I love your videos bro. I bought the manual safety kit/template about a year ago. After I milled the fcu and installed the safety, I took it to a local gunsmith just to get a second set of eyes more experienced than myself on it. He was actually pretty impressed and had never seen anyone do one themselves. Thanks again for the videos
@@SIGMECHANICSStudied this thoroughly last week, so it is an amazingly unexpected find.😊 Had to let you know. Happened to just tell the local gun store sales clerk all about it today. Really rehabilitates the original P320 sear and striker design alignment with the possible previous resulting movement.
Thank you very much for this extremely interesting video. It should reassure owners of M17/M18 that the safety of their gun is working very efficiently which means that their pistol is safe to use.
Always appreciate the videos. I think I've seen them all at least once. One thing I don't recall if you covered was the drop safety of the sear itself... and I don't mean the mechanisms added to protect if the sear ever does fail (like the 2nd sear ledge and the striker safety)... but if there is something that's designed and/or inherent that stops the sear from ever dropping in the first place from kinetic energy, like a drop or hard shock of some kind. With the sear pivot/pin being so far off to one side and not in the center, it seems very off balance... and off balance usually means that it will want to turn/rotate one way or another if dropped at specific angles or ranges of angles. I know that the safeties would at-least stop the striker from setting off the round if the sear ever did fail... but it's a little tougher to imagine why the sear wouldn't fail if dropped the right way. (For example, Does the opposite/rear side of the trigger bar stop the sear from rotating if the trigger is not pulled? I've seen some DAs and DAOs that work like that, but I'm not sure if that's the case with the P320 also. I've always been a strong believer that if a person owns a firearm, he should know precisely how that firearm works, so he can inspect his firearm and know 100% if it's in safe working condition or not). Forgive the long explanation. Not an easy thing to describe.
I didn’t specifically go into the physics of the sear movement when dropped, it would be interesting for sure but I’m not sure how I could accurately capture that data in a test. I’d have to see what type of method could work.
@@SIGMECHANICS Good point. I'm not really sure. I always wondered when you pushed the sear down with a punch if kinetic energy would also be able to push it down. Like with a Glock, there is a shelf that the trigger bar rests on and it cannot be pushed down at all while the trigger is not being pulled... and only when the trigger is mostly pulled does the trigger bar ever leave the ledge to be able to drop down. With the P320 though, I'm not sure if any mechanism exists. I'm not sure what the best way to prove/disprove that would be. I'll have to take a look when I get a chance and see if I can come up with anything. I guess that's one good thing about the P320 FCU. Unlike the LCP style guns it contains all the fire control lower parts... so I hope I can get a good look at one when I get a chance.
Great content. Thank you for sharing your knowledge. I learned quite a bit on your channel. Is there any way you will be developing an extended thumb safety. Please....The manual safety is quite small.. I would pay a good penny for one that works. Be well
Thank you! That’s very much a good possibility at this point. The hardest part is only to come up with a novel design that encompasses all the various things people want to get out of it into one good looking design.
I'm thinking of getting the M17 now that I've seen a couple of your videos it's actually well done. Maybe there were hiccups at the start but so as any other mayor brand.
You absolutely should see a pro if you’re truly not sure or capable. Realistically, it’s super easy and I would say 99% of people have done this modification do it themselves with time and a TH-cam video.
I have wondered what would happen if the trigger were forced with the safety on. Great experiment and explanation! I think blocking the sear would be preferable, but it's impressive what SIG was able to do with what was an afterthought safety design for the military trial (I could be wrong about that, but I don't think the safety existed before the XM17 trial).
I have a design I’m working on that will block the sear physically but I need to get some made in order to test. I want to make it a drop-in part if I can so it’s not much more work to install it.
great video as always! i've been following this series since your 1st version (as well as your other videos!). maybe i missed it, but so far i have not seen any video on converting the standard grip module even though your version 2 of this conversion kit has the templates that will allow for converting the older grips. is this process exactly the same as that for the x-series just need to use the appropriate templates? or are there differences that need addressing due to the differences in the grips?
Thank you. You’re absolutely right, and I will make a video for the standard grips. The process is exactly the same. The only difference is there is a slight modification in the jig that allows the template to properly situate itself on the grip. it works with both standard and X series so there are no problems or changes the affect one over the other.
I wish I found your TH-cam channel sooner.. New owner of a SIG P320 M18 CA-edition here. I made the mistake of forcing my takedown lever open with a wrench to start disassembling with an unloaded magazine in the gun!!! Everything seems to function properly but I would like your expert opinion if forcing it open that way can damage any mechanisms. Thank you!
