The M&P M2.0 Full Size in .40 S&W pairs a 4.25-inch stainless-steel barrel with an Armornite finish and a matching Armornite-treated stainless slide. This striker-fired model uses a hinged, pivoting trigger with a tactile reset and integrated trigger safety, and it is configured from the factory with no thumb safety.
Its polymer frame features the extended embedded stainless-steel chassis for stability and durability, along with the aggressive M2.0 grip texture. Four interchangeable palmswell inserts (S, M, ML, L) allow quick customization of grip size and feel.
Controls are practical and ambidextrous where it matters, including slide stop levers on both sides. The integral 4-slot accessory rail supports common weapon-mounted lights or accessories. Capacity is 15+1 with the included factory steel double-stack magazines.
Steel 3-dot sights are dovetailed front and rear, and the slide carries front and rear serrations with a scalloped/wave pattern for confident manipulation. Markings include "M&P 40" and "M2.0," plus the factory caution "Capable of firing with magazine removed." Made in the USA with a black finish throughout.
