FN America

The FN 509 Tactical is a striker-fired 9x19mm pistol developed from FN's submission for the U.S. Army's Modular Handgun System competition, featuring a threaded barrel for suppressor use, suppressor-height night sights, and an optics-ready slide with FN's Low-Profile Optics Mounting System. It retains the full ambidextrous controls, cold hammer-forged barrel, and enhanced grip texture of the standard 509 while adding features for tactical and duty applications. The 509 Tactical's 24-round extended magazine and suppressor-ready configuration make it one of the most capable out-of-the-box tactical handguns available. It has been widely adopted by law enforcement tactical teams and is marketed as a duty-ready pistol requiring no aftermarket modifications.

The FN 502 Tactical is a .22 Long Rifle pistol designed as a trainer for the FN 509 series. It features the same ergonomics, controls, and size as its centerfire counterpart. The slide is constructed from aluminum for reduced weight. The pistol comes optics-ready with a threaded barrel for suppressors. It is one of the few .22 pistols designed to mirror a duty-size handgun.
