That about sums up what I've come to think about the debate between various service calibers in pistols. I mean, maybe .40 and .45 are marginally better than 9mm but really, it's not gonna make that big of a differene. If you ever encounter a situation where several center mass hits with quality 9mm ammo can't take care of it, you need to either 1) consider retreating or 2.) get to a long gun if that isn't an option. If you really think about it, if it's not dying after beiing hit with a 9mm, that little bit of extra power a .40 or .45 offers probably won't make a difference. What do you guys think?
