Fn 509M Tactical 9mm Luger 4.5 inch 15+1 Flat Dark Earth

The FN 509 Tactical continues FN's line born from the Modular Handgun Trials and brings a duty-ready package for concealed-carry, home defense, and range work, with a Holosun red dot pre-installed for fast target acquisition and an optic-cut/serrated slide that accepts plate-mounted sights; its 4.5-inch cold hammer-forged stainless steel barrel is threaded 1/2" x 28 to accept most 9mm suppressors and uses a thread cap with O-ring to keep the cap secure during use, while suppressor-height three-dot night sights maintain sight picture when a can is mounted. Chambered in 9mm Luger with a striker-fired action and a 15+1 capacity, the 509T pairs a Flat Dark Earth frame with interchangeable FDE backstraps for a consistent grip feel and ergonomics across hand sizes; the slide cap protects iron sights when running the red dot and provides a textured racking ramp useful when manipulating the slide against clothing or a boot. With near-slide-length 24-round magazines available to maximize on-gun capacity without adding bulk, the pistol requires an FFL transfer and suits shooters looking for a robust, optics-ready tactical handgun from FN's trusted 509 series.
