FN 509 MRD Flat Dark Earth 9mm 4.5″ Barrel 10-Rounds

FN 509 MRD Features

The 509 MRD features an optics-cut slide with a proprietary mounting system that accommodates most leading red dot sights. The suppressor-height co-witness iron sights allow seamless transition between red dot and backup sights, enhancing accuracy and target acquisition in any lighting condition. The hammer-forged stainless steel barrel is precision-made and finished with a recessed target crown for added accuracy and protection.

Its Flat Dark Earth PVD slide finish and matching FDE polymer frame give it a distinctive tactical look while providing excellent corrosion resistance. The full-size frame includes an integrated Picatinny rail for lights or lasers and is paired with interchangeable backstraps for personalized ergonomics. With a trigger pull between 4.5 and 6 pounds, ambidextrous controls, and a 10+1 capacity, the FN 509 MRD is a high-performance choice for both right- and left-handed shooters.
