The Smith & Wesson M&P 5.7 combines the flat-shooting 5.7x28mm FN cartridge with the innovative TEMPO rotating barrel system. Its internal hammer-fired, gas-operated locked-breech design keeps the barrel locked until the projectile passes the gas port, supporting consistent cycling and dependable performance. The five-inch threaded barrel and optic-ready slide provide a versatile foundation for range use, while the textured polymer grip, flat-face trigger, forward slide serrations, and Picatinny-style rail enhance control and adaptability. An ambidextrous manual thumb safety, reversible magazine release, and ambidextrous slide stop accommodate a wide range of users.
