Sig P320 recall

[stevosmith]

I been reading the proposed recall for the sig p320 and it's still pending since 2014. sig does have fix but it's only a volunteer option not a mandatory recall from the factory.

so it seems like it can fire without a trigger pull, so meaning the firing pin is 100% cocked, with no hard safely, the firing pin can just slip out and shoot? or am i missing something.

my question to striker fire which I thought all striker fires are 50% firing pin cocked, then when using the trigger, it completes the other 50% to be able to shoot. so even though the firing pin slips out from a drop of the gun, the 50% cocked doesn't have enough force to hit the primer to shoot the bullet.

so just wondering if the P320 is 100% cocked unlike other striker fire?

Actually, what you're describing with the pistol at partial cock is "safe action." The only two companies/models that I know of that use that action are Glock and the S&W Sigma/SW9/SD9, but there may be others I am unaware of. The Kahr PM/CW series uses a full double action pull, similar to a revolver.

The majority of striker fired pistols are at 100% cocked. The P320 went off when dropped was because of two reasons.

1) The trigger doesn't have some sort of dingle to prevent it from rearward travel. Many striker fired pistols include a variant of a safety that prevents rearward travel unless deliberately placing your finger on the trigger.

2) The early P320 triggers were thicker metal and were heavy, carrying a lot of momentum. The voluntary upgrade replaces it with a lightweight trigger.

The original P320 would only accidentally go off when it hit the ground at a very specific angle because of the two reasons above. This is very apparent because, even if the firing pin slipped, the firing pin safety would prevent it from igniting the primer. When the pistol was dropped and landed on the rear of the gun, the trigger would continue to travel after the rest of the pistol stopped, emulating a trigger pull and disengaged the firing pin safety. This problem has been mostly negated now.

The rest of the stuff they did in the voluntary upgrade wasn't really to address drop safety.

can i assume all Sig striker fire are 100% cocked including the P365 new FSU?
