Back in 2021 I wrote the assessment just before I sold my 320. I shared it with some RUclipsrs of course nobody was a taker.: Two things you should look at more closely: 1). Striker assembly, specifically the integrated firing pin block. It is a flat piece of stamped metal with a 90 degree bend. The bend interfaces with the firing pin and not very deeply, might I add. Dirt/grime on that bend could prevent it from locking into the firing pin properly. Not a high probability, but an uncommanded discharge is a very low probability event. 2). Place the striker assembly back in the gun and reassemble it without the back plate. Then push the striker assembly into position and hold it there with your thumb. At the same time, pin the trigger forward so that it cannot move. Finally take a Glock tool and push down on the sear which is engaged with the striker. Your will find that the sear will release the striker. (Try this with a Glock = no movement of the cruciform.). At least this occurs with my copy which has gone back to Sig for the “recall” then a few months ago to fix some FTE issues. This tells me that if the firing pin block has grime in the right place, the gun can fire if it is jostled enough. It is also worth noting that the interface between the striker and sear is minimal, so dirt or grime there can make that connection weak. Bottom line is that this would be a super low probability event, but it is enough for me personally not to carry it.
I have been waiting for a gunsmith to tell me exactly how to check and perform a test to see this problem in action. I wonder if grinding a reverse bevel on the sear and the striker could make the lockup more reliable. Similar to AR milspec triggers where you can see the hammer actually reverse against the spring pressure by a few thousandths of an inch before the trigger "breaks". My milspec 1911s also do this thing. Thank you for this comment.
@@BigPhilsSaws a lot of the problem is that when the gun is in battery the sear can move down without the trigger getting pulled, that and the minimal interface between the sear and the striker. If you follow the steps I laid out, it’s very obvious.
@@rangehot I’ve never taken apart a 1911, but from what I remember the shelf of the 320 sear is extremely small. If the shelf was made to be bigger maybe the reverse bevel would help, but I think as it is, it won’t matter much given my assumption that the uncommanded discharge happens when there is filth in the area where the sear interfaces with the striker causing even less material holding the striker back. Another way to address the issue would be to make the firing pin block system more robust.
I have had three of them. Could not get comfortable with the trigger and the thought of the possibility of a "uncommanded" discharge, so I sold them. Good info in the video, thanks for posting!
I own 2. Been using one for official law enforcement duties and tactical training for over 6 years and trust my life to it. Have another I occasionally rotate in edc. I can understand the hesitation based on all the claims, misinformation out there, and some substantiated info. Every time I see this though, I wonder why Sig gets all this smoke and people sweep other major manufacturers issues under the rug and ignore the exploding pew issues. I won't throw the name out there but its heavily praised and almost a sin to bash them.
@love4gtsandguns well you have plenty of experience with the P320 and I am thankful you have not had issues. Is there a real issue? I don't know but would love to.
It's bad enough when manufacturers want us to be beta testers, but to keep selling a self firing pistol seems like a bad marketing decision in my eyes.
If the design wasn’t riding in our military’s holsters. It would be pulled off the market. If sig admits there’s a problem, uh oh, how do we explain this to the army. Can bet that contract would be terminated
The p320 also has a striker safety that disengages with initial take up of the trigger pull. If the sear or the part of the striker that engages with the sear were to break or malfunction without the trigger being pulled, the striker pin would not be allowed to enter the breach face and fire a round. So either the striker safety would also have to be broken when the sear disengages inadvertently, or the trigger would have to be pulled slightly by your finger, a foreign object, or a poorly fitted holster. If you feel uncomfortable with this, make sure you have a clean FCU, a well fitted holster, and for extra peace of mind you can swap the trigger to the Agency Arms unit with a built in trigger dingus safety.
