The FN 509 Tactical is a semi-automatic 9mm pistol designed for duty, defensive, and suppressor-ready applications. Its polymer frame supports a durable, practical build, while the 4.5-inch threaded barrel accepts compatible muzzle devices and suppressors. Suppressor-height night sights provide a clear aiming reference, and the FN Optics Mounting System allows the installation of a compatible red dot optic. This no-manual-safety configuration uses a striker-fired operating system with an integrated trigger safety. The package includes one 24-round magazine, one 17-round magazine, and an FN soft case.
