraded with the manual safety. I think having a locked trigger would be better than trigger and grip safeties. And I like the gun other than this one critical issue.
Would love to add to mine. If you do get this into production, I would like to hear more details. I had always had a manual safety in my early years because of time in service and got use to them. Times have changed and most have chosen to go away from them. I have seen though most accidents though are not from holster pulls but from exposed triggers, that is where I believe a safety would be most helpful. If you roll this out, I could see myself making the purchase if I can find a gunsmith willing to do the work.
It should be available very soon via ModGuns (formerly SigSauerParts.com), no more than a few weeks from now.
@@SIGMECHANICS any updates? I’m interested in this as well!
I like the manual safety on the m18 and I wish Sig would offer it on the p320, I have the Sig Combat no MS and not sure I will carry it.
I’m in. It would be great to have an FCU set up that way for a need you think you won’t even need until you need it.
Agreed. Plus, you get the choice, you can always revert back to non-manual safety, you just weren’t able to add one easily…until now I guess.
Welcome back. Looking forward to sending money your way. I like the auto reset dry fire mod. I’m truly enjoying my P320 build
Thanks! It’s been a while because I’m working on a bigger project where I had to obtain every trigger that has even been in existence for the P320, but now I’m close to posting that video and I had time to make this quick “teaser”.
I’m glad your enjoying the build! It’s a great platform (especially for tinkerers).
It's definitely got my brain thinking. Does the design only prevent the trigger from move or does it have any affect on the striker?
This would allow you to install a factory manual safety. Therefore, you have every benefit the factory system provides which includes preventing the sear from dropping which will prevent the striker from releasing.
@@SIGMECHANICS That's great. I look forward to your videos.
It’s criminal the way Trudeau misrepresents Canada’s existing laws to the public to garner support. Canadians will have to get innovative in order to continue to enjoy their hobbies.
i have 3 different P320's and i'm extremely interested sir !!!
I would very much be interested and in line for a product to convert my own FCU!
That’s great! If there’s enough interest in this project, I will definitely be launching it publicly.
I’m in, when can I send you mine for conversion?
There’s no need to send it in. This kit could slow you to do this at home. The kit comes with everything you need , you only need to put the time in to get it done.
Obviously with the recent influx of "SIG News" this would be something worth putting out there. And after looking at other options that come with this (1911, Beretta 92 etc) I've decided to put one on at least one of my FCUs. Looking forward to it.
I carry a M18 safety off and round in the chamber, but like the fact that when doing things like unloading or loading I can pop the safety on for extra peace of mind. So I would say that if I had a striker fired weapon with no safety this mod would be something to consider.
Absolutely want this. I have a M17 issued to me by my Reserve unit and i like the ambi safety on it. My EDC is a x-series with no safety and i would love to have the option to carry it loaded with safety on instead of just loaded
Yes. It is a great option and allows concealed carry guys who prefer a bit of safety to feel a little more comfortable.
By the way, this project was launched a few months back. If you want to check it out the video is here:
P320 - MANUAL SAFETY FCU CONVERSION PROJECT
th-cam.com/video/VOudh7JT_4w/w-d-xo.html
Yes, I would purchase the modification if it became available.
I’d certainly like to be able to buy the frame with the cutout and the whole assembly installed and just put my slide and barrel on it
I would like a manual safety on a p320 to avoid a discharge when re holstering the pistol and there is an obstruction in the holster that could press the trigger. We do not always look to see if the holster is clear with no obstructions before we re holster.
Any news on this thing?
First shipment has arrived at ModGuns, I’m just going to make the install video and it will be available to everyone.
You have one available for the P365, so please, please, please, have this P320 conversation kit available to the general public. Like ASAP soon.
The P320 kit is actually already available! See this link for the updated video with details:
(UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT
th-cam.com/video/wOTGWaTOrqA/w-d-xo.html
The MSAFE-T Toolkit itself is available at www.sigmech.store
I'm genuinely curious, why would I want to add a safety? What are the pros? I have been a big Glock guy for years and p320's are new to me. I love them tbh. I have 3 and none have a safety. I do notice that this conversion is popular though.
There is no real pro or con, within the Sig community the aspect of modularity is huge, I believe that since it’s an upgrade that makes it so that you now have a new option to modify the gun, makes this very popular. Once you do this upgrade you can then swap back and forth between safety or no safety which I believe is a good way to not have to buy another FCU (just to have that option). It really ultimately comes to a personal preference when it comes to personal use/protection. Those with 1911 backgrounds love a safety, those with Glock experience may not even ever use it.
