FN Herstal 545

The FN 545 Tactical is a rugged, full-featured .45 ACP handgun built for serious performance in any scenario. Featuring a 4.1-inch threaded barrel, this pistol is suppressor-ready out of the box and delivers the heavy-hitting power of .45 Auto in a modern, modular platform.

At the core of the FN 545 is its optics-ready slide, designed to accommodate most leading red dot sights thanks to FN’s patented Low-Profile Optics-Mounting System. Paired with suppressor-height night sights, it offers a co-witness-ready sight picture for fast, intuitive aiming.

Built on a polymer frame with aggressive grip texturing and interchangeable backstraps, the FN 545 provides excellent control and comfort. Ambidextrous controls—slide stop and magazine release—make it fully adaptable for left- or right-handed shooters. With a 15+1 round capacity, it's one of the highest-capacity .45 ACP pistols available.
