I, myself, didn't pay enough attention to the recoil spring rotation placement, as the slide was not going back all the way upon reassembly, and it looked like the guide rod was being very awkwardly pulled in one direction when pulling the slide back. I had removed the recoil spring and guide rod, not paying attention to its orientation, and upon reinserting, I worriedly noticed some flat portions on the circular plate that I assumed went flat against the barrel. Wrong. If you look at the guide rod where it meets the barrel, there are two holes in the plate that holds the guide rod in place. Those holes should be vertical with gun, not horizontal, so quarter turn 90 degrees will get the barrel to properly reinsert and slide all the way back to lock. I found the answer "randomly" on SigTalk after someone had already helped OP. I probably should have read the manual.
Dude I had this problem before (when field stripping and not taking out the whole trigger assembly) and because I knew what few steps I did I was able to trace the issue back to the positioning or orientation of the guide rod…. So this time …. After taking everything out, trigger assembly and all, and having a tiny little rod fall to the floor when taking it out, I could NOT understand what I did and why it was not simply reassembling right so I could get the the slide to fit right again and get into lock position. I scrambled around and was about to give up until this commented reminded me…. :). What a weird issue. The whole guide rod never seemed right the first time I opened it. It looked like it wasn’t secure enough or could fail somehow easily
You saved my P320! I was ready to completely give up on the gun. I had trigger issues, mag would not seat all the way, and no trigger reset. All the same symptoms described. Thanks TH-cam for auto playing and recommending this video.
Thank you!!! I was heading to a gunsmith today to figure out the problem. I've never had a firearm do this. You just saved me some time and money. My sig is working fine again
THANKYOU!!!.I am a new gun owner and you explained the exact issue.I appreciate the way you held the 320 towards the camera,allowing me to pause and compare.YOU ROCK!!!
I just brought home my Sig AXG P320 Scorpion just released this month. Put a light on and removed the slide to install my matching RMR. Went to put together and the swearing started. Man if you lived in MN I owe you a dinner or a beer at the very latest. You have my heart felt thank you!!!!!!!
Highly useful video, thanks for posting. I observed this with a new Sig M17 that the pistol can be put back together in such a manner where the trigger will not engage. The position of the takedown lever is important to avoiding this. I find it helpful to retract the slide all the way and engage the slide stop before rotating the takedown lever back into it's horizontal position. It is a very nice shooting pistol.
Yup just got me one of those beautiful m17's first time cleaning it I thought I broke the damn thing. Nope... should have just followed the directions 🙄
@@URBJK totally agree. My p320 is going back to Sig for the 2nd time. After coming back the first, I cannot field strip the pistol without pulling the trigger. Something is amiss. Also, under stress this video proves that it's very easy to reassemble the pistol into a paper weight. No thanks. I have a P226 thats a beauty but shoots like crap. P320 shoots well but just aint right. My friends MPX is about the only thing by Sig that I am truly impressed with. Oh and their customer service sucks.
Thank you so much! I just bought a Sig P320 X5 Legion and after putting the FCU back in I had the take down lever in the wrong way and the safety went into place and I could not even put the mag in. I reassembled it watching your video and voila!. Thank you so much!
THANK YOU. I was about to send it back to the manufacturer for maintenance. The first couple of videos suggested it and only acknowledged it was a problem
Thank you so much! I just brought an X carry home, switched out the grip module for a Wilson Combat and ended up with a dead trigger. I thought i i broke something. You video put me on track. All good. Thanks again!
To simplify what to do when you find yourself in this condition. Just lock the slide back. DONE> It fixes it right then and there, you don't have to take it apart again.
Thank you. It's not an intuitive fix, but very simple, and a relief. This is a new gun, and thought it might be defective. Have several semi-auto pistols but never had an issue reassembling. Appreciate the post.