Yes, I would love to covert my 320 XTen into a manual safety. Does sig make the kit.
It actually works with Sig factory parts, here is the full how-to video (the project launched not too long ago). I should note that the kit is currently out of stock with new stock set to arrive in about a week with a few upgrades. So make sure to you subscribe to the “notify me” on the Sig Mechanics webstore to get an email when they’re back.
(UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT
th-cam.com/video/wOTGWaTOrqA/w-d-xo.html
Definitely interested. Already have the parts coming, just gotta make the cut. Would love some rough measurements
It’s hard to provide rough dimensions since the location needs to be pretty specific to connect the factory parts. The kit however will give everything perfectly without guesswork.
I’d definitely be interested. ABPrtotypes offers this already, but you might be the best “out there”.
Yes, AB is an amazing choice if you don’t want to or feel like doing the work. The kit however will allow you to have the MS without some of the hassle.
@@SIGMECHANICS sorry, I watched the video on my iPhone Mini with kids screaming in the room and sort of missed the main point :) I thought it was an option to send it to you. I'll charge my Dremel and stand by. Already have cut one module to accept the safety. THANKS
Hehe, I’ve been there! If you’re a tinkerer and enjoy the craftsmanship of working on your gun then you’re going to enjoy this… maybe wait for the kids to go to bed first though.
I had the manual safety conversion done on my P320 by AB-Protoype because the trigger is basically a single action only. I've had a lot of people disagree with that because (its a striker fired gun, not a hammer fired gun, so its not single action only and doesnt need a safety) and thats fine if you dont agree. You do you and I'll do me and I'll take the manual safety version.
For what it’s worth, I always considered the P320 SAO as well.
I am a long time 1911 guy and would dearly love to add a thumb safety conversion to my P320 Spectre Comp
Just feel like I need that additional comfort level.
There’s an update to this video here, with lots more information:
P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T)
th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I would love to be able to send my FCU and grip module to an armorer to have this installed. PLEASE let me know who does this🙏🏻 I have no concerns about warranty.
I actually released this project publicly a few months ago. Check out this video for more information.
P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T)
th-cam.com/video/zemqe3gMqJs/w-d-xo.html
Good idea. Was gonna make a couple comments, but you pretty much covered all the things I was gonna say (about the MUP-1 and companies that will add the safety cut to P320 FCU's and MUP-1 FCU's). I guess the main point would be how much is costs... and if that's worth it.
I believe you need to send both FCU and Grip and both are charged differently, or perhaps have to purchase a new grip. I would aim for half that. Plus, you would be able to possibly reuse this kit, which would be substantial if you have more than one FCU.
@@SIGMECHANICS Yeah, good point. It's nice too, because the safety cut doesn't interfere with the rest of the parts, so you can always add or remove the safety (esp if you have a non-safety cut frame, but that's just to make it look nice without the safety).
Yeah, reusing it is a major bonus too. I know several people that have several P320's who want to add a safety to at-least one of them, but never have, because they just don't want to have to mail their guns. Can't blame them though, I'm the same way.
YES, I want one! I'm so nervous about the light trigger of my X TEN I've been carrying it with an empty chamber.
This works great on the X-Ten. Here’s the updated video with more info:
P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T)
th-cam.com/video/zemqe3gMqJs/w-d-xo.html
I would buy one, please make it available.
I believe this would be a big seller. I recently had the FCU frame milled out to accept a manual safety because of continued accidental dischargeproblems with the P320
I always felt safe with the P320, but I also always understood that piece of mind with your carry is far more valuable to an operator. Even the slightest mental hesitation makes that firearm dangerous, even if it’s not. Hopefully, something like this will provide that peace of mind at what I would assume to be a very low price.
So far everybody seems to be very positive with this project so I’m going to see about getting this into production soon. I just want to make sure I can provide everything down to the bits before this becomes public.
Does the m18 manual safety block the sear from releasing the striker or just the trigger from being pulled? I'm a Little nervous using the m18 as a everyday carry
The safety essentially physically blocks the trigger from moving forward, there is a pin on the safety lever that locks into a slot in the trigger, which then stops the interaction between it and the sear.
Did this ever go anywhere? I’d be interested in purchasing.
Yes! It launched about a year ago, here is the full video… let me know if you have any questions.
(UPDATED) P320 MANUAL SAFETY CONVERSION TOOLKIT
th-cam.com/video/wOTGWaTOrqA/w-d-xo.html
i’m interested! i’d like to add a safety to my si smc.
I'm honestly shocked to learn Sig does not provide this option. It seems uncharacteristic of an otherwise top notch gun company that prides itself on modularity.
