The FN 509 LS Edge is the result of FN America’s design for the US Army’s XM17, the Modular Handgun System. With more than 100 years of firearms excellence and a supplier of U.S. Army M4 rifles, FN America brings expertise in ruggedly reliable and modular design to the civilian market, as evidenced by the 1 million rounds FN reports to have expended in testing this handgun. This next generation semi-automatic 9mm pistol presents a strong entry into a competitive field, fully capable of home defense, self-defense, target shooting, competition, and whatever else you may require from it.

The LS Edge model has been redesigned specifically for competition use with a 5" barrel with a skeletonized slide to reduce weight, suppressor height sights with a fiber optic fron sight, and a slide that is milled for use with red dot adapter plates. Additionally, it comes with a flared magazine well, an enlarged magazine release, and three 17 round magazines with aluminum baseplates allowing them to drop faster for faster magazine changes. It still retains all the fully ambidextrous functionality and ergonomics that made the original so popular.

The FN 509 features ambidextrous controls with left and right-side magazine releases and slide locks. Capable of full operation in either hand, the FN 509 is perfect for left handed shooters or for personal protection where switching hands can be critical.

FN has a strong history of producing fine barrels and the FN 509 is no exception. The 5” cold hammer forged barrel includes a recessed target crown, which protects the lands and grooves in one of the most vulnerable areas that is vital for maintaining consistent accuracy and bullet stabilization. The flat faced trigger breaks cleanly after a smooth take-up, with a short, positive, and audible reset. There is no grit, no excessive slop, or sponginess present here. The low bore axis of the design keeps felt recoil low and muzzle flip to a minimum. With the improved ergonomics, the clean trigger, and the very manageable recoil, the shooting experience is smooth and controllable.

FN America’s FN 509 is a strong evolution of the striker-fired polymer frame pistol, representing fantastic reliability in a truly ambidextrous and ergonomic package for a price that is hard to beat.
