I will open up the can worms. 9mm is smaller, but faster than 45 ACP.
The difference in shooting is the 45 has a bit more recoil over a bit more time than the 9mm and of course it makes a 45 caliber hole in the target instead of a 355 caliber hole.
Personally I see it as a coke vs pepsi thing and some folks like one brand instead of the other. I am more along the lines that each are fine and I shoot whatever is the cheapest.