Part of the reason I released this project is because I wholeheartedly feel Sig should just include this in every FCU they make, it’s such a minor thing to add into production! Here’s the updated link with all the details for this project:
th-cam.com/video/wOTGWaTOrqA/w-d-xo.htmlsi=i1VRUvA6qRsNL8Xn
I own the Carry AXG metal. It is my favorite pistol. However, with latest lawsuit I just won't carry. I was told it was not possible to add manual safety. Now that I see it is potentially possible, I now face the problem that my frame is stainless, which means as much as I would jump on the opportunity, it won't work with my metal frame .
I have not tested it on the AXG, although i imagine the process would work if you first remove the grips. I do intend to try it out though. I will report back once I do.
I also would consider this project
My question is, how can I get this kit? I would definitely feel a little safer with this feature.

I didn't even realize the safety equipped FCUs are different. I was about to buy a safety, thinking I could just stick it in. Seems weird that they make a specific modification to the FCU for a modular design.
I always thought so too. It would cost nothing to just add it.
I also would like a manual safety on my 320. I would like to see a factory option to install the manual safety.

Any update on this? I would love if I could have one sent to Australia, obviously it would be a lot easier to convert it myself as opposed to trying to send an FCU overseas!
When I make the notification that it’s available, send me a message on Instagram and I’ll see what I can do to your location.
Would this method also work with the P320 xten? Thinking of picking one up, but it currently has no manual safety version.
I jus looked into this now and as far as I can tell… it will work. I’m hoping I will get an opportunity to actually try it out soon.
great idea! I've USED AB Prototype and their work was great - but you need to ship R/T which is costly, plus it's a cost per FCU
Always wondered why Sig doesn't just cut the needed slot in ALL FCU's - and give the option of manually adding the parts later if desired
That’s my main pain point with the service as well.
Here’s the update to this video:
th-cam.com/video/zemqe3gMqJs/w-d-xo.html
@@SIGMECHANICS I may still buy this in case I buy another P320 FCU without a manual safety. Thanks for your videos and now this incredibly innovative tool
I am absolutely interested. Please let me know as well! Thanks for your vids.
I’ll make an announcement as soon as it’s available. Thanks for watching!
Yes, I'm definitely interested.
I am interested in the "fixture".
Would this work with the x5 trigger. I think the trigger geometry is different to allow a lower pull weight.
This works with ANY P320 FCU. (Including the X5 setup). Here’s the updated video with all the details…

I would love this on my xten.
This is the information I’m looking for.
i would be interested. would i be able to convince you to send me the dimentions and location for the pocket on the FCU for my own use? as i will not need a jig.
I can would but I don’t have it set off t that way. I also would NOT recommend to free hand it. The bits will jump and it will be hard to gauge as you go without parameters in place.
Absolutely would purchase if it becomes available

I love this! It would be another way to customize FCUs, which is the whole point of their existence! I think some jigs for milling the grip (including the axg side grips) would be great too
Jigs for cutting the grip can be bought on eBay very cheaply, or 3d printed yourself
Yes, grip cutout jigs been around for some time. This is more of a “complete” kit to get you from start to finish.
I've seen the jigs for cutting the grip, but I thought you were supposed to remove the side panels and do them separately. Either way, it shouldn't be too hard EXCEPT that the panels need to be milled to be made flush with the safety, and I know I'm not going to be able to do that (without making it look terrible). Either way the safety conversion kit would still be awesome!
So I’ve found over trials that there is an order of operation for this to work really well, mostly it’s time investment and direction of tool travel, but even those inexperienced have made it work in testing. I hope to get a full “how to” video out soon.
@@Dante-420 it's actually really easy with the polymer grips, few minutes with a dremel and done. even if you mess up a bit, the safety itself is big enough to cover a minor error. Dunno about the AXG though - that's aluminum, whole different beast, never tried it. But aluminum is pretty soft...I think you might want a better jig, but a router should be able to mill it easy enough
Edmund -
I've really enjoyed your other videos, however you really hit it out of the park with this awesome kit. I just finished adding the manual safety to my p320 X-five (original version, not the Legion version) using your kit, and am really pleased with how well it works.
For me, The key to success was your "P320 Manual Safety Conversion" video here on TH-cam... Without your very well made and thorough instructions I'm not sure I could have completed the conversion successfully, but following it very closely made the process painless and straightforward. Also as a side benefit, I learned a lot more about the p320 in doing this conversion.
