I will happily concede that all things being equal, 45acp is a better round than the 9millie. However, a quality 9mm hollow point can narrow the performance edge. For me since 45acp runs 50%+ more per box of 50, I can practice far more with 9mm and increase overall proficiency. So when the bullets fly, so to speak, I like to think I'm FAR more likely to be on target with a 9mm. What say you?
