Lucky guy he is, the one who beat up the mugger supposedly. Lucky that the mugger's trigger reflex is bad enough to allow him(mugger) into a position to be beaten up! Otherwise, there'd be a bit of brains on the sidewalk! Don't get too overzealous kids, bullets are really hard to dodge!
Naww, if you're trained and you know what you're doing it's pretty easy to disarm someone, especially if that person isn't expecting it. Don't forget, that sort of stuff is 250's job. I agree that it probably wouldn't be a good idea for you or me to try it, though.
