Sig P320 safety complaints

[9Cal_OC]

Well sig Changed the design and did a "voluntary upgrade" because they didn't want issue a official recall on their hottest gun to fix the problem and it's still happening so yes there is clearly a problem with the gun.

Is that still an issue with the new releases?

[BajaJames83]

No.

The early ones passed normal drop tests but when dropped at just the right angle they could fire.
As soon as it was found out SIG made changes to address it. Mainly which was changing the mass of the trigger which was the cause of the problem.

All of the incidents that have happened to date have not shown a problem with the firearm itself.
They all have shown:
Negligence (dont just put a loaded gun in your purse of gym bag not in a proper holster)
Improper equipment and or training. Just like glocks it is important to ensure your holster properly fits and the nothing is in there when you re-holster.

Many of these do come down to negligence and it is not a surprise these are happening to law enforcement and competition shooters.
Handling their firearm every day multiple times a day will often tuen into more of a chore and safety can go to the wayside for comfort or laziness.

Naw.... There is a fundamental design flaw in the 320 series. The full tension striker with a short trigger travel and interchangeable frames combined are a serious problem that make the 320 without a thumb safety dangerous.

I?m curious about the thumb safety. I don?t know enough about the design to know whether the manual safety prevents (whatever it is) from slipping off the contact surface. Do these issues all involve movement of the trigger? Is there another way to cause the failure in weird situations like it being torqued in a holster?

The thumb safety on the P320/M17/M18 only blocks movement of the trigger, it does not block movement of the sear.

I carry a P320 with no manual safety at work and off duty and have for several years, I'm not concerned.

But but some TrailerParkTrash says you’re risky depending your life on it

The concern has been duly noted and dismissed but it's good to know people care about others I suppose.

^^^ Hit’n the bottle a bit I see? I think I understood what you were trying to say there.

Anyway, my stance is worrying about shoot’n yer walnuts off with a P320. The striker is always “loaded” up. If dropped and the sear fails, there goes deez nutz.

Stock factory Glocks by design are literally incapable of going off even when dropped from high altitudes. The trigger must be pulled to the rear fully, in order for the internal safety mechanism to move out of the way, thus allowing the striker to do its thing on the primer. Not so with a Sig polymer piece of s***

M&P and XD both have fully cocked strikers. Do either of those have a spring loaded sear and striker that pulls themselves together for more sear engagement, nope. Do both of those have a half cock notch on the sear, again nope.

So for the 320 to go off with a sear failure when dropped, you would also need a half cock failure, and a fitting pin block failure. The likelihood of 3 failures at the same time is slim to none.

What will make the gun go off is if the trigger is moved. So if the gun is only going off while holstered, what's the common denominator? I've seen a large kydex holster make press in the trigger guard area so much the you can see the curve trigger outline. What if you weren't using a curve trigger? Holsters designed for WML are made wider at the trigger guard area in order for the light to be able to come out. That leads to the problem that something could get inside the trigger guard.

If the sear "fails" on a P320 and releases the striker pin, the striker pin will be blocked by the safety lock. The safety lock won't allow the striker pin past the breech face unless the trigger is pulled rearward. The Glock has a different design that does the same thing however they call it a firing pin safety.

Negative, guns manufactured after 2020 are bullet proof. The reliability and safety on the 320's are the same as Glocks.

[caliprep]

I?m fairly confident a gun discharging inside a holster has nothing to do with negligence or complacency. But I?ve been wrong before.

Possibly on the part of the engineer, or quality control?

Brotha, that video you're referring to has been debunked, and was neither a weapon's malfunction or AD. Search it up on youtube.

[GizmoSD]

Video? I?m talking about a holstered gun on a bench. We had another one of a guy sitting in a car.

It?s ok to say you like something just because you like something. There?s really no counter to that.

I think there is some confusion about "early" vs "current" production P320s. There's this false belief that the "current" guns are "safer". But this ignores the fact that any "early" FCU that has been to Sig for the voluntary upgrade is exactly the same as "current" production. The "current" production includes the "voluntary upgrade" as "standard". An upgraded FCU and current FCU are exactly the same, specifically, they have the exact same parts. They are identical.

Lots of really good information about what changes were made in the voluntary upgrade that are now "standard" in "post-upgrade/current" production.

And a great video showing the upgraded/current FCU to the "pre-upgrade" FCU. Anyone with a "post-upgrade/current" FCU can compare it to the video and see they are exactly the same.

The P226 is still a better gun, as is most of the P22X line. I am NOT a fan of striker fired guns. They have their purpose and many are considered safe but...

Nope. Legally Armed America did a video of his rubber mallet hitting the rear of the slide on that 320 and it went off. FAIL. Embrace the suck.

If that were the case, then Sig wouldn’t have 19 law suits now for the “POS”320, for going (((BANG))) without ever pulling the trigger.

If that were the case, Sig wouldn’t have had a horrible design allowing the gun to go (((BANG))) with a rubber mallet simply striking the rear of the slide.

Sig should have FIRED the designers of that crap gun.

Face it, Sig USA sucks.