I've also noticed on my full size, that if the takedown lever isn't inserted all the way into the FCU the same thing happens. if it's not right up against the grip module, sticking out like a 1/16th of a inch this happens. make sure the takedown lever is inserted the way in the firearm before rotating countercloclock wise back to it normal position.
Yep. I did the same thing and I had reassemble dthe thing a couple dozen times previously with no issue. Thought something was broke, or I'd broke something but finally but eventually figured it out. Then, of course, I find this old video that explains it perfectly. Great explanation and I concur...there's no way you won't know that you've done this.
Awesome video.... you get straight to the point where others having the same problem are bewildered. Its user error not gun error In the guy that says this video sold another Glock He's totally missing the point and doesn't comprehend the video at all This is a praise to Sig about having built-in safety features Put the gun together safely the way Sig told you to do it and you won't have any problems
Thanks! I have had this problem. When new the take down lever is VERY tight. Also, narrow end of the oval shaped the recoil spring guide has to be vertical not horizontal. There are small holes in the face of the oval position them up ward.
I JUST got my Sig P320 not even 30 minutes ago and the same thing happened to me, I watched the other guys vid first. THANK YOU SOOOO MUCH for this info.
It's my pleasure. There is a lot of excitement and discussion about the P320 around the internet that can be a great source for information. There is a "SIG Sauer P320" group on Facebook that has been particularly active and useful in addition to the SIGForum.com and SIGTalk.com. Good luck with your new gun. I am loving all three of the P320s that I now own.
Alma Cole I am on sigtalk but will be joining the FB page too. I think I need the smaller grip, I got notification of them being in stock but by the time I made it home it was already sold out.
Thanks so much for this video, was having trouble switching over to the X5 frame on my full size P320, this helped me fix the fact that the trigger would not work in the new frame. Much appreciated
Thanks, Alma! All these years of owning many 320's and this is the first time this issue cropped up for me--and again, here you are to save the day! :)
Thank you for posting this video. I was going crazy trying to figure out why it won't fire and figure there is a trick. I will always lock the slide back to disassemble and reassemble and make sure the lever is all the way down.
So, I'm cleaning my 320. Concealed carry class in a few days. Exactly, what you showed in this video just happened but after watching you SUPERB tutorial I was able to make it function again. Before I saw this I lamented I'd have to use my sh1tty G43 in the class. Thank you x1000, dude.
Great video Alma. Once people understand how the FCU and all of it's components actually function, they sooner they will understand that this is not a problem, but rather a part of the built in safeties of the platform.
Yep, I did the same thing. I finally figured it was that way by design when I flipped the slide release and I heard it disengage. My wife asked do you get a broke gun? I said no, this has to be ok I just shot the damn thing. I did see that lever and realized that was the reason the mag would not go in and I WAS reassembling my weapon wrong to cause that.
Man, I know I'm late to this party, but for the last 15 minutes, I have been flabbergasted. I went from a Glock 20 to my current P320/M17 and had just disassembled for the first time. I put it back together and ran a dry fire function check sans magazine, and noticed something was off with the trigger reset. I was getting a VERY minor, and barely audible, click, with no feeling behind it. So I tried and tried again, with the trigger/firing mechanism obviously not setting correctly. I disassembled again and found your video. Right as it started, I reassembled only to have it working, but had no clue what I'd done differently. Finished your video anyway out of curiosity, and that HAD to be my issue, no question about it. Guess my Sig is a bit more anal regarding reassembly than the Glocks were! Anyway, I appreciate the insight, hopefully I can avoid the issue going forward.
Might have bent the trigger return spring. I think I cover that in a separate video Might be able to bend it back so it's 90 degrees when sitting flat, off of the gun.
@@AlmaCole Things are pretty much perfect now, so I shouldn't be dealing with anything like that. Hoping I just screwed up how you mentioned here, and would have noticed had I actually inserted a magazine prior to function. Tomorrow is range day, so I'll certainly head back and check out the other video if I run into an issue, but I do believe things are peachy. Appreciate the response, good lookin out!
