Whenever I advocate for the 9mm, people accuse me of sitting down when I go to the bathroom...
But IMHO, dead is dead, and both calibers will kill you.
Agreed. Lethality has a lot more to do with placement than size of the hole. That said, I prefer .45 because I like my 1911 better than my Glock 9mm. The 9mm is considerably cheaper to shoot.