Even if the striker slips off the search, there is a firing pin block that will keep the striker from hitting the primer unless it is lifted by a trigger pull. Just like with any other pistol with an internal block, so just coming off the sear isn't enough. Most likely, every unintended discharge is due to contact with the trigger...be it debris, ill-fitting holster, etc. If the P320 had a longer and heavier trigger travel and maybe even a safety dingus on the shoe like a Glock, a lot of these would probably have been avoided. But a lot of this was also happening with Glocks when they were first adopted by police. Difference now is that news spreads much more rapidly and sensationally. Interesting point about keeping the sear clean, but that alone isn't enough to fire the gun.
I agree with redesigning the chassis. Also most of the holster companies put out holsters fast to catch up with the new offerings. Sig in particular puts out so many variations of the P320, so size and fitment of the holsters are crucial. I stop carrying mine ( I usually carry appendix) but use it as my range firearm.
Sig is really avoiding a full buy-back, recall, or FCU replacement because it would be an admission of flawed design, and they would have to pay the plaintiffs.
Thinking about police officers having unintended discharges, I would like to know if there is any correlation of if these are veteran officers who have been on the force for a while or rookie officers who are new. I wonder if there's been something that officers have gotten accustomed to getting away with on other firearms that never caused a problem but when they switched over to the p320 and doing the same thing the 320s go off. Also the striker is putting resistance forward on the seer which is holding it back. Would that not help hold it in place from slipping off when it is not supposed to? And if there was having trouble fully engaging would that not show itself when firing on the range with some unintended double taps at least some of the time?
I use my M17 as a night stand piece so I'm less worried about this since it doesn't get the every day grime of carrying, but I will make sure to strip it down and give it a good clean after the next time I take it to the range (probably after I get a silencer for it).
That is exactly why I bought one. I erroneously thought that the testing had been done for me, which was why I was willing to pay the exorbitant price for an M18 and carry the thing. I put my faith in people who don't care about the safety of their marines, nor of American people. My mistake.
@therock1902 I have always liked it as the test sample I got from Sig was flawless. Once I heard about the couple issues I have been hesitant to keep it hot.
I think also tolerance stacking issues, caused by inconsistent dimensional differences in the MIM parts used in the FCU, is another contributing factor to this rash of in-holster uncommanded discharges happening with the P320.
@Stealth639 that is an excellent point. As tools are used they wear causing small dimension changes but still in spec. If you have enough parts at the cutting edge of in spec you wind up with an out of spec machine. Excellent thought my friend.
Thanks for your great insight on this issue. I currently own a P320 xcompact and a M18 w/manual safety. I’ve never experienced any of these issues and I do keep them clean. Question though, if I install a manual safety on the Xcompact? Will that alone illuminate any issues in the future when it comes to discharge issues? In your opinion of course…
I have been owning 2 p320s for yrs 1 is a subcompact no issues 2nd is a Xc mine stay loaded 24/7 they have never went off by themselves it’s the only brand I’ll ever carry
@ Yea I agree maybe I just got a good backchat ,I bought the subcompact when it first came out,But I see people hitting the back of the slide with a hammer just to see if it will go off or dropping it ,In my opinion those people shouldn’t even own a gun
@@StevenWDorn The P320 was not drop safe. People got shot because they dropped their pistol accidentally or tossed their duty belt into the back of their car or truck when they got off work and the vibration made the gun go off, resulting in serious injuries. People were doing videos tapping the back of the gun to demonstrate it was not drop safe. Those videos are the whole reason Sig began a voluntary upgrade program. Since that time, over 180 people have been injured because the p320 fired uncommanded in the holster. There are videos of it happening. Sig just lost a lawsuit and has to pay a guy 11 million dollars because the gun went off in its holster and injured the guy. An officer in La Grange, Texas had one go off uncommanded and almost killed him a couple of months ago. The P320 is not safe. Yours may not have gone off yet, but that doesn't mean much. You are carrying a ticking time bomb but hey, more power to you. Impress me and carry it AIWB. I'm just kidding, please don't do that.