Late to the party (Komifornia is finally getting p320s). Appreciate the video and info, this solved my problem. Like so many... user error! Appreciate it man!
Wow, thank you for this video, i had no idea about that little tab down there. I put on a new aftermarket slide and installed my internals, put the FCG in a wilson combat lower and it wouldnt fire. Took the slide off and played with the slide stop until it clicked. now its functioning again. LOL
I had the same problem when I first cleaned my gun,I could not figure out why the magazine would not go in the gun then I realized you must push up on the slide release when engaging the slide back onto the gun, then you can rotate the takedown lever back in its original position in the gun is good to go
Why does the take lever take so much effort to rotate compared to my P226, I now carry a small pair of channel locks in case I need to take it down during a competition or range trip? Great videos from disassembly to assembly. Thanks Greg
Wife got me the Sig P320 for Christmas (She did her research and was aware of the voluntary recall). When I disassembled the P320, The first thing I noticed was the magazine not seating after reassembly. I did check the Sig website to see if this was part of the recall; which it wasn’t. Then I found your video which definitely cleared up the issue. I do have a quick question that perhaps you could answer. when “reassembling” I noticed that the sear catches (pops up) on the upper when “sliding it back!” Is this common and or is this part of the recall to fix that issue. Either way I generally have to finesse it back, I see it being an issue in a dire situation and or causing damage or possibly breaking the sear. Thanks in advance for any input.
Great video. I found that when I do this by accident, all I have to do is cycle the slide while holding the slide lock button. Then releasing it and the tab pops back into its place.
To simplify what to do when you find yourself in this condition. Just lock the slide back. DONE> It fixes it right then and there, you don't have to take it apart again.
great video, but still can't figure out what you're doing around 4:43 that lets the slide come back all the way. my P229 didn't do this. I follow you right up until you put the slide back on then...yours glides, mine stops.
Another thing worth noting, some build kits were shipped out with 1 of the 2 sear springs missing. I was able to order one from sigsourparts. I would also suggest everyone working on the FCU and small parts use a magnetic tray for all the bits and pieces. (The pins and springs) They're so small and very easy to lose. Anyone with experience building receivers who's dropped a detent or spring knows exactly what I'm saying. Carpet will eat them and tile or concrete will bounce them into another dimension. Really. Last thing, the very bottom back pin that holds the safety/sear housing in the FCU/MUP fell out for the second time and is now missing. Be aware of all the pins/springs etc if/when you pull the FCU from the grip module. Don't want a vital part falling out or off the system causing a failure or even worse an injury to the shooter or bystander. Phenomenal weapon and overall a relatively easy process from start to finish. I found the JSD Supply 3D animated AutoCAD videos to be the most concise and practical for myself, which were the only ones available back when I was doing all this anyway. Truthfully they're easier to follow than the more recent ones people are posting with all their commentary and fumbling/bumbling lol.
To simplify what to do when you find yourself in this condition. Just lock the slide back. DONE> It fixes it right then and there, you don't have to take it apart again.
This helped so much but it was one of the pins in the FCU that was not pressed in all the way into the other side of the FCU. Once I pressed the pin all the way into the other side, the little metal tab piece was able to click or go back into that little hole you pointed out. Hope this helps someone else
So I am very excited to see this video but either I'm overlooking something or my issue goes further. Every time I move the takedown lever it immediately pops the safety back. I can't find a way to reassemble while keeping that little tab where it's supposed to be
Guy Diesel did you ever figure it out? Just bought my Sig a week ago, shot a few hundred rounds out of it flawlessly. Took it apart to clean it... now I'm having the exact same issue!
When you are dry firing with the slide off and said it's a unique feature to P320, it seemed as of the sear drops once the trigger is depressed beyond a certain point, just like a double action hammer, but on mine, the sear doesn't pop back until I release the trigger. Am I seeing it correctly on your video??
