if you wanted to strike your threat with your gun, (for me it would be a glock 19) which part would you hit with? the bottom of the grip ( mag plate ) the slide? what would you do that would deliver enough energy to effectively knock out, concuss or disable the threat if only for short period of time? Just wondering what you guys would do if you were in that position and made that decision. I fear if i were to hold a threat at gunpoint, that he wouldnt take me seriously ( i have a baby face :\ ) go for his arm or weapon, or try to charge at me, and i would be forced to take him down. thanks for the input.
