Beretta KILLS the INOX versions by using the black controls. I hate the two tone look.
I've owned a all stainless INOX 92, a Centurion, a 92FS, and now am left with a regular M9 and a Brunition 92FS Vertec. Gotta admit, the grip on the Vertec beats the 92FS, and I'm a big guy with big hands.
I agree with Pilot I think the contrast of the black controls look better than if they were all the same color. Also I don't think Beretta ever made an all stainless gun.
