FN 509 MRD FDE Features
This model includes FN’s patented Low-Profile Optics-Mounting System, allowing direct attachment of the Holosun 407C red dot sight with a co-witness to the blacked-out iron sights. The pistol features a flat-faced precision trigger with a clean 6.6-pound pull and a crisp break for enhanced control during rapid fire. The enhanced grip texture and interchangeable backstraps deliver superior handling and customizable ergonomics in any environment.
Built to FN’s rigorous quality standards, the 509 MRD features a recessed target crown on its stainless steel barrel to protect muzzle integrity and ensure consistent accuracy. The polished chamber and feed ramp improve cycling reliability across a wide range of 9mm ammunition types. Additional features such as a MIL-STD-1913 rail, non-manual safety design, and fully ambidextrous controls make this optic-equipped FN pistol mission-ready right out of the box.
