About this product

The FN 545 Tactical is a full-size .45 ACP pistol built for duty and range use, featuring a suppressor-ready threaded barrel and an optic-cut, serrated steel slide. It pairs a polymer frame with a MIL-STD-1913 Picatinny rail and interchangeable backstraps for tailored ergonomics. The slide is configured for MRD optics and the pistol ships with night sights sized for suppressor-height co-witnessing. Controls are ambidextrous to suit a wide range of shooters.