I had the p250 before the p320. The p250 doesn't require the slide catch be engaged on reassembly. Just push the side back far enough to rotate the takedown lever and good to go. It didn't take long to figure out that didn't work on the 320.
My pelt2 trigger, if I rotate and remove slide, if I pull the trigger it will not reset. And if I pull the trigger forward it will have a heavy friction. I have to lift the slide lock up then something clicks and trigger works perfectly. Gun works fine as long as I don't pull trigger with slide off..have no idea what is causing that
Thank you I accidentally pulled the trigger on mine while cleaning the gun and wiping down the trigger guard and this happened or it was a coincidence either way you saved me...
I recently bought a P320, took it apart, cleaned it, reassembled, and had this issue. My concern is it seems to have changed the feel of the trigger. I remember the trigger being crisp and clean, which it still feels if I use the trigger without the slide on as you showed. When the slide is on it feels mushy and I can physically see the slide moving around when the trigger breaks. Is there something else that I may have effected by reassembling incorrectly?
+keener713 Try inserting a magazine with a snap cap and then dry firing. The magazine removes much of the play between the slide and frame. If you removed the triggerbar spring it's possible that you could have deformed the triggerbar spring. Instructions on what it should look like can be found here th-cam.com/video/jmflAN180dc/w-d-xo.html
+Alma Cole Unfortunately Academy doesn't carry 9mm snap caps, just every other major caliber. I didn't take the triggerbar spring off and the spring doesn't look bent. I messed around with it some more and put the fcu on the slide without the grip and the trigger felt perfect. However I did this again with the takedown lever installed and it felt mushy again. I'm gonna take it to the store I bought it from tomorrow to see if they have any idea.
Put mine back together properly. Trigger is really crunchy on takeup. Almost like a 3 stage trigger now. When I pull the slide back, it feels great. No grit on takeup. Any ideas? Also, the takedown lever is near impossible to move. My fingers are bleeding. I try to manipulate the guide rod, but doesn't make it much easier.
Do you have the Bruce gray fat guide rod? Ever since I've got that rod my slide stop won't lock when re assembling. I have to hold the slide back and hit the slide release while holding the slide back
I found another way to fix this issue because I just got a 320 and was sure I broke it and was anxious to say the least. On the new slides (2022) at least they a have notch halfway down the slide you can hit the slide release up when you have your slide half back like a press check and you’ll hear it click out of the way and you’re good to go
What about if I can insert a magazine but the trigger still doesn’t engage. I am using a pre-drop safety 3.9” slide on an X Compact medium grip module.
This happens when someone tries to reassemble it without locking the slide back first before rotating the take down lever. That procedure hasn’t changed for any P model. Honestly not sure why people think its a ‘stupid’ design. The purpose for the drop-in fire control unit was for modularity. Not so someone can save a few seconds from field stripping and reassembly.
I've a brand new Sig P320 full size. The take down lever is so hard I have finger cuts and blood blisters trying to take the slide off and yes I know the correct method. I'm going to Sig on the issue. I'm waiting for the takedown lever to break with the force necessary to try to take the slide off. This is Sig quality ??
Yes thank you. I tried all that and to no avail. Peculiar. I've sent it back to Sig for them to figure out. Probably a simple fix or a replacement on the take down lever. Who knows. Thank you for this video. It's a great help.
I have one for you - my recoil spring broke and I cannot pull the slide back far enough to remove it. The spring is jammed in and I don't know what to do to take it apart.
Great video, very informative. I just disassembled/reassembled my p320 compact after her first day at the range and followed all your instructions. Everything seems fine but when I dry fired it for the first time and the trigger pulled but didn’t have the same sounding click...I sounds a little dull (if that makes sense). Like a wonky spring sound. I’m nervous about firing with live rounds. Am I overthinking it?
The very 1st thing you did when you pull the slide forward to disassemble it. I did the same thing to my P320 and when I went to reassemble the guide spring wouldn't go in all the way. What happened?