Plenty of cctv footage showing uninitiated discharges in retention holsters. One officer in Texas getting out of his squad car and it goes off hitting his leg. Interesting theory on a potential fix. A report suggested that the military not carry with a round in the chamber on the manual safety m17/18
My uncle is a police officer in a major Texas city, they were all carrying X5 Legions until there were uncommanded discharges that resulted in casualties. Mostly from bumping the holsters on things like car doors but there were some that went off on the live fire range. Bumping a holster and going off means the sear slipped, on the range maybe the gun was dirty enough to impede the sear spring. They went with gen5 g45s with delta point pro optics instead.
I decided to get rid of all 3 i maintsin my guns but i no longer felt comfortable carrying it nor having my wife carry one sig should have gotten this taken care of i refuse to be a beta tester for them anymore
@@rangehot no offense but “most people” have no basic mechanical understanding let alone any real armors experience. The guns never go off on their own when out of the holster. They never fire more than 1 shot when the trigger is pulled. That alone should write off any theory about the striker “slipping” past not 1 but 2 sear ledges from debris.. the 320 cannot fire unless the trigger is manipulated.. Now “out of battery” type explosions.. that is a different issue and discussion..
Had mine for years did the fix on it then had the trigger lightened up I have had no problems at all and I carried it for 3 years till I decided to go with a smaller gun .
@@rangehot Yes. His opinion is wrong. Even if the sear slips, the gun will not fire unless the trigger is pulled. The sear and striker block would have to fail.
I said the same thing ..makes not a ton of sense cause the sigs out there now with safety plungers is 99% of them I'm guessing after the recall ..weird always seems to be in a holster ...
The primary issues with the P320 are: #1: Sig converted the P250 (DAO) to be striker fired, so it doesn't work all that well compared to a dedicated striker fired mechanism, like the P365. #2: The firing pin block is a thin, flimsy lever, NOT a cylinder. Very little pressure needed to disengage the firing pin block. On mostly every other pistol, the firing pin block is disengaged at the end of trigger travel. The P320 is disengaged upon takeup of the trigger....not good. #3: Poor holster compatibility. If ANY pressure is on the trigger in a P320 holster, the pistol is LIVE with a defeated firing pin block. Like having a 1911 with no grip/manual safety.....not good. The P320 works for me as a competition pistol, but I absolutely do not consider it a duty or carry gun.
@DanielEastwood25 can't argue with any of that. I wanted to love my p320, but the serialized FCU is its only redeeming quality. It's a mediocre platform at best. I think nearly all the unintentionally discharges are handling issues, but the trigger is certainly not as safe as other striker guns.
Sig knows what needs to be done. They knew about the major early issues that the Army dound during the MHS trials and testing. Sig put a bandaid to fix the immediate problem but not with the long term issues. Sig could put a passive trigger safety in the system to help cover most of the issues. Maybe they should go ahead and address the striker/sear engagement. They are a major manufacturer, so they probably don't want to admit the design is flawed and they know the fix because they don't want to be found liable for all of the p320's in current circulation. They have not figured out that sometimes the best way to regain trust is to admit a problem.
They were lazy engineering the pistol ,they took a P250 and jammed a striker fired FCU into it. I don’t buy Sig products even though they make some excellent firearms. I won’t support a company that does not take accountability for their screw ups
Sig "fixed" the issue. Lol! NOT! I refuse to be their beta tester! In September 2024, and November 2024 they were discharged on policeman again! Sig is bat shit crazy, in every single case they blame the user, saying they were being negligent! For that I will not buy another sig!
Sig P320 = Range Toy. Glock = Carry. After watching numerous videos my understanding is Sig 'doubled up' on the part(s) that block the sear. Yet the design is the same. Looked at logically this means its much less likely for both blocks to fail at the same time. But not impossible since they are both subject to the same failure rate. Bear in mind, someone wins the lottery every day. Odds are, it won't be you, but it might, and that's what keeps people coming back. Or like smokers. Some smoke for 40 years no problem. Some smoke for a year and die of cancer. Which will you be? Do you really want to take your chances just to find out?
