I am not much of a pistol shooter. But what I do know is I don't like the Glocks. And most of the guys I work with have them. I think because we are affiliated with the prison we get the blue label deal. Actually I am a revolver type of guy. But I have a Ruger 911 45 that I love to shoot. And my old 357 686 S&W I can hang with them. I just never liked Glocks and have seriously considered the SIG. Is it the P320 that you can interchange barrels? I think I would like one
