The .500 S&W Magnum or 12.7×41mmSR is a .50 caliber semi-rimmed revolver cartridge developed by Cor-Bon in partnership with the Smith & Wesson "X-Gun" engineering team for use in the Smith & Wesson Model 500 X-frame revolver and introduced in February 2003 at the SHOT Show. It was intended to be the most powerful handgun cartridge to date, with the capacity to harvest all North American game species. More powerful handgun cartridges, such as the .500 Bushwhacker, have emerged since, however.
