MDG1976 said: The slide is slimmer than a Glock, the edges are bevelled (not square like a Glock or XD). The gun is very sleek and will be a good CCW. Beretta did a good job at eliminating uncessesary metal.
The PX4 certainly has great aesthetics, as far as plastic pistols go, but I just looked up Beretta's published dimensions on the PX4 and it confirmed my suspicions. It looks like the Glock 17 is smaller in all dimensions than the Beretta PX4 and weighs 5 ounces less.
