One through the floor brings anyone advancing towards you into slow motion. That big question flashes across their mind, “Is this worth dying for?”
Two through the chest stops 'em cold...I don't want them advancing towards me even in slow motion. Ever see that study on how quickly an attacker with a knife can close a 21ft distance? Remember that a dying man can still harm you...a dead one cannot.
