The FN America FN 509 Tactical is a full-size 9mm semi-automatic pistol built for duty, defensive, and suppressed applications. Its 4.5-inch threaded barrel supports compatible muzzle devices and suppressors, while suppressor-height night sights provide a clear sight picture above an installed suppressor. The low-profile optics mounting system allows the pistol to accept a compatible red dot sight without sacrificing its factory sighting system. A polymer frame, interchangeable backstraps, integrated trigger safety, and five included 10-round magazines complete this configuration.
