The FN 545 Tactical is a suppressor-ready, striker-fired pistol chambered in .45 ACP and built around the proven ergonomics of the FN 509 Tactical. Its 4.7-inch threaded barrel supports compatible sound suppressors, while co-witness tritium night sights provide a visible aiming reference in low-light conditions. The optics-ready slide accepts a wide range of red dot sights through the included MRD mounting plates. An integrated trigger safety, high-endurance striker, approximately 6-pound trigger pull, and interchangeable backstraps provide a practical balance of controls, durability, and fit.
