The original M&P9 first generation introduced in 2005 was the pistol that revitalized Smith and Wesson in the duty-pistol market after years of declining law enforcement adoption. The polymer frame, replaceable backstraps, and striker-fired action positioned it directly against the Glock 17. A smoother trigger and more ergonomic grip distinguished it from the Glock in user testing. Discontinued in favor of the M2.0. Type: Pistol Action: Semi-Automatic Caliber: 9mm Capacity: 17 Year introduced: 2005, USA Weight: 24 oz Overall length: 7.6" Status: Discontinued Intended use: Service, Law Enforcement
