The Smith & Wesson M&P 40 is a popular double-action-only, semi-automatic pistol chambered in .40 S&W, with a 15+1 round capacity in the full-size model and 10+1 capacity in the compact version. Known for its polymer frame and Browning locking system, the M&P 40 is widely regarded for its reliability and customizability. It offers ambidextrous features, such as a reversible magazine release, making it easier for left- or right-handed shooters to operate. The pistol also comes with optional Tritium night sights, enhancing its utility in low-light situations. Its angled wave-design grip and larger controls are designed for ease of use, particularly benefiting shooters with larger hands. The M&P 40 M2.0 is an upgraded version of the original M&P 40, offering improvements across several key areas. It features an extended stainless-steel chassis that reduces frame flex and enhances durability. A low bore axis reduces muzzle rise for quicker target re-acquisition, while the crisper, lighter trigger with tactile and audible reset improves shooting performance. The M2.0 is equipped with an aggressively-textured grip and comes with four interchangeable palmswell inserts (S, M, ML, L) to fit a wide range of hand sizes. Available in matte black or FDE finishes, the M&P 40 M2.0 maintains its reputation as a reliable choice for personal defense, professional use, and sport shooting.
