The Smith & Wesson M&P 5.7 will light up the range and quicken your pulse. With its rotating 5” Tempo Barrel System, the new M&P 5.7 pistol utilizes the ballistics of the 5.7 x 28 round to produce a great self-defense pistol that can easily put multiple rounds down range with light recoil. With a 22+1 max capacity and two 22-round mags, you'll never need to worry about running out of ammo. Features of the S&W M&P 5.7 include precise front serrations, lightning cuts, and a 5" barrel with 1/2x28 thread for mounting a muzzle device or suppressor. The TEMPO barrel system features an internal rotary barrel and external shroud allowing for muzzle device mounting. The proprietary gas system ensures the projectile has exited the barrel before the cam opens and ejects the casing. This allows for the smooth cycling of rounds and reduces the risk of malfunction. This M&P57 is the one without a manual safety.
