My original question was best answered by Ram Rod, so go re-read his post and ask yourself if you are training properly for a close in surprise kinda gun fight. I train to empty my gun into BG in about 1 to 2 seconds (I've never timed it). Shoot fast for COM, focus on front sight and multiple hits to stop the threat before he can shoot me. The as many as it takes answer is good, but as someone else said shooting a BG 17 times may get you convicted of a crime. I honestly don't know how a BG will react to 4 158 grain hydra shocks in rapid succesion, but I don't think he'll have much fight in him. i think if I carried a higher capacity gun I would train to fire 5 round groups then assess the target. your thoughts are welcome.
