FN 509 MRD 9mm Pistol 10+1 Capacity Flat Dark Earth PVD Finish

The FN 509 MRD delivers optics-ready performance in a striker-fired platform engineered for both duty and personal defense applications. This pistol features a Flat Dark Earth PVD coating that provides superior corrosion resistance while maintaining the tactical aesthetics professionals demand.

What Makes This Different

The MRD (Miniature Red Dot) configuration comes factory-machined with mounting plates for popular optic systems, eliminating the need for custom gunsmithing. The cold hammer-forged barrel delivers consistent accuracy while the enhanced grip texture provides secure handling in adverse conditions. FN's proprietary trigger system offers a crisp break with tactile reset, surpassing many factory striker-fired triggers in both feel and consistency.

Range testing demonstrates consistent sub-3-inch groups at 25 yards with quality ammunition. The pistol cycles reliably with both standard pressure and +P loads, making it suitable for law enforcement duty use. Weather sealing at critical points maintains function in rain and dust conditions. Competition shooters appreciate the flat trigger face and consistent pull weight across temperature ranges.
