The M&P 5.7 uses S&W's TEMPO gas-operated locked-breech two-part barrel system and an internal hammer-fired action. The 5.0 in stainless-steel barrel is Armornite treated and threaded 1/2x28; a multi-port compensator is installed, and both the factory thread protector and an A2-style flash hider are included.
The slide is stainless steel with an Armornite finish and features forward and rear serrations, top lightening cuts, and an optic cut. The frame is black polymer with an integral Picatinny-style accessory rail.
This pistol arrives optics-ready and already equipped with the Viridian RFX15 micro reflex sight featuring a green 3 MOA dot. Steel 3-dot sights (white-dot front, two-dot rear) remain in place for a clear backup sighting option.
Controls include ambidextrous slide stop levers and a reversible magazine release. The flat-faced trigger has a safety tab, and this No Thumb Safety configuration omits an external manual safety while retaining a trigger safety.
Capacity is 22+1, and three 22-round stainless-steel double-stack magazines are included. Overall length is 8.5 in, height 5.25 in, width 1.10 in, and weight 26.7 oz. Made in the USA.