Thank you so much for the work you put into the Kit AND the great step by step video - I have mostly shot 1911's for decades so I am used to safeties, and now my competition x5 has the same manual of arms as my 1911's and 2011's.
Your Kit and your step by step video are absolutely first rate! Keep up the fabulous work!
Hi Phil!
Thank you so much for your kind words and support!
Since this kit is so new in the market, it’s extremely encouraging to start hearing people are not only using the kit, but also finding it a useful and educational experience.
If you get the chance, I’d really like for you to leave a review/ testimonial on the ModGuns site about your experience!
Thanks again Phil, if you ever need anything at all let me know!
@@SIGMECHANICS I was very happy to leave a review/testimonial on the ModGuns site - it's the very least I can do to thank you for the obviously very hard work and time you've spent on this project. By the way, I just got back from the Range about an hour ago, and really loving the newly installed Manual safety - before I went, I was a little bit concerned that the Safety levers seemed smaller than the lever's on my 1911's, but after about 20 minutes or so, I really don't notice much difference at all. They work GREAT!!! Thanks Again!
@@SIGMECHANICS I just checked the ModGuns site and I don't see my review/testimonial on it - I tried a couple times, but still don't see it yet so I sent them an email. If the testimonial doesn't show up by Monday, I'll follow up with them....
I got an email from modguns that they just reviewed and approved several reviews, so I see 4 reviews on their site now (the first 2 are mine - don't know why it was duplicated), but it looks like all the reviews have been truncated to 220 chars even though the web site allows you to input much more text. I emailed them again just to let them know as all the reviews have been truncated to 220 chars... At least there are 4 reviews on their site now.
Ah, good catch. I will let them know about those character restrictions. I do know that since the site is completely te-vamped as of a few weeks back, there are small bugs they need to clean up in the next few weeks.
In any case, thanks again!
This is a great option!
I think this is a great idea.
When can we see(purchase) such tool to do this work. great job on this
I should have this available end of January. Stay Tunes.
Are these conversions for sale now if so where can one be purchased and do you happen to have any for 365 as well?
Yes there’s another batch coming soon to ModGuns, the 365 does not need this sort of kit since the FCU is made for adding a MS right from the factory.
Would like to see this as an option to purchase

@@SIGMECHANICS , yes, but my new P365XL arrives Friday. itll take a couple months for my wallet to recover.
I like pistols with a manual safety. Since Sig doesn't sell FCU with manual safety, I bought used m18 just to get the FCU. I would love to convert all my FCU to manual safety if I knew how.
i'm very interested
Howdy Eddmen 🤠
I have a question, I have noticed by handling many p320, p365 & m17/m18 models. From what I owe to many other gun shops with new and used SIG’s.
With every single manual safety m17/18 I’ve handled, I noticed a bit of sucking down movement of the rear part of the upper slide when dry firing without the magazine installed (with mag installed the movement is less because the mag follower is pushing up, but still very noticeable)…
Now with all the non manual p320 & p365’s I’ve looked at, there is no perceived to very little sucking down movement with the rear upper slide when pulling the trigger with or without the mag in.
When checking for slide and FCU movement/ wiggle/ relationship tolerance, it didn’t seam like the non manual safety models had much less movement/ tighter tolerances.
I believe I understand that the sear moves in a downward movement when the trigger is pulled and what ever slop that is in the striker fire housing, slide and FCU gets tightened up by the friction with the sear and its downward movement.
Now I was told by a sig expert that all sig models are Assembled guns vs fitted for better assemblies with tighter tolerances, even if it’s a legion model. And so one could get a gun that fits tighter or looser than another no mater the model. Which would mean all p320’s would have variation of slide movement no matter the model, and a M17 could have next to no movement and a xFive have quite a lot. Which is not my finding with the sample size of 20 I have experienced so far.
So my two questions for you are.
•One, do the M17/m18 models run different tolerances or parts? Like is the slide hole for the striker fire unit bigger or the striker fire housing smaller?
•Two, when modifying a non-manual FCU into a manual FCU, does the movement change?
Thank you for your time.
Great analysis. To start I will share this video where I talk about the slide movement and why: th-cam.com/video/itGqqq8IcL8/w-d-xo.html
To answer the questions:
1. No, there is no difference in tolerance. Generally the slides are all milled in one way, with various changes (Ie: M17 is shorter, x5 has lightening cuts etc), but the core slide is the same. This is how you get many companies that make slides for the P320, Sig provides them a model of the slide under their OEM program and they add a design to it.
It’s possible the slides can have variation depending on tooling, programming and such, but that’s not going to be common with factory made slides.
