The FN 509 MRD delivers enhanced accuracy potential with its factory-installed optics mounting system and proven striker-fired reliability. This full-size pistol combines FN's military-grade construction with civilian-friendly ergonomics for serious shooters who demand precision.
What Makes This Different
The MRD (Modular Reference Design) variant stands apart with its pre-machined slide that accepts popular red dot optics without additional gunsmithing. Unlike standard pistols requiring aftermarket modifications, the 509 MRD ships ready for immediate optic installation. The low-profile iron sights co-witness perfectly with mounted optics, maintaining backup capability while maximizing sight radius.Key Features
