I dunno Lloyd.....I think as the bullets get better, the 9mm does as well. My way of thinking is that you can't go wrong with a 9, 40 or 45. I do think the 40 is a compromise caliber...that's my opinion...and there's not a thing wrong with it...that's also my opinion. I'm much more concerned with velocity from short barrels than I am with caliber these days. I DO think the 45acp is still the king, but don't feel at all undergunned with the 9mm in a +p or +p+. I should do a "hog" test one of these days when I'm out hunt'n.
BTW...I keep up with all of this on "Stopping Power.net" which is Evan Marshall's site.