Part tolerance does exist of course, for the most part Sig uses MIM parts, because not only are the parts made en mass, but injection moulding is generally considered a great way to keep high tolerance when mass producing. Therefore, you MAY be talking fractions of an inch, but almost never something so massive it will make you too far off spec.
2. No, there will be no difference so long as the cut out is made to the correct specs (give it take), you will not find any additional changes to the feel of the trigger.
I hope this helps. Let me know if there’s anything else, you can always email me as well at sigmechanics@gmail.com
@@SIGMECHANICS Thank you for the great response. Yes, because of your video and others on TH-cam I became aware of the movement so I started looking for it. I have a xTen with no up & down no movement and my local shop has a well used p320Max for sale with no movement ether. Actually all current/new p320 in the 3 different local gun shops don’t show near as much movement as your p320 used in your video. But all M17/M18 (about 6 samples) have shown more movement than what I see in your posted video. Which leaves me very confused. Lol
I am interested. I was thinking about getting a P320 through Sig Custom Works, but their website states that this modification is not available with a manual safety. That would be a deal breaker with me unless something like this could be done.
Here’s the link to the full how-to video and kit info:
P320 MANUAL SAFETY CONVERSION (HOW-TO USE THE MSAFE-T)

@@SIGMECHANICS hey trying to view the video. But it says it’s private.
I have a question for ya. The safety is only keeping the trigger from being depressed accidentally correct? But will not help with actually blocking the firing pin. And what is your take on the updated Sig P320 possibly of having a accidental discharge?
The safety blocks the sear from moving and stops the trigger from being pulled. The lock lever (striker safety) is independent from the manual safety mechanism.
I don’t see how the gun can AD, so far (from specifically a scientific view), I don’t think it can AD. Trigger MUST be pulled in order to discharge so my opinion is people are causing an ND but are failing to report it as such.
@@SIGMECHANICS thank you so much!
Oh man I need this. I prefer manual safety and would love a kit that would help me add it to my FCU. Kind of hesitant sending the chassis to a service to get it CNC. Not sure why the heck SIG wouldn’t just create one chassis for the FCU and the M17/18. Cause I know the M17/18 FCU can be converted to remove the manual safety. I am in let us know if and when you release the kit or process.
I’d give it a try
I would love the ability to add a MS to non MS models! Especially with me wanting to pick up another one for competition.
I think that's a great idea. By chance do you have a template for the x carry safety cut out? I would like to get a txg x carry grip and convert it.
If you have a P320, the FCUs are all the same! Modularity is one of my top reasons for enjoying this platform.
@SIG MECHANICS I do have a p320 m18 however all the txg grips or xcarry grips have no safety cut out. Do you have a template? How did you make the cut out for the manual safety on that grip?
Oh! I see what you meant. Yes, this kit would let you cut both the FCU and x-series grip module.
@SIG MECHANICS I can see alot of value in that safety cut out template for the grip, currently there is no solution on the market place for x carry grips with safety cut out.
I like the x grip and have it on all my p320s, so I started with the x-series first.
Yes, that will be great! Where can we have the mods done? Do you have a list of companies? Thanks.
It actually already available! Here’s the updated video…

@@SIGMECHANICS thank you!
I'd be interested. I didn't realize when I bought my FCU that it doesn't come with the holes for a safety pre drilled.
I bought an M18 so I could have a manual safety, but Ive made so many upgrades/changes at this point that Im essentially building my handgun around the trigger module and safety. This product would have saved me loads of trouble and Id definitely buy one.
Has anyone made a bigger manual safety where you can rest your thumb on better like on a 1911?
I have made and prototyped a large version, modelled after a P226. Works great but it’s not something I was going to release publicly (it was just for fun).
I don’t think anyone makes anything like it so far for commercial sale though.
@@SIGMECHANICS cool! Would love to see a picture. 😎🤓
I would be interested
Yes. I want to convert my xten to add a safety. But if I change grip modules I'd hate to have to keep doing it.
I need this safety conversion like now lol
I’m trying my best to have it ready and available by the end of this month. Production is near completion and the manufacturer should be shipping soon. It will be made available through modguns.com (formerly SigSauerParts).
I have seen a kit on Sigs website. Is this the kit you speak of or something different? When I saw it online earlier today it said it was out of stock. It was a p320 manual safety kit.
They are two different things but ultimately work together. The kit I’m making allows you to convert the non-manual FCU and grip so that afterwards you can install the manual safety kit.
Unless you modify the FCU (or already have an M17/M18), you cannot install the MS.
@@SIGMECHANICS okay I see now. That is a product I would very much so be interested in.
