Built on the proven and popular FNS Compact design the FN-509 was built to meet the US Army's Modular Handgun System requirements. FN developed this platform with the help of industry experts and exhaustive testing of more than a million rounds. Now FNH has taken this fantastic handgun to the next level with the FN-509 Tactical. It's a combat gun with a threaded barrel for your suppressor, fully ambidextrous controls, and no safety to get in the way. This durable pistol has front and rear cocking serrations, interchangeable back straps and suppressor height night sights. The stainless steel slide features the FN Low Profile Optics Mounting System to install and co-witness your choice of more than 10 popular MRD's or miniature red dots (sold separately). It sports an ergonomic polymer frame that is more than tough enough to take anything you can throw at it. The FN-509 Tactical represents the next generation of FNH handguns! Get yours today!
