The Smith & Wesson M&P C.O.R.E Pro series takes the M&P 9mm up to competition level with a variety of upgrades and improvement. The most notable upgrades are on the black armornite coated slide, the raised suppressor height style sights allow you to co-witness a micro red dot like a Trijicon RMR or Vortex Viper that can be mounted once you remove the top plate covering the milled out section for just that purpose. The M&P C.O.R.E Pro series delivers impressive accuracy and balance with its 5" barrel which is perfect for competition shooting. Interchangeable palm swell grips are heavily textured to keep the gun firmly in your hand under any conditions and with 3 sizes to choose from, you can get the best possible fit for your hand. What is not immediately noticeable on the Pro series M&P 9mm semi auto is the tuned trigger, which breaks cleaner than the standard pistols for even greater accuracy on target. The Smith & Wesson M&P9 Pro Series C.O.R.E comes with 2-17rd magazines.
