For durability, the M&P features a Zytel polymer frame reinforced with a rigid stainless steel chassis and a through-hardened Black Melonite stainless steel barrel and slide, giving the pistol a surface hard enough to sharpen a steel blade. Along with a new-age trigger system featuring a smooth 6.4 lb trigger pull and an advanced ergonomic design that features an 18-degree grip angle for natural aiming, the M&P has a combination of features that provides reduced felt recoil resulting in unparalleled shootability. The M&P pistol incorporates a number of unique features: three easily interchangable palmswell grip sizes for various hand sizes, an ambidextrous slide slope, reversible magazine catch and an enlarged trigger guard to accommodate gloved hands. With a Picatinny-style equipment rail incorporated for tactical lights and lasers, dovetail mount front sights, steel Novak Lo-mount carry rear sights (or Tritium sights), the M&P has it all, yet weighs only 24.25 ounces.
