I have both a 45 acp and a 9 mm glock.
I love my 45 acp no doubt about that. However, i think that people underestimate the effectiness of the 9 mm round. To me firing both all the time, my 45 makes bigger holes no doubt about that, however my 9 mm rounds move so fast and will go so far inside a bg I don' feel bad about either handgun. i often test both by taping two huge phone books together and hitting them with both rounds. Both rounds go all the way through the phone books and do some awesome damage coming out the back. However, i guess it depends on the ammo as well. However, i think my 9 mm will outpenatrate my 45 in most cases using ball ammo. Due it's higher speeds and size of the bullet. I know in WWII the 9 mm would most often penatrate are soldiers helmets and the 45 would also bouce off. I guess the point i'm making is don't underestimate the 9 mm round. It's deadly in most cases and I know a forest ranger in Alaska who killed a large Kodiak brown bear with a 9 mm round, of course he shot the bear in it's open mouth and the round went right through the bear's brain killing it instantly. I'm not saying that the 9 mm round is for bear hunting, of course it's not. However, the 9mm can kill with the best of them.
