The Smith and Wesson M&P 5.7 builds on the proven track record of the M&P platform and introduces new improvements like the Tempo Barrel System to improve the shooting experience substantially. This 5.7x28mm pistol has an optic-ready slide, with an ambidextrous slide release and front and rear serrations for improved manipulation. The rotating, threaded 5-inch Tempo barrel utilizes the ballistic properties of the 5.7x28 cartridge to facilitate fast, repeatable, and accurate shots. The gas operated, locked breech Tempo system does not allow the barrel to cam until the bullet has passed the gas port. This pistol features a reversible magazine release, two 22-round magazines, a slim textured grip, and a crisp single action trigger break.Features: Semi-automatic 5.7x28mm pistol Full-size black polymer frame with grip texture Threaded barrel with thread protector Optic-ready slide White dot sights 22-round capacity Ambidextrous slide release Reversible magazine release No thumb safety
