Training? Experience?If you cannot hit your target with 10 rounds, why should you take that weapon into a theater, school, church or shopping center and claim it is for defense? those ten bullets are going somewhere, if not at your target. And those ten bullets are lethal when fired among innocent bystanders.
Yours is just another badly formed rationalization to defend a Rambo fantasy.
So why does virtually every law enforcement agency issue pistols with high capacity magazines?
I just assumed they had more than one bullet in their gun cause there might be more than one bad guy and the bad guys might be shooting back at them. That and dead men tell no tales. After the cops blow up the babies in their cribs with grenades they can follow up a melee of rounds to kill all the witnesses. JK to all my cop friends who are not out to blow up babies.