There must be some sort of damage. The takedown lever bar (black bar that runs the length of the FCU), would need to move back, the backward movement is what makes it so that you can have a mag inserted as the bar would hit the mag tube body and not let the bar move far enough for it to disengage the sear. That bong said, if you successfully did that, something would have to be left damaged, the mag tube or the takedown bar. Have you opened it to check?
Thank you so much for the updated video! I had commented after seeing your other very detailed breakdowns. One question though: in the case of these theoretical and unlikely uncommanded discharges without a trigger pull, does this pre-sear engagement from the MS do anything to prevent the striker from moving forward or is it only the firing pin block? The 365 seems to be the safer design in this case but would love to hear your analysis. Thank you.
The manual safety prevents the trigger bar from touching the sear which intern prevents the striker from moving forward since it remains blocked by the sear. Internally, when you pull the trigger, even with the manual safety activated, you are still lifting the lock lever on the striker.
@@SIGMECHANICS enough movement to disengage the striker safety lever? I recall a very short trigger travel in your other video for it to disengage, .090 I believe. I am assuming the manual safety doesn’t allow the trigger to move that full .090? Not sure though. However, would still need to pull the trigger .11 for a discharge. Thanks
Edmund, have you given though to producing a slightly wider safety lever? The OEM isn't horrible but for those of us with shorter thumbs, it would be a welcome piece.
This is such a great video. My only question is regarding the built in safety lock tab mechanism that prevents the striker from moving forward prior to a trigger pull. Is it disabled at any point during the first part of initial trigger travel before the safety stops it? Or after the trigger has been pushed beyond the first threshold of abuse? As you showed on the other sig model, when the safety was on, it physically blocked the striker. To me it seems that the p320 design is inherently less full proof as the other internal safety could fail and then nothing would be stopping the striker from discharging even though the manual safety is on. Thoughts?
I’m going to try and answer this with another video that does really deep into the safety lever. In this video, I am exploring what happens when you use a tunable trigger and how it disengages internal safety. You will see the Mechanics on full display during this video. Take a look and let me know your thoughts. EFFECT OF ADJUSTABLE TRIGGERS ON P320 SAFETY th-cam.com/video/8WqpL7A5zd8/w-d-xo.html
@@SIGMECHANICS wow you are blowing my mind with how thorough you are in using the scientific method to test and educate. I cannot thank you enough and I have purchased the msafe-t kit. As to my question, upon watching the adjustable trigger video, my suspicion is that the internal safety is getting partially compromised but not completely. A way to maybe test this would be using the same gravity drop method you used to find the safety delete point but with the manual safety engaged to see if the manual safety stop point crosses reaches the delete line or if it crosses after the safety is pushed past the abuse point. Although that drop test would be a helpful indicator, the truest test would be finding a way to test the safety delete point with manual safety engaged from first stop past abuse point while the striker spring is engaged as the tension from the spring may push beyond the small portion of the internal safety that may have stopped the striker in a gravity only test. I am not sure how that could be done but would be interesting to see. Thanks so much for responding to my question.
I would like to be able to buy a Fire Control Unit from Sig's web site for my P320 pistol and a Module Grip with the cut already in it for the Manual Safety.
That chevron broke on the detent and caused my manual safety to malfunction on my CA Xfive legionwhen I was practicing. Any idea what caused the break? Love your videos!
@ Yes! They asked me to RMA it, I was shocked when it happened. I ride the safety when practicing, that might have contributed but a lot of people esp 1911 users do that. Only 500 on the legion when it happened.
Question: would the striker safety lever stop a striker from dropping from the second sear notch, or is the second sear notch “after” the striker safety lever?
The second notch is mainly to deter an AD should there be a split second jostling of the sear. However, the true safety is the striker lock lever, which, without a trigger pull will not be lifted, and therefore the striker would not be able to make it into the breach face.
I belive on the Airsoft version of the m17 the safety worked also kinda like it but instead of stoping the trigger bar of behing puled it pushes the bar down so the hock on it can’t press the release mechanism
@@SIGMECHANICS oh I would love a video about it tho it is a bit harder to put back together then to disassemble it The only problem I have with taking of the outer barrel from the inner barrel is the pin holding both together once out it’s hard to hammer back in and is bend easily if you want to know how it lookes like it’s part number #02-04 I love this pistol from the way it looks and as a wrong handed shooter I love the reconstruction to left handed with the mag catch and release I also installed a flat adjustable trigger I made the trigger pull as short as possible I only have like 1mm of travel before the brake and it stops right after but is still able to reset but the movement of som parts has a bit of play room so I could not completely eliminate the travel My main Airsoft gun is a Vfc hk416a5 GBB and there the trigger has no travel it’s already at the wall when cocked
Not technically, although you could make the cuts into the frame, it will not let you also cut the side panels, that would need to be done free-handed. I have seen quite a few people accomplish it but it’s not what the kit was specifically made to work with.
