Fn 509 Mrd 9mm Luger 4.5 inch 17+1 capacity Flat Dark Earth

The FN 509 MRD in Flat Dark Earth blends duty-grade reliability with modern features for range days, competition, and defensive carry, offering a 9mm Luger, double-action striker-fired platform with a 17+1 capacity and a 4.5" barrel that balances sight radius and controllability; the MRD-series optic-cut, serrated slide accepts micro red dots for faster target acquisition while the 1:10" RH twist and 6.3" sight radius deliver consistent accuracy out of the box. At 27 oz. and 7.9" overall length, this semi-auto pistol feels substantial for recoil management yet remains ergonomic for extended shooting sessions, aided by FDE polymer grips and a Flat Dark Earth PVD frame finish that resists wear on duty or in the field. Trigger pull ranges from roughly 4.5 to 6.0 lb., providing a predictable, consistent break for training and high-stress use, and the 5.56" height and 1.35" width make holster selection straightforward. As an FFL-required firearm from FN's proven 509 MRD line, this optic-ready semi-auto is well-suited for law enforcement, competitive shooters, and experienced handgun owners seeking a robust, service-caliber pistol with tactical features and carry-friendly dimensions.
