The FN 509M 9mm Luger with 4" target crown barrel brings FN’s proven duty-ready design into a balanced midsize package. This Flat Dark Earth model pairs a stainless steel serrated slide with a textured polymer frame and integrated Picatinny rail, giving shooters a controllable, modern sidearm with 15+1 capacity and ambidextrous controls.

Designed around everyday carry and range use, the 509M offers interchangeable backstrap grips to fine-tune the fit, plus a loaded chamber indicator for quick status checks. Its midsize dimensions help it conceal more easily than a full-size pistol while still providing a full firing grip and sight radius for confident defensive shooting or extended training sessions. FN’s long history of service pistols shows through in the 509M’s thoughtful ergonomics and reliable striker-fired performance.
