Well the shooting in Colorado got me thinking about this I must admit. I have seen the videos where the guy shoots himself point blank with a .44 Magnum pistol to demo his vest and nothing happens to him. Do people hit with body armor on even feel it? I carry a Glock 19, 9mm loaded with +P Gold Dots. This incident got me thinking about something bigger I must admit. I wonder if a hot 10mm or a hot .38 Super would effect someone in armor at close range. Some reports say the shooter was wearing a bullet proof helmet. So would a hot 10mm or .38 Super in the head have dropped him? All that energy has to go somewhere right? I'm not an expert in body armor so forgive my ignorance. I'm just curious as to what one can do besides a Mozambique drill, which in a dark, smoke filled theater with screaming innocent people running for their lives is not really a viable option. Thanks in advance.
