I know that all the purists believe that 1911's should be 45's, but I can tell you with no doubt that the Pro Series 1911 9mm is an exceptional weapon. I am far from being anywhere near a "great" shot with a handgun, but this gun makes me look good. It feels good (a little heavy) fits my hand well and hits exactly where you point it. Great gun! Ok, I'm off the soap box.