I tride that and the take down lever keeps pushing the slide release tab out and I cant insert the magazine. What am I doing wrong can I just grind the tab of of the slide release?
Bought the gun brand new and the slide ain’t even on right it’s sitting a little back and I had that problem but still don’t know how to get the lever front if it’s still blocking when the slide back on. So when I get the slide on it’s blocking the magazine so the mag now doesn’t fit
Can I ask what sights you are running on that? I love the rear look on yours, if you know the brand or type and # that would be awesome. or atleast point me in the right direction. Thanks!
I, myself, didn't pay enough attention to the recoil spring rotation placement, as the slide was not going back all the way upon reassembly, and it looked like the guide rod was being very awkwardly pulled in one direction when pulling the slide back.

Exactly, if you cant get your slide back all the way, this is the reason. Rotate spring assembly 1/4 turn.
thank you I was getting annoyed lol

This is a perfect example of why you function test your guns after reassembly....especially one you're counting your life on.

I feel like a dumbass. I’m usually all good with my reassemble. But this scared me with my p320 now I got it! Thank you!!
And the key to those that didn’t pay attention is lock the slide open before you turn the lever then unlock the slide with the slide release.
Thank you, this just happened to me and you are the only one who has it!!!
Excellent video, I myself had this very problem that’s why I looked up the topic and woo hoo. Subscribing now.
Why does the take lever take so much effort to rotate compared to my P226, I now carry a small pair of channel locks in case I need to take it down during a competition or range trip?
Great videos from disassembly to assembly.
Thanks Greg
Great video and explanation. Very much appreciated.
This video saved my bacon I appreciate you taking the time to teach us all
Thanks I'm frustrated to why my trigger wasn't working , I knew someone smarter than me was out there to help.
Thank you…this video helped me “fix” my M18
Wife got me the Sig P320 for Christmas (She did her research and was aware of the voluntary recall). When I disassembled the P320, The first thing I noticed was the magazine not seating after reassembly. I did check the Sig website to see if this was part of the recall; which it wasn’t. Then I found your video which definitely cleared up the issue. I do have a quick question that perhaps you could answer. when “reassembling” I noticed that the sear catches (pops up) on the upper when “sliding it back!” Is this common and or is this part of the recall to fix that issue. Either way I generally have to finesse it back, I see it being an issue in a dire situation and or causing damage or possibly breaking the sear. Thanks in advance for any input.
Yep happened to me too, reassembled 50 times now and no issues, then one time and I’m like wtf, thanks for the fix
Great video. I found that when I do this by accident, all I have to do is cycle the slide while holding the slide lock button. Then releasing it and the tab pops back into its place.
Can not thank you enough, 2 days of pulling very thing apart and puzzled.
Thank you. I had the same stupid problem yesterday. That kind of problem didn't happen with my other 17 pistol of different maker. What a shame.
Thank you, I had this very problem and your solution worked.
Thank you. I was disassembling my XCarry, and the trigger went dead. Pulled up on the slide release and sure enough it works now.
To simplify what to do when you find yourself in this condition. Just lock the slide back. DONE> It fixes it right then and there, you don't have to take it apart again.
I did that just before reading this comment haha
Thank you !! I bought a 40sw xchange kit and was having trouble putting it together for 5 hours.
great video, but still can't figure out what you're doing around 4:43 that lets the slide come back all the way. my P229 didn't do this. I follow you right up until you put the slide back on then...yours glides, mine stops.
Another thing worth noting, some build kits were shipped out with 1 of the 2 sear springs missing. I was able to order one from sigsourparts. I would also suggest everyone working on the FCU and small parts use a magnetic tray for all the bits and pieces. (The pins and springs) They're so small and very easy to lose. Anyone with experience building receivers who's dropped a detent or spring knows exactly what I'm saying. Carpet will eat them and tile or concrete will bounce them into another dimension. Really.
