Nothing says, "Hit!" quite like a 0.452" hole in a target, paper or otherwise. And I own both a 9mm and a 45 Colt. A 255 grain bullet even at 800 ft/sec will never 'fail to penetrate' a target, in my experience anyway. I carried a 38 Spl because it was issued, and never felt undergunned, and when they issued the Sigarms P229 DAO in 40 S&W, I liked that one too, and preferred it to the 38. The 180 grain bullet at 950 ft/sec spoke quite nicely.
