I like the speed and penetration of a 9mm. The 1160 fps is better as far as speed goes and the round is a little smaller. Also I like 9mm because its cheaper to train with.

Please, not another 9mm vs. .45 thread.

As Overkill mentioned... If you want honest answers, peruse this site. If you want a lot of snarky answers, stick with yet another thread.

Caliber choice lies solely on the shooter. Fortunately, I can shoot a multitude of calibers comfortably; therefore, I keep five calibers laying around (still "need" more). My uncle shoots 9 mm almost exclusively, because he prefers 9 mm. Shoot what you like. As long as you load a good name brand defense ammo you don't have anything to worry about.
