FN 509 Compact MRD Comp 9mm Optics Ready Pistol - FDE - 66-101795

Engineered for precision and control, the FN 509 Compact MRD Comp 9mm Optics Ready Pistol in Flat Dark Earth delivers full-size performance in a concealable package. This striker-fired semi-automatic handgun combines FN’s proven 509 platform with an integrated compensator and low-profile optics mounting system, making it an ideal choice for tactical shooters, competitive competitors, and those seeking reliable defensive carry options.

Key Features and Benefits

• Integrated Compensator: The quick-detach compensator reduces muzzle rise and felt recoil, enabling faster follow-up shots and improved accuracy during rapid fire.
• Optics-Ready Design: Patented FN Low-Profile Optics Mounting System accepts a wide range of miniature red dot sights with direct mount plates, while co-witnessing blackout iron sights provide backup reliability.
• Compact Yet Capable: At just 4.02 inches barrel length and 7.4 inches overall, this model balances concealability with the capacity of higher-volume magazines (10, 12, or 15 rounds).
• Enhanced Ergonomics: Ambidextrous controls, improved texturing on interchangeable backstraps, and a flatter-faced trigger promote intuitive handling and precise trigger control for users of all hand sizes.
• Durable FDE Finish: The Flat Dark Earth polymer frame and slide coating offer corrosion resistance and tactical aesthetics suited for demanding environments.
