FN 509 Tactical 9mm Blue/Black Pistol

The FN 509 Tactical is a duty-oriented semi-automatic pistol developed from FN's U.S. Army Modular Handgun Trials submission and refined through the FN 509 program. Its 4.5-inch threaded stainless steel barrel features a target crown and thread cap, while suppressor-height night sights provide a clear aiming reference. The FN Low-Profile Optics Mounting System accepts miniature red dot optics and is designed to co-witness with the iron sights. Raised slide wings help protect sight alignment, and the textured slide cap offers an alternative surface for manipulating the slide. The polymer frame includes interchangeable backstraps for a more tailored grip fit.
