FN 509C MRD 9mm Optics Ready Pistol 15+1 3.7" Barrel Black

The FN 509C MRD delivers optics-ready versatility in a compact striker-fired platform engineered for serious applications. This pistol combines FN's military heritage with modern features that address the evolving needs of law enforcement, competitive shooters, and concealed carry practitioners.

What Makes This Different

Unlike standard compact pistols, the 509C MRD features a factory-milled slide with FN's Low-Profile Optics Mounting System that accepts popular red dot sights without adapter plates. The recessed target crown barrel design enhances accuracy while the ambidextrous controls accommodate both left and right-handed shooters. FN's Cold Hammer Forged barrel process creates a bore that maintains precision through extended firing schedules.
