The Performance Center M&P9 L (Long Slide) is a 5-inch barrel variant of the M&P9 tuned by the S&W Performance Center for competition use. The extended barrel adds sight radius and velocity over the standard 4.25-inch M2.0. Performance Center features include a PC-tuned trigger with lighter pull and shorter reset, ported barrel and slide to reduce muzzle rise, fiber optic sights front and rear, and an enhanced chassis. It is the factory competition answer to shooters who would otherwise send a standard M&P9 to Apex for a trigger job. Type: Pistol Action: Semi-Automatic Caliber: 9mm Capacity: 17 Year introduced: 2015, USA Weight: 26.5 oz Overall length: 8.5" Status: Active Intended use: competition, duty
