The Model 500 on the X-frame was introduced in 2003 as the most powerful production revolver in the world, a title it has retained. The 6.5-inch barrel is the most common standard configuration, balancing portability with velocity. The five-shot X-frame was purpose-engineered for the .500 S&W Magnum cartridge, as no existing frame could contain the pressure. Designed for large and dangerous game hunting at close range. Type: Revolver Action: Double-Action Caliber: .500 S&W Magnum Capacity: 5 Year introduced: 2003, USA Weight: 72.5 oz Overall length: 13.5" Status: Active Intended use: Hunting, Field
