The FN 509 LS Edge pistol in 9mm with a 5-inch long slide and black/gray finish (brand part no. 66-100940) is the most advanced striker-fired 509 handgun FN builds, developed for environments where split-second control matters. FN America equips the LS Edge with a crisp, flat-faced trigger that breaks cleanly at 90 degrees, a flared aluminum magazine well, and lightening cuts on the long slide that reduce weight and improve balance for faster follow-up shots. The pistol integrates FN’s Low-Profile Optics-Mounting System compatible with most common red dots, and a target-crowned, hammer-forged barrel delivers tack-driving accuracy. Two interchangeable backstraps fit a range of hand sizes, and the pistol ships with a ballistic case, four MRD mounting plates, and three magazines. Among long-slide semi-auto handguns, this 509 LS Edge configuration favors shooters who want tactical control and competition-grade accuracy in one platform.
