Marshall Sanow stats on actual gun fights. I know the big bullet freaks refuse to believe they're not biased, but the .45 ball ammo has about a 60% "stopping power" rating which is about even with some .32 hollowpoint, though I think even though I do believe the M/S stats to be founded on good statistics, I'd rather be shooting .45 ball than any .32 anything, LOL!
I'd rather be shooting 9mm +P+ hollowpoint than either one of 'em, though.
Hey, but whatever works for you! Forget hollowpoint for military use, though. 9mm ball is somewhere south of 60% in M/S stats, don't remember exactly where, but it's less effective. Neither one is great, though. That's why I was wondering why they'd have to adopt a round ball? Seems like a truncated cone bullet would work a bit better, maybe even up another 6 or 8 points in actual gunfights. I know I have decent results from .357 magnum SWCs. They penetrate, yet leave a good diameter of destroyed lung tissue reliably in deer. A round nose would zip through like a field point arrow by comparison. SWCs and truncated cone shapes do more tissue damage and I don't see why, so long as they're FMJ, they would be "illegal" by the Geneva convention. Maybe it reads that it HAS to be round, don't know.
At any rate, pistols are not front line combat weapons for obvious reasons. Their "stopping power" is really a moot thing in military service. They're not meant to be used in actual battle, horse cavalry having been made obsolete a few years back.
