Another excellent video by “SIG Mechanics” showing how the P320 safety lever and safety lock work to block the striker if the trigger is not pulled.

No, no, no.

P320's spontaneously explode in the holster, maiming police officers six counties away, anytime the temperature changes, the wind increases one mph, or a bird sings. It's science.

Police wouldn't be allowed to sue Sig, if it weren't true.

Oddly, it never seems to happen to anyone else.

Very good video, though.

Great video, which clearly demonstrates what I've been saying all along regarding the striker safety and the fact that the trigger must be actuated in order to discharge the gun. Even with the pre-upgrade "firing-when-dropped" issue, the internal striker safety was behaving as designed, but the trigger was being actuated by inertia when the gun came into contact with a hard surface at the appropriate angle and velocity. The guns can't just discharge on their own without external forces acting on them
in a very specific manner.

Thanks for sharing this, Sigfreund. It has some great visuals and he does an excellent job explaining what is going on inside the gun.

Cool video. Thanks for sharing

Neat

I think we need to see how the FPS block reacts when not disengaged by the lifter but the striker under full tension is released and impacts the FPS block. Should stop it dead before the striker protrudes from the breach face.

BUT, let's say the stamping of that FPS block leaves some flashing or draft on the edge that engages the striker. Any ramping in the direction of the striker travel could cause the impact to push the FPS block out of the way. The FPS block should always have negative ramping to prevent this. The MIM striker geometry of the blocking ledge should be very consistent part to part, but the stamped lever can vary. It would take a defective part that is not stamped to print but it's conceivable.

For any gun involved in a "just went off" discharge, it would be simple to show that the mechanism works correctly and is not damaged or out of spec in a way to make what I described above occur.
