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 Performance Center Ported model has a ported barrel and slide to reduce muzzle flip. The trigger stop is adjustable to prevent overtravel. The trigger has been enhanced and the sear has been upgraded to Performance Center standards. Three newly-enhanced interchangeable textured palmswell grip sizes come with the pistol for better control and fit. In addition, the PC Ported is part of Smith & Wesson's C.O.R.E. system. The pistol includes an optics mounting kit with the slide cut to accept the following optics: Trijicon RMR, Leupold Delta Point, Jpoint, Doctor, C-More STS, and Insight MRDS.
