The SIG P320 likely suffers from a mechanical design flaw that, combined with the gun's modularity and varying tolerances, can cause uncommanded discharges.

“I think it's very low probability. I think because of the modularity of the gun and the tolerances and the different parts and the generations of the guns as times go goes on that the design has subtly changed in a few ways. You know, I think it it gets to a point where like the they the gun can be ”
