Description
The FN 509 MRD (Micro Red Dot) in 9mm Luger is a purpose-built, optics-ready striker-fired pistol designed for shooters who demand reliability, versatility, and modern features at a competitive price. Chambered in 9mm and featuring a 3.8-inch barrel, this full-size polymer-framed pistol is ready for duty, home defense, or competition right out of the box.
The optics-ready slide features an RMSC footprint, allowing direct mounting of popular micro red dot sights without adapters. Standard green fiber optic front sight and a rounded U-notch rear sight provide a fast, intuitive sight picture when shooting iron. The accessory rail lets you add a light or laser for a complete defensive setup.
Built with safety in mind, the FN 509 MRD includes a firing pin block and trigger safety. The reversible magazine release and ambidextrous controls make it compatible with left- and right-handed shooters alike. The all-polymer frame and slide finish keep weight at just 22.5 ounces, making it comfortable to carry and easy to handle.
This package includes one 24-round and one 16-round magazine, giving you maximum capacity options from the start.
