The sad thing about the entire subject is after just getting the laws of physics confirmed, I like the principle of the modern semi auto. I'm not sure we've improved much, if at all, over the 45 acp, but we have come up with similar rounds with more available shots.
I don't believe in wonder guns. I don't even believe Life is Fair. I've heard horrible tales of multiple hits from the 44 mag failing because the hollow points filled with material on the way in, did not expand, did not hit a vital CNS area on the way out, and the attacker continued.
There are people who've walked into ER's with axes and crowbars stuck into their brains- and lived.
If I wasn't living in the place most of you have to pay money to visit, if I wasn't outdoors a lot, if I lived in the city and worried about over penetration, I would use the semi auto more often than the revolver. Ironically, because I can keep a 1911 ready in my house of small children, (they can't rack the slide) I actually use it at least as much as a revolver today.
But the revolver is a wonder- it can go down to semi auto power, up to hunt or for vehicular defense, and of course, target.
