Does the p320 go off if it's smacked still?
I know some of you Sig fluffers will tell me it was never a thing, but I saw a video once where a guy hit the back of the slide with a hammer a few times and it went off so yes it was indeed a thing for the sample size tested.
I have a concept in the initial brainstorming phase for two handguns connected by a cable to be swung wildly and think the unpredictable effect of discharge will enhance the capability.
Sig Mechanics on YouTube has some great videos about the internal mechanisms of the P320. This video specifically covers the pre/post "voluntary upgrade" changes.
