+1 CombatArmsUSAF I had M9 training with the Air Force and everything was just as you stated. Of course you can't totally idiot-proof something - one of the guys in my class managed to shoot his guide rod halfway across the room and hit someone else with it while field-stripping his Beretta. However, the real danger in the CCW class we are discussing is that lack of control over where the firearms are coming from, whether they are loaded, whether or not they have been checked etc. before dry-firing. As Chris Rock once said, "We don't need gun control, we need bullet control!"