@vahngeo2260 sure, I can only recommend (from others’ experience) add more tape u see the grip jig to “thicken” it, since the AXG frame is thinner than the polymer. Then make sure to use a thumb to hold the jig down as you cut to make sure it won’t move on you.
Can you look into the potential of an aftermarket ejector in the chance that the ejector is bent and broken, and FCU couldn’t be replaced in specific situations? (Canada banned all future pistol sales)
That’s actually a very important topic, I will look into this and see about possibly finding an elegant solution. The Canadian gov. really overstepped their bounds with their ban on licensed owners.
Thanks for the video. I'm afraid it's over my old man head. I hope you can answer my question. I have an older p320, that I had upgraded on the recall. I just sent it back to Sig and had them put in the manual safety on it. I haven't gotten to shoot it yet because of weather. Just want to know what you think of my decision. Thanks
That’s a great question, and you made the right call. Although there are varying debates about pre vs post upgrade and which is “best”, the new version adds new parts and uses better mechanics. There are quite a few differences so I’m sharing with you this video that will give you all the details… P320 - PRE v. POST UPGRADE ANALYSIS th-cam.com/video/VmwpkJuIR00/w-d-xo.html
Thanks Bud. I have been hunting or shooting my whole life. All the guns except BB guns had a safety. The Sig was my first striker fire pistol. After I got it (and hearing a lot about it going off, which I think now was seventy percent BS) I just couldn't feel comfortable with it. That's why I sent it back to Sig. Thank you for the reply and I'm going to check out the link to your video. I really appreciate your reply and help.
I paid attention to the video but I may have missed it. So from my understanding the P365 safety blocks the sear from dropping, but the P320 safety only prevents the trigger from being pulled. So theoretically, if one were to drop a P320 with the manual safety engaged, it could still fire if the sear engages/disengages since the manual safety does nothing to prevent the sear from moving? If I am understanding correctly it would explain why the P365 is a design with way less safety complaints despite being carried AIWB more than the P320
To be able to discharge the trigger would have to be pulled back enough from the inertia caused by the fall. If the sear however drops (just the sear with no trigger pull), then 1. The second sear ledge could capture the striker and 2. The striker still would not hit the primer as the striker’s lock lever would not have been disengaged.
@@SIGMECHANICS Then all these cops shooting themselves are having negligent discharges. And I'm not being sarcastic or passive aggressive. From an engineering stand point it seems impossible for these guns to go off by themselves.
@paddypibblet846 The unfortunate truth is many TH-camrs and influencers get more clicks with the negative negative than taking the time to investigate the issues. If I could ever prove a mechanical issue I’d be the first to report it and show my work in order to bring clarity and force changes. However, to date, I’ve remove all safeguards and manhandled the P320 in ways WAY out of spec and I could never get it to fail the way it’s been claimed.
@@SIGMECHANICS Agreed. I think what didn't help the Sig when it comes to how people currently perceive it... was the original drop safe problem (which they fixed) of the gun firing when being dropped. After that it was destined to be disliked. It may go the way of the Beretta. At first disliked and hated by service members/police, but once all the negative misinformation wears off, it will be highly regarded. I was always suspicious of all these claims of the gun "going off" by itself because I remember cops saying the EXACT same things about Glocks.
So you think the P320 is a legit and robust system? Well designed? I’m just use to Glocks, so I wanted your opinion because I’m thinking about getting the M17 commercial. Thank you.
Yes, very much so! There is a lot of negative content out there that uses an older issue (drop safety in 2017), to promote doubt / fear about new and unproven issues like unintentional discharges. The former was dealt with in 2017 by issuing a new lighter trigger. The latter is not true and is not something that has ever been proven using scientific methods to replicate the problem. To answer your question, the more I use and put the P320 through testing the more I respect how well engineered it is as a product.
So far I haven't been able to find a complete kit that has the template & I have a couple of 80% fcu that I started last year & completely halted my 2 builds due to unintentional discharge videos. . Seems like Sig refuses to help you if your fcu is 80%
Oh, the MSAFE-T kit does not come with the levers, but if you contact a company like Desert Depot, you could get both I think since they sell the kit and the parts. I believe Sig doesn’t since the 80% are an idea from a company outside of Sig, so there’s no customer support on a product they never made. For stuff like that you can approach someone like Sig80BitKits, they sell 80% and might help resolve issues.
