Smith and Wesson has shown support for the 5.7x28mm cartridge with their new M&P 5.7 pistol.

Smith and Wesson states “New for 2023, chambered in the high-velocity, flat-shooting center-fire 5.7x28mm, the M&P®5.7.

Featuring our new TEMPO® barrel system, a lock-breech two-part barrel with a proprietary gas system, the M&P®5.7 is reliable in extracting and cycling the 5.7x28mm round.”


  • M&P®5.7 features front serrations, lightening cuts, and 5″ barrel with 1/2×28 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 cycling.
  • M&P®5.7 is fully ambidextrous with mirrored controls and reversible mag release. The frame features a full-size grip with enhanced texturing.
  • The slide on the M&P®5.7 features three-dot white sights as well as an optics-cut and is available with or without a thumb safety.
  • The internal hammer-fired single-action with flat-faced trigger is light and crisp with an audible reset.
