FN 545 Tactical .45 ACP

The FN 545 Tactical is a full-size, striker-fired .45 ACP pistol developed for duty, range, and tactical use. It is built to accept red-dot optics and to support suppressor-capable setups with a threaded barrel and suppressor-height sights.

The pistol pairs a polymer frame with a machined steel slide to deliver a balanced, durable platform. Ergonomic enhancements include interchangeable backstraps, an accessory Picatinny rail, and an optics-ready slide that accepts multiple mounting footprints without a gunsmith.