Great video, yet it makes no sense to me when a good handgun with a manual safety can already be purchased. If a person is not sure enough of their ability to carry a handgun without a manual safety, why purchase one just to add a manual safety? I just would't buy a Sig p329 or a Glock.
Agreed, and personal preference and experience play a big roll. It’s also possible it was purchased without knowing what models can and can’t have one. The Sig Mechanics MSAFE-T toolkit is an extremely popular tool now and I found that that people use it mainly because they like to have the OPTION to add a factory MS, not necessarily because they use it often.
? But how does any of this sophistication really account for the gun firing without the trigger being pulled. Noone with a brain can deny this isn't happening.
The video is not referring to the instances you’re talking about. It’s just to show the function of the mechanics behind it. For all intents and purposes, to this day there is still not been anybody that can replicate the p320 discharging in the way that you are mentioning. Even with the case where the drop safety was found to be compromised, it was possible to easily replicate that scenario. I’m not saying that it is impossible only that it’s not probable and that so far the only way to make the 320 discharge is by pulling the trigger a certain distance to disengage all the safeties internally. If you’re interested, I did make a video that goes into more detail: th-cam.com/video/R0MpcFEXWhc/w-d-xo.htmlsi=VYW-eXLI4dUtEfPh

The only problem I have with taking of the outer barrel from the inner barrel is the pin holding both together once out it’s hard to hammer back in and is bend easily if you want to know how it lookes like it’s part number #02-04
I love this pistol from the way it looks and as a wrong handed shooter I love the reconstruction to left handed with the mag catch and release
I also installed a flat adjustable trigger I made the trigger pull as short as possible I only have like 1mm of travel before the brake and it stops right after but is still able to reset but the movement of som parts has a bit of play room so I could not completely eliminate the travel
My main Airsoft gun is a Vfc hk416a5 GBB and there the trigger has no travel it’s already at the wall when cocked
Does your MS conversion kit work with the AXG grip module?
Not technically, although you could make the cuts into the frame, it will not let you also cut the side panels, that would need to be done free-handed. I have seen quite a few people accomplish it but it’s not what the kit was specifically made to work with.
@@SIGMECHANICS Thanks. The frame is all I was wondering about. The grip panels, easy peasy.
@vahngeo2260 sure, I can only recommend (from others’ experience) add more tape u see the grip jig to “thicken” it, since the AXG frame is thinner than the polymer. Then make sure to use a thumb to hold the jig down as you cut to make sure it won’t move on you.
@@SIGMECHANICS Cool....thanks!
Can you look into the potential of an aftermarket ejector in the chance that the ejector is bent and broken, and FCU couldn’t be replaced in specific situations? (Canada banned all future pistol sales)
That’s actually a very important topic, I will look into this and see about possibly finding an elegant solution. The Canadian gov. really overstepped their bounds with their ban on licensed owners.
@@SIGMECHANICS If someone can make a sear housing that protrudes up more, in place of the damaged/removed ejector, that would be all that’s needed.
When TH-cam removes all Armorer "how to" modify, fix, maintain long guns, and maintain handgun type videos, where will I be able to find you?
Yikes, I hope not. Long term I will have all these videos on the SIGMECH website and self hosted so it won’t happen.
Thanks for the video. I'm afraid it's over my old man head. I hope you can answer my question. I have an older p320, that I had upgraded on the recall. I just sent it back to Sig and had them put in the manual safety on it. I haven't gotten to shoot it yet because of weather. Just want to know what you think of my decision. Thanks
That’s a great question, and you made the right call. Although there are varying debates about pre vs post upgrade and which is “best”, the new version adds new parts and uses better mechanics. There are quite a few differences so I’m sharing with you this video that will give you all the details…
P320 - PRE v. POST UPGRADE ANALYSIS
th-cam.com/video/VmwpkJuIR00/w-d-xo.html
Thanks Bud. I have been hunting or shooting my whole life. All the guns except BB guns had a safety. The Sig was my first striker fire pistol. After I got it (and hearing a lot about it going off, which I think now was seventy percent BS) I just couldn't feel comfortable with it. That's why I sent it back to Sig. Thank you for the reply and I'm going to check out the link to your video. I really appreciate your reply and help.
Anytime, and if you have further questions let me know.
I paid attention to the video but I may have missed it. So from my understanding the P365 safety blocks the sear from dropping, but the P320 safety only prevents the trigger from being pulled. So theoretically, if one were to drop a P320 with the manual safety engaged, it could still fire if the sear engages/disengages since the manual safety does nothing to prevent the sear from moving? If I am understanding correctly it would explain why the P365 is a design with way less safety complaints despite being carried AIWB more than the P320
To be able to discharge the trigger would have to be pulled back enough from the inertia caused by the fall. If the sear however drops (just the sear with no trigger pull), then 1. The second sear ledge could capture the striker and 2. The striker still would not hit the primer as the striker’s lock lever would not have been disengaged.