If your worried just buy a aftermarket trigger with safety blade now there's 4 safety in the gun and 5 if its a m18 style lol...ppl shot themselves a ton in the 90s with gloscks when cleaning so I am thinking if you take out operator and holsters its almost like a lighting Strike in winter in Alaska
That’s really an accidental discharge. Most people confuse that with a negligent discharge. This type is a mechanical problem not involving any kind of negligence, that is unless you’re not following the 4 rules of gun safety when the gun decides to go bang. I agree with keeping that gun clean…..it ain’t no Glock or M&P 😊
@ I believe it’s a design issue but excessive maintenance would probably help cover up the problem. Grayguns is probably the best on Sig upgrades and mods. If there’s a simple fix, he would know. Glocks and M&P’s can and have went over 1000 rounds without cleaning. I clean mine just about every firing, but I enjoy working on guns 😊
@@rangehot no. I’m not an Sig guy. I like the old classic line like the 226, 229, etc, I just don’t think the polymer pistols have the same quality as the old ones did.
HAhahahaha 😂FYI-Sig claims this is NOT an issue and it's definitely the customer's fault!..... That's what Sig's doing! Lol even tho there's 20+ videos of the gun going off in a holster. I stopped carrying ANYTHING Sig after that, personally.
All this talk and literally zero hard evidence. No one has been able to give any mechanical reasoning or been able to replicate it. I don’t even own any sigs but no one has been able to give me any actual evidence of this stuff happening outside of one video of a cop using a jank holster.
Funny, not a single police dept. Laboratory, testing groups, engineers have been able to replicate the weapon malfuntion/defect after any p320 fired by itself. Seen to me that is only happens one time only and no one can make the gun fired uncommitted again. You guys sound like "that friend that only knows one joke" was funny the 1st time, after that......simply pathetic
If a weapon is firing holstered on multiple occasions that firearm needs to be pulled from production immediately. He’s right this has happened enough times it’s not a one off. A couple cops have essentially been medically retired from this. If you can’t 100% replicate it in a lab doesn’t mean you’re free to sell it and call everyone else conspiracy theories. If you sold a car that at random can accelerate to 100 mph on its own that car would be pulled from the streets until the problem is solved. Sig is a billion dollar market cap company, they can afford to fix the issue and forgo a bit of investor profit to protect peoples lives.

@@HVACR_ToolNut totally justified.
Sig P320 = Range Toy. Glock = Carry.
After watching numerous videos my understanding is Sig 'doubled up' on the part(s) that block the sear. Yet the design is the same. Looked at logically this means its much less likely for both blocks to fail at the same time. But not impossible since they are both subject to the same failure rate. Bear in mind, someone wins the lottery every day. Odds are, it won't be you, but it might, and that's what keeps people coming back. Or like smokers. Some smoke for 40 years no problem. Some smoke for a year and die of cancer. Which will you be? Do you really want to take your chances just to find out?
@lenzielenski3276 excellent points and I am in total agreement with you.
Great Video! This explains a lot. I really want to like the Sigs 320/365. Like the ergonomics but I don’t trust the track record.
@rona3150 thank you very much. Ever since I learned about these issues my P320 is range use only.
If your worried just buy a aftermarket trigger with safety blade now there's 4 safety in the gun and 5 if its a m18 style lol...ppl shot themselves a ton in the 90s with gloscks when cleaning so I am thinking if you take out operator and holsters its almost like a lighting Strike in winter in Alaska
You don’t hear about any problems with the Sig p250.
@stevemastbaum is it hammer or striker fired?
Hammer fire control unit.
That’s really an accidental discharge. Most people confuse that with a negligent discharge. This type is a mechanical problem not involving any kind of negligence, that is unless you’re not following the 4 rules of gun safety when the gun decides to go bang. I agree with keeping that gun clean…..it ain’t no Glock or M&P 😊
@@williamtoney2599 do you believe it is a maintenance issue?
