The Smith & Wesson Model 351 C is an ultra-lightweight, compact "Centennial" style revolver chambered in the punchy .22 Magnum (.22 WMR) cartridge [1]. Built on S&W's famous aluminum-alloy J-frame, it features a completely internal hammer [1]. This makes it a popular choice for deep concealment or a pocket backup gun, as there is no exposed hammer to snag on clothing during a draw.
