I'll go that one further, with a 9mm, or smaller, always triple-tap and repeat until the bad guy stops moving.
I've seen a 350-pound druggie take 19 rounds of 9mm, including three shots to the head...
yet he was only dropped by two shotgun slugs while charging the officers poking him with 9mm rounds.
Sometimes its the round, sometimes its the target...its why I use a 10mm for concealed carry...
but to do so, I often have to plan out my wardrobe quite carefully, and use alternative carry methods (diaper bag-I've got twin boys).
(why do your babies have earmuffs on?? Just in case I need to shoot a bad guy