@ I believe it’s a design issue but excessive maintenance would probably help cover up the problem. Grayguns is probably the best on Sig upgrades and mods. If there’s a simple fix, he would know. Glocks and M&P’s can and have went over 1000 rounds without cleaning. I clean mine just about every firing, but I enjoy working on guns 😊
Word to the wise, just don't. P320 is one hot mess.
@apstech4618 I have uploaded mine and it is range use only now.
Greyguns may have the answers….,
@@williamtoney2599 do you know offhand what that is?
@@rangehot no. I’m not an Sig guy. I like the old classic line like the 226, 229, etc, I just don’t think the polymer pistols have the same quality as the old ones did.
@williamtoney2599 I totally agree with you.
I have Berettas so I don't have to figure out why my gun is shooting me lol
@@maxximus2012 I understand
Poor sear engagement is why sig lost the recent lawsuit
@@62jape I heard the exact same thing.
Excellent information on the P320. I have considered one but now maybe not.
@@BarbaraElliot-g6h I would hold off to see how this plays out.
Incomplete sear engagement sounds very possible.
@@stevemastbaum that is what I am hearing.
People are lazy to clean their firearms, part of being gun owner is knowing your firearm
@jasonsosa1133 that is exactly true.
P365 FCU also susceptible to these issues?
@@Boneless_Chuck really? I did not know that.
For me that is a great observation. I have a psa and I always find lint after a few months
@@MichaelRoachDavid I have had no problems with stuff like that using leather holsters.
Not good!
P320 ... fire at any time ....
P320 is a waste of time and money.
There are other options without the P320 drama.
HAhahahaha 😂FYI-Sig claims this is NOT an issue and it's definitely the customer's fault!..... That's what Sig's doing! Lol even tho there's 20+ videos of the gun going off in a holster. I stopped carrying ANYTHING Sig after that, personally.
@@joshmajor8662 I think that is a good call.
It makes sense if there wasn't now safety plungers in 99% of site ...seems all are in holster which seems really odd in combo
It's mostly the dumb cops having these problems.
Your wrong there have competitions shooters as well. Also how is it a cops fault when it happems in the holsters your comment is dumb and uneducated
@@WalterLitwinko I don't think that is a fair or correct assessment.
And how come "dumb" cops don't have their Glocks going off for no reason, as well?
Such a poor design it becomes dangerous when dirty. So many other options out there to put up with that BS.
@@RFPews you are exactly right.
so it's junk
All this talk and literally zero hard evidence. No one has been able to give any mechanical reasoning or been able to replicate it. I don’t even own any sigs but no one has been able to give me any actual evidence of this stuff happening outside of one video of a cop using a jank holster.
@patriotplays6990 there are a number of videos of it happening.
Simple fix.... just buy Canik
@@edwardbiasi37 there is that. How about Colt?
Funny, not a single police dept. Laboratory, testing groups, engineers have been able to replicate the weapon malfuntion/defect after any p320 fired by itself. Seen to me that is only happens one time only and no one can make the gun fired uncommitted again. You guys sound like "that friend that only knows one joke" was funny the 1st time, after that......simply pathetic
@@JAC-l7m there are a few videos of it happening.
If a weapon is firing holstered on multiple occasions that firearm needs to be pulled from production immediately. He’s right this has happened enough times it’s not a one off. A couple cops have essentially been medically retired from this. If you can’t 100% replicate it in a lab doesn’t mean you’re free to sell it and call everyone else conspiracy theories. If you sold a car that at random can accelerate to 100 mph on its own that car would be pulled from the streets until the problem is solved. Sig is a billion dollar market cap company, they can afford to fix the issue and forgo a bit of investor profit to protect peoples lives.
@@wuldntuliktonoptb6861 if that was the case glock would have gone out of business.
