i hope my opinion didn't cause any trouble; i have never been in a gunfight with anything but a whitetail, so i can't speak authorativley on personal defense situations. as for my skills, JNewell, I'll take luck any day i jerked the trigger high and right so instead of the heart, the round went through his spine. but i digress....i can say i still practice the double tap at 7-10 yards. i'm sure when all else fails "empty the magazine" would seem like a prudent course of action.
