No other polymer pistol offers the M&P's combination of versatility, durability, and safety. A reinforced polymer chassis, superior ergonomics, ambidextrous controls, and proven safety features combine to make the M&P the new standard in reliability. The improved trigger weight and feel, and unique takedown method set the M&P apart from other modern lightweight pistols. The M&P is made out of Zytel polymer reinforced with a stainless steel chassis and treated with Smith & Wesson's proprietary Melonite nitriding process that produces a matte gray-colored, non-glare surface with a 68 Rockwell C surface hardness rating. Its very low slide profile holds the barrel axis close to the shooter's hand and makes the M&P more comfortable to shoot by reducing muzzle rise and allowing for faster aim recovery in rapid shooting sequence. Every M&P comes with three interchangeable palmswell grips. This model has a unique carbon fiber finish.
