I recall Baby Face Nelson took 17 rounds before he expired, and took 2 agents out with him. Amazing what a determined adversary can do. One night a soldier put a round in his head (temple) with his service 9mm outside our tent and night shift. Of course it begs the question why, but odd things happen in war. However, it did not kill him. He was evacuated, and the poor soul never even lost conciousness. So hardball ammo does have a shortcoming.

But I can't carry a howitzer on my belt, or always hope for a spine or center brain shot. I think the 1911 is the most reliable piece overall.
