The Smith & Wesson M&P 9 is a striker-fired semi-automatic pistol chambered in 9mm with a magazine capacity of 17+1 rounds. Initially launched in 2005, the pistol was not immediately as popular but gained traction with the release of the M&P 2.0 in 2017. This update brought significant improvements, including an upgraded polymer frame, enhanced magazine release, and a re-engineered trigger. The 2.0 also features aggressive grip texturing, improving handling and control. The M&P 9 line includes multiple barrel lengths, such as the full-size 4.25", 4" compact, 3.6" sub-compact, and 5" Performance Center Competitor models, catering to various user preferences. The M&P line also extends beyond 9mm, offering options in .40 S&W and .45 ACP. The M&P 9 features a stainless steel barrel and slide with a matte black polymer frame, providing durability and a sleek look. It incorporates a low bore axis, which reduces muzzle rise and allows for faster aim recovery. The M&P 9 M2.0 model, an upgraded version, offers a crisper trigger with tactile and audible reset, and four interchangeable palmswell grips for a customizable fit. Designed for personal defense, professional, and sporting use, the M&P 2.0 also features Armornite finish for enhanced corrosion resistance and durability.
