I got my 460 Smith and Wesson Magnum X-frame back from the Performance Center. I have the 5 inch muzzle-brake model. The Performance Center put a different rear sight with a higher blade on it. It shoots 45 Colt accurately and 454 Casull accurately also. I used a shooting bench to steady my gun and rung the metal all up and down the line. I am going to shoot paper soon. I will report back after that.
