I'm new here so if I'm not doing something right, help me out! lol I currently have a Beretta Px4 storm in 40S&W and I love it. I was just wondering if anybody has seen a website where you can buy custom barrels for it. I would like to have a 4.6" barrel like what comes with the SD version of the Px4 .45. But I would like it to be chrome, and threaded if possible. Any help would be appreciated. Thanks!
