Built as a successor to FN's proven FNS series of striker-fired pistols, the 509 is FN's premier modern striker-fired duty and defensive pistol. The Edge series of the 509 model is a high-performance tactical pistol meant to tackle the most demanding of environments. The pistol features an optics-ready, long slide design with lightning cuts along with a flat-faced trigger to maximize handling, shooting performance, and modularity. A tough, aluminum flared magwell allows for speedy reloads even under pressure. This model features a two-tone finish with a black frame and a gray slide. Three 17-round magazines are included.