Last thing, the very bottom back pin that holds the safety/sear housing in the FCU/MUP fell out for the second time and is now missing.
Be aware of all the pins/springs etc if/when you pull the FCU from the grip module. Don't want a vital part falling out or off the system causing a failure or even worse an injury to the shooter or bystander.
Phenomenal weapon and overall a relatively easy process from start to finish. I found the JSD Supply 3D animated AutoCAD videos to be the most concise and practical for myself, which were the only ones available back when I was doing all this anyway. Truthfully they're easier to follow than the more recent ones people are posting with all their commentary and fumbling/bumbling lol.
This was very helpful and well explained
This was the exact issue I had when reassembling my Captain's weapon, now I can look smart when he comes to inspect it tomorrow.
To simplify what to do when you find yourself in this condition. Just lock the slide back. DONE> It fixes it right then and there, you don't have to take it apart again.
I disassembled it wrong everytime and never figured this out thank you so fucking much m8
You're a goat dog. Hearting a comment from a 7 year old video... legend sending love from the communist state of nj ❤️ 💙 ♥️
thank you taking the time to make this video, great help
This helped so much but it was one of the pins in the FCU that was not pressed in all the way into the other side of the FCU. Once I pressed the pin all the way into the other side, the little metal tab piece was able to click or go back into that little hole you pointed out. Hope this helps someone else
Thank you for this......was exactly what I needed to know
So I am very excited to see this video but either I'm overlooking something or my issue goes further. Every time I move the takedown lever it immediately pops the safety back. I can't find a way to reassemble while keeping that little tab where it's supposed to be
Guy Diesel did you ever figure it out? Just bought my Sig a week ago, shot a few hundred rounds out of it flawlessly. Took it apart to clean it... now I'm having the exact same issue!
I’m having the same reoccurring issue too and this is what is happening to mine but this solution doesn’t fix it.
More info to digest and move forward in my purchase of one! Thanks!
It was very helpful thank you I thought I had broke something inside
Fixed mine! Many thanks!
When you are dry firing with the slide off and said it's a unique feature to P320, it seemed as of the sear drops once the trigger is depressed beyond a certain point, just like a double action hammer, but on mine, the sear doesn't pop back until I release the trigger. Am I seeing it correctly on your video??
I had the p250 before the p320. The p250 doesn't require the slide catch be engaged on reassembly. Just push the side back far enough to rotate the takedown lever and good to go.
It didn't take long to figure out that didn't work on the 320.
My pelt2 trigger, if I rotate and remove slide, if I pull the trigger it will not reset. And if I pull the trigger forward it will have a heavy friction. I have to lift the slide lock up then something clicks and trigger works perfectly. Gun works fine as long as I don't pull trigger with slide off..have no idea what is causing that
Thank you I accidentally pulled the trigger on mine while cleaning the gun and wiping down the trigger guard and this happened or it was a coincidence either way you saved me...
I recently bought a P320, took it apart, cleaned it, reassembled, and had this issue. My concern is it seems to have changed the feel of the trigger. I remember the trigger being crisp and clean, which it still feels if I use the trigger without the slide on as you showed. When the slide is on it feels mushy and I can physically see the slide moving around when the trigger breaks. Is there something else that I may have effected by reassembling incorrectly?
+keener713 Try inserting a magazine with a snap cap and then dry firing. The magazine removes much of the play between the slide and frame. If you removed the triggerbar spring it's possible that you could have deformed the triggerbar spring. Instructions on what it should look like can be found here th-cam.com/video/jmflAN180dc/w-d-xo.html
+Alma Cole Unfortunately Academy doesn't carry 9mm snap caps, just every other major caliber. I didn't take the triggerbar spring off and the spring doesn't look bent. I messed around with it some more and put the fcu on the slide without the grip and the trigger felt perfect. However I did this again with the takedown lever installed and it felt mushy again. I'm gonna take it to the store I bought it from tomorrow to see if they have any idea.
