The FN 545 Tactical is a suppressor-ready .45 ACP pistol built around the proven ergonomics of the FN 509 Tactical platform. Its 4.7-inch threaded barrel supports suppressor use, while co-witness tritium night sights provide a clear aiming reference in low-light conditions. The optics-ready slide accepts a wide range of red dot sights using the included MRD mounting plates. A high-endurance striker and crisp trigger pull of approximately 6 pounds support consistent operation, while two interchangeable backstraps help users tailor the grip to their hand. This FDE/Tan model includes two 10-round magazines.
