I am so sick of these penetration threads. Are you lining people up and executing them, Nazi style? Are you shooting through walls and doors in your defensive scenario? Are you a cop? Do you really want to be a cop?
I am in Law Enforcement, are you a psychic? .45 ACP, is a lousy round, any way you slice it. Slow, bulbous, has a terrible arc trajectory and has abysmal penetration. Out of the big 3, I'd take them in this order and this grain weight, .40 S&W (135gr - 155gr), 9mm Luger (115gr - 127gr), .45 ACP (165gr - 200gr). Anything else in those three calibers is garbage.