Put mine back together properly. Trigger is really crunchy on takeup. Almost like a 3 stage trigger now. When I pull the slide back, it feels great. No grit on takeup. Any ideas?
Also, the takedown lever is near impossible to move. My fingers are bleeding. I try to manipulate the guide rod, but doesn't make it much easier.
Thanks for this video. Definitely saved my dealer an ass whoopin! Lol
Do you have the Bruce gray fat guide rod? Ever since I've got that rod my slide stop won't lock when re assembling. I have to hold the slide back and hit the slide release while holding the slide back
Yes. I use those extensively. No issues with any of mine. Strange.
I found another way to fix this issue because I just got a 320 and was sure I broke it and was anxious to say the least.
On the new slides (2022) at least they a have notch halfway down the slide you can hit the slide release up when you have your slide half back like a press check and you’ll hear it click out of the way and you’re good to go
Damn I didn’t think I’d get the content creator to like this. That’s awesome.
What about if I can insert a magazine but the trigger still doesn’t engage. I am using a pre-drop safety 3.9” slide on an X Compact medium grip module.
Thanks for the video!!! It really help!
This happens when someone tries to reassemble it without locking the slide back first before rotating the take down lever. That procedure hasn’t changed for any P model.
Honestly not sure why people think its a ‘stupid’ design. The purpose for the drop-in fire control unit was for modularity. Not so someone can save a few seconds from field stripping and reassembly.
Pull your slide back halfway like a press check and push the slide release up on that extra notch cut on the sides for it to clear this malfunction
I needed to see this! Thanks.
I've a brand new Sig P320 full size. The take down lever is so hard I have finger cuts and blood blisters trying to take the slide off and yes I know the correct method. I'm going to Sig on the issue. I'm waiting for the takedown lever to break with the force necessary to try to take the slide off. This is Sig quality ??
Walter Palmer lock back the slide and try moving the guide rod up or down, then try the takedown again.
Yes thank you. I tried all that and to no avail. Peculiar. I've sent it back to Sig for them to figure out. Probably a simple fix or a replacement on the take down lever. Who knows. Thank you for this video. It's a great help.
Walter Palmer So, a year later, what did they find?
Just had this happen...great video and great relief...I thought I'd FUBAR'd it...LOL
I have one for you - my recoil spring broke and I cannot pull the slide back far enough to remove it. The spring is jammed in and I don't know what to do to take it apart.
Great video, very informative. I just disassembled/reassembled my p320 compact after her first day at the range and followed all your instructions. Everything seems fine but when I dry fired it for the first time and the trigger pulled but didn’t have the same sounding click...I sounds a little dull (if that makes sense). Like a wonky spring sound. I’m nervous about firing with live rounds. Am I overthinking it?
I’m still having the issue, can put the mag in but doesn’t fire... bought a different slide, but it’s a P320!!! Would that matter??
The very 1st thing you did when you pull the slide forward to disassemble it. I did the same thing to my P320 and when I went to reassemble the guide spring wouldn't go in all the way. What happened?
So I lifted up and it shifted that tab a little but still not enough to seat a mag… what else can I do?
I tride that and the take down lever keeps pushing the slide release tab out and I cant insert the magazine. What am I doing wrong can I just grind the tab of of the slide release?
Just had this problem. Ty sir.
Awesome video, thanks for the information
Bought the gun brand new and the slide ain’t even on right it’s sitting a little back and I had that problem but still don’t know how to get the lever front if it’s still blocking when the slide back on. So when I get the slide on it’s blocking the magazine so the mag now doesn’t fit
Can I ask what sights you are running on that? I love the rear look on yours, if you know the brand or type and # that would be awesome. or atleast point me in the right direction. Thanks!
Those are Dawson Precision sights
@@AlmaCole Thanks brotha!
@@AlmaCole you like those alot more than the ones that came stock?
Bro you’re a god
