This is why you don't wear guns in a manner that points the bullet at your body or your horse. The SIG P320 did have an automatic fire feature that apparently could work because the firing pin was under tension and could move independently of the trigger mechanism. This is unlike a Glock system that won't let the firing pin move rearward unless the trigger is pulled rearward.
