Smith & Wesson Model 457

The Smith & Wesson Model 457 is a compact semi-automatic pistol from Smith & Wesson's Second Generation series of alloy and steel-framed handguns in company's Value Line of budget-priced auto pistols.[1][2] The 457 is a compact pistol chambered for the .45 ACP cartridge.[1] The design utilizes a double-action/single action trigger mechanism, meaning that the first shot is fired with long double-action pull, with following shots fired in single-action.[3] The 457's external hammer omits a thumb spur, thereby reducing the risk of being caught on clothing during unholstering.[3] A slide-mounted safety lever that drops the hammer from its cocked position when moved to the 'safe' position.[3] The 457 has a 95 mm (3.75 in) barrel and 7-round magazine capacity.[3] The Model 457 was produced with a matte-finish carbon steel slide and blackened aluminum alloy frame. Other versions include the Model 457S with a stainless steel slide and aluminum frame, and the Model 457TDA with a satin-finished aluminum frame and black carbon steel slide.[3][1]
