FN 509 LS Edge 9mm 5" Graphite 10+1 66-100940

FN 509 LS Edge

The FN 509 LS Edge is a full-size, long-slide 9mm pistol built for demanding tactical and competitive environments where speed and control are critical. It features a 5 inch target-crowned hammer-forged barrel, lightening-cut long slide, and FN's patented Low-Profile Optics Mounting System for direct mounting of most major miniature red dots. Finished in long-wearing graphite PVD with a polymer frame, this striker-fired pistol delivers a 10+1 capacity and ships with three magazines for ready use.

A crisp flat-face trigger breaks cleanly at 90 degrees with a 4.5 to 6.7 pound pull, while the conical striker design reduces overall trigger weight. Precision fiber optic front and blackout rear sights co-witness with mounted optics, and the flared aluminum magazine well combined with oversized ambidextrous controls and knurled magazine release support rapid reloads under stress. Enhanced perimeter frame texture, interchangeable backstraps, and a MIL-STD-1913 rail complete the ergonomic package for improved grip and accessory mounting.

This pistol is well suited for competition, defensive training, and duty applications that demand immediate recovery, precise tracking, and optics readiness. The combination of a long slide for extended sight radius, factory performance enhancements, and proven FN reliability makes the 509 LS Edge a high-performance choice for shooters who need every advantage in control and marksmanship.
