9mm more accurate? Gimme a break. They are both as accurate as the shooter.
The .45 does have the priviledge of being used for serious target shooting, so some may say the .45 is more accurate, but no one can even begin to claim it is less accurate.
So, if the 9mm is just as good as the rest, then what is the point of anything more powerful? What's the point of the .357 Magnum? What's the point of the .357 Sig? What's the point of the .40 cal or the 10mm?
It seems to me that there must be SOME advantage to a more powerful round and a larger caliber, or else we might as well all carry the 9mm. The 9mm holds more ammo, kicks less, and is cheap. But, the thing is, I really think there must be SOME advantage to shooting a bigger bullet and/or a more powerful cartidge, otherwise the .38 Special would work just as well as the .357 Magnum. Which of the choices would you rather be shot with, in the exact same location?
