FN 509 Tactical 9mm 4.5" Threaded Barrel Optics Ready
FN 509 Tactical 9mm with 4.5" threaded barrel, optics-ready slide, suppressor-height night sights, and low-profile mounting system. Includes two 10-round magazines and soft case.
FN 509 Tactical: Modern Tactical Design Meets Proven Performance
The FN 509 Tactical represents a significant evolution in tactical pistol design, drawing from FN's extensive testing during the U.S. Army's Modular Handgun Trials while incorporating the proven improvements of the FN 509 platform.
Optics Integration
This pistol features FN's patented Low-Profile Optics Mounting System, which accommodates more than ten commercially available miniature red dot optics. The system allows your chosen optic to co-witness with suppressor-height night sights, maintaining sight picture redundancy. The design requires no direct slide milling, ensuring compatibility with future optics developments.
Slide and Sights
The matte black stainless steel slide features serrated edges for enhanced grip during manipulation. The slide cap includes raised sight wings that protect iron sight alignment during drops or rough handling. A textured ramp enables reliable slide racking against a belt loop, pant pocket, or boot—essential for one-handed operation in demanding situations.
Barrel and Suppressor Compatibility
The 4.5-inch cold hammer-forged stainless steel barrel features a target crown and ½" x 28 threads, accepting the vast majority of 9mm suppressors on the market. The included thread cap features an integrated O-ring to prevent loosening during use.
