FN 509 Compact MRD 9mm Blue/Black Pistol

The FN 509 Compact MRD is a compact 9mm pistol designed for concealed carry and adaptable defensive use. Its striker-fired double-action system combines a consistent trigger pull with an integrated trigger safety, while the polymer frame provides a durable, lightweight foundation. The 3.7-inch recessed target-crown barrel pairs with a serrated black PVD steel slide for practical handling and long-term wear resistance. An optics-ready MRD interface supports compatible red-dot sights, and factory night sights provide a visible aiming reference in changing light. The pistol includes FN 509-pattern magazines and an integral Picatinny rail for compatible accessories.