@@SIGMECHANICS Then all these cops shooting themselves are having negligent discharges. And I'm not being sarcastic or passive aggressive. From an engineering stand point it seems impossible for these guns to go off by themselves.
@paddypibblet846 The unfortunate truth is many TH-camrs and influencers get more clicks with the negative negative than taking the time to investigate the issues. If I could ever prove a mechanical issue I’d be the first to report it and show my work in order to bring clarity and force changes. However, to date, I’ve remove all safeguards and manhandled the P320 in ways WAY out of spec and I could never get it to fail the way it’s been claimed.
@@SIGMECHANICS Agreed. I think what didn't help the Sig when it comes to how people currently perceive it... was the original drop safe problem (which they fixed) of the gun firing when being dropped. After that it was destined to be disliked. It may go the way of the Beretta. At first disliked and hated by service members/police, but once all the negative misinformation wears off, it will be highly regarded. I was always suspicious of all these claims of the gun "going off" by itself because I remember cops saying the EXACT same things about Glocks.
Where do we find the template for cutting out the cavity area for the detent?
It’s available at www.sigmech.store
So you think the P320 is a legit and robust system? Well designed? I’m just use to Glocks, so I wanted your opinion because I’m thinking about getting the M17 commercial. Thank you.
Yes, very much so! There is a lot of negative content out there that uses an older issue (drop safety in 2017), to promote doubt / fear about new and unproven issues like unintentional discharges.
The former was dealt with in 2017 by issuing a new lighter trigger. The latter is not true and is not something that has ever been proven using scientific methods to replicate the problem.
To answer your question, the more I use and put the P320 through testing the more I respect how well engineered it is as a product.
@@SIGMECHANICS thanks for the reply
So, after all that is the P320 safe to carry?
I've been carrying mine anyway, even though a lot of people say it's unsafe.
Its as safe as any gun out if not safer. Keep shi* away from the trigger and there is no issue.
I would worry more about the q person carrying the handgun than the handgun itself.
Can you share the 3d model?
Sorry I cannot. Aside from the cost and work to make them, these files can be used for manufacturing and may be illegal to share.
So far I haven't been able to find a complete kit that has the template & I have a couple of 80% fcu that I started last year & completely halted my 2 builds due to unintentional discharge videos. . Seems like Sig refuses to help you if your fcu is 80%
Oh, the MSAFE-T kit does not come with the levers, but if you contact a company like Desert Depot, you could get both I think since they sell the kit and the parts.
I believe Sig doesn’t since the 80% are an idea from a company outside of Sig, so there’s no customer support on a product they never made. For stuff like that you can approach someone like Sig80BitKits, they sell 80% and might help resolve issues.
@@SIGMECHANICS thanks for the information 🙏 I couldn't find it anywhere
Great video, yet it makes no sense to me when a good handgun with a manual safety can already be purchased. If a person is not sure enough of their ability to carry a handgun without a manual safety, why purchase one just to add a manual safety? I just would't buy a Sig p329 or a Glock.
Agreed, and personal preference and experience play a big roll.
It’s also possible it was purchased without knowing what models can and can’t have one. The Sig Mechanics MSAFE-T toolkit is an extremely popular tool now and I found that that people use it mainly because they like to have the OPTION to add a factory MS, not necessarily because they use it often.
? But how does any of this sophistication really account for the gun firing without the trigger being pulled. Noone with a brain can deny this isn't happening.
The video is not referring to the instances you’re talking about. It’s just to show the function of the mechanics behind it.
For all intents and purposes, to this day there is still not been anybody that can replicate the p320 discharging in the way that you are mentioning. Even with the case where the drop safety was found to be compromised, it was possible to easily replicate that scenario.
I’m not saying that it is impossible only that it’s not probable and that so far the only way to make the 320 discharge is by pulling the trigger a certain distance to disengage all the safeties internally.
If you’re interested, I did make a video that goes into more detail: th-cam.com/video/R0MpcFEXWhc/w-d-xo.htmlsi=VYW-eXLI4dUtEfPh
First
Sig p320s are junk.
Why exactly do you feel that way? Did you have a bad experience with one?
@@SIGMECHANICShe can't afford it.
Ha! No I just thought it might have been something in particular, I didn’t want to disregard his opinion if maybe I could clarify something.
Dude, you are junk.
