Sig P320 safety complaints

[tomk556]

IMHO, this is the real question that no one has been able to answer. There's a lot of talk about fully cocked strikers, but that in and of itself doesn't completely explain how the gun could fire by itself. Some how the striker slips off the sear. But how? No one has been able to offer any explanations of how this happens. Other than something getting in the trigger guard and unintentionally depressing the trigger, which is user error.

Exactly. And defeating the striker safety takes considerably more than just slight trigger movement.

I agree- for the failure to occur it basically needs to slip past two sears and then past the striker block. It?s entirely possible there?s an issue- I don?t really buy the mallet example but it would have to be a strange force like that- maybe from the magazine- that would both bump the striker off both sears while also bumping the striker safety up. I also wonder if it could be something like the grip, and thus FCU, being torqued slightly away from the slide. Or maybe it?s just the hype? if there is an issue hopefully the solution is a relatively simple redesign of the striker or a change in material etc.

I will say too that if Sig is saying some of these pops are due to improper holster use like the recent lobby one I am highly skeptical of that. I definitely don?t see how a pistol otherwise retained by the ALS system would be susceptible to trigger movement just because the retention loop was supposedly not in place.

You are actually reinforcing my point. All those complicated movements in the FCU could just be the problem by it's very design. Obviously, it is not happening with every gun, but consider carefully what I'm suggesting: the simple combination of a complicated system, tolerances, engagements surfaces, etc may possibly be combining to create the problem, where just one of those issue by itself wouldn't necessarily be a cause for alarm.

I only made the comment about light shocks etc because we all know about the "Glock bump" where if you slam in a magazine with just the right force, or just the right way, the slide will go home and heaven help you if your finger is on the trigger when it does...the possibility of creating a slam fire gets to be a bit chilling. Again, I point to the complicated action of striker guns and the small bitty little parts in them that might just be catching up with the industry. I mean...how much more complicated can we make it before the parts become so micro sized that it's just unsafe to handle?

I don't buy the "bad holster handling" comment either. If that were the case, they'd be able to point to that, especially if it happened multiple times where the same holster figured prominently. That would be too easy.

That?s an interesting point. I?m mostly familiar with Glocks as a point of comparison and have been reading about the 320. Playing around with the 320 FCU it does seem like there are more small, thin (I don?t want to say flimsy) parts. I suppose that?s relatively true of Glock also. The striker is definitely a lot more complex on the 320.

Meanwhile out of about 1,500 round I?ve had two failures to feed. I pulled the mag it happened with out of circulation to see if it persists. Ironically happened after I had done a detail strip and cleaning?

I feel ya. I just detail stripped a friend's CZ 75 with a decocker. The sear cage has 8 parts total to it and the entire thing assembled is about 3/4" x 5/8" or so. There's one tiny little sear spring that is literally hair thin, has two coils around a 3/16 pin and from tip to tip is about 1/4". It can go in backwards, too.

When I took the gun apart, the sear cage fell apart and I had to spend nearly 90 minutes looking for that damn spring. Now I have to call CZ to make sure I put it in correctly, because it can apparently function even reversed but I'm not handing my buddy back his gun put together wrong. All of this on a hammer fired pistol.

Sig has been very transparent about the changes they made to the P320 including replacing the sear. See the video above that I posted, which is from the Sig website. They've posted this information on their own website for anyone to easily find.

Quickly making changes to enhance safety is a good thing.

You are being overly emotional about the P320. It may have issues but while others are being objective and unemotional, you are really going off on it like you have a personal grievance against Sig, which just isn't rational.

“Emotional?” ”Personal grievance?” Well, you’re sorta right. But not even 1/10th as emotional as the people that actually experienced mystery BOOMS from those pieces of s*/+ and without ever pulling the trigger. Sig P-series of polymer junk pistols are made in the same factory where Harbor Freight brooms, screw drivers and duct tape are made. Some people are obviously good with that.

I take it by your comments that you’re very accepting and tolerant with those CONTINUED incidents of Sig auto-discharges as well and the fact that neither Sig nor anybody else admits as to the exact cause of the issue. Has the issue been fully resolved? Nobody knows for sure and Sig gives rediculous answers like Kamala Harris talks about border security. It?s not very comforting, especially when the gun is carried AIWB and pointed at one?s junk.

My agency has all Sig P320's with no manual safety and we have not had any of these problems. That's not to say that there aren't problems. I also remember us being forced to change duty holsters when we had Glock 22's because there was a gap large enough that someone could ND the gun during the draw stroke if they weren't paying attention. These were Safariland duty holsters with ALS retention.

All that being said, I have my duty gun that I carry and a backup P320SC with manual safety and I generally don't worry about either. Rumor is that we may switch guns again next year, and if we do, I plan to buy my 320.
