The FN 509 Compact represents the next evolution in personal protection with the performance of a full-sized pistol in a concealable size. With low-profile, snag-free sights, it's the right addition for every day carry and the perfect fit for inside the waistband holsters. The pistol is 9mm and striker-fired with 3.7-inch barrel and the capability to accept all higher capacity FN 509 magazines. The improved controls aid in manipulation, the new improved texturing on the two included backstraps provides better recoil management, and a new flatter faced trigger enhances trigger control with a cleaner break.FeaturesStriker-fired autoloaderPolymer construction with replaceable steel frame/slide railsEnhanced grip texture which enables faster follow-up shots in all conditionsInterchangeable backstrapsMIL-STD-1913 accessory mounting railFully ambidextrous slide stop lever and magazine release
