FN 545 Tactical .45 ACP 4.7" Threaded Black Optic Ready 18+1 66-101383

545 Tactical

The FN 545 Tactical is a high-capacity suppressor-ready pistol chambered in .45 ACP, featuring a 4.71-inch threaded barrel for seamless integration with sound suppressors and a massive 18+1 capacity that sets a new benchmark in big-bore carry firearms. It includes co-witness tritium night sights for low-light accuracy, an optics-ready slide for red dot mounting, and a precision-tuned trigger with approximately 6-pound pull for refined control. The black PVD finish and aggressive grip texture ensure durability and secure handling in any condition.

Delving deeper, the 545 Tactical incorporates a polished feed ramp for flawless feeding of .45 ACP ammunition, a double-action striker-fired mechanism with consistent pull, and a polymer frame with accessory rail for lights or lasers. The threaded barrel with .578×28 pitch allows easy attachment of suppressors, while the extended 18-round magazine provides unmatched firepower without sacrificing concealability. Ergonomics borrowed from the proven FN 509 Tactical make it comfortable for extended range sessions or daily carry.

This pistol is ideally suited for home defense, suppressed training, or as a duty sidearm where maximum capacity and reliability are essential. Its blend of big-bore stopping power, suppressor compatibility, and high shootability makes it perfect for professionals and enthusiasts demanding performance that outperforms traditional .45 platforms in dynamic scenarios.
