In the world of modern firearms, the FN 509 MRD Fullsize Pistol stands as a testament to precision engineering and purposeful design. Crafted by Fabrique Nationale Herstal, this pistol is an ideal choice for those seeking a reliable full-sized duty-style firearm for personal or home defense.
The FN 509 MRD is chambered in the versatile 9mm caliber, offering both stopping power and manageable recoil. It features a robust 4.5-inch cold hammer-forged barrel constructed from proprietary machine gun-grade stainless steel. This ensures exceptional durability and performance under sustained use. The inclusion of a recessed target crown further protects rifling integrity, maintaining accuracy over time—a signature feature that sets it apart.
What truly distinguishes this model is its patented Low-Profile Optics-Mounting System, allowing for seamless integration with various optics without compromising on concealability or balance. This system caters to modern shooters' preferences for enhanced sight options while retaining traditional iron sights if desired.
The full-sized slide and frame are meticulously crafted to provide a secure grip with reduced felt recoil—benefits derived from the added weight and length inherent in its design. With an FDE (Flat Dark Earth) finish complementing its tactical aesthetic, this striker-fired pistol operates without manual safety mechanisms—streamlining readiness when every second counts.
With a capacity of 10+1 rounds, the FN 509 MRD Fullsize offers ample firepower housed within an expertly engineered platform that exemplifies reliability and craftsmanship synonymous with Fabrique Nationale Herstal's legacy.
