Wyoming Gun Project has released a video (below) that showed repeated success in getting the Sig P320 to discharge by rocking the slide ... provided that the trigger was held back to the "wall" just before the trigger break, which he does through the simple expedient of inserting a screw between the trigger shoe and the frame. I've since seen a couple other videos from other YouTube channels that have accomplished the same by holding the trigger back slightly before applying forces to the slide.
Apparently the movement of the slide is enough to force the lever/connector that releases the striker up just enough to let it go (see the second video below showing how the trigger mechanism works). (Sorry, but I don't know the specific terms for the parts). And while I can see that working when 90% of the travel has already occurred with the trigger being pushed back to the wall, does it explain discharges where the pistol is in a holster and nothing is impinging on the trigger and pushing it back near to the point of trigger break? I don't know.

And some parts come from India. Hmmm.
ReplyDeleteThat would explain it. India couldn't even develop its own working assault rifle.
