The cold-hammer-forged stainless steel barrel measures 5.3 inches and is threaded .578-28 TPI, ready for most popular .45 caliber suppressors or compensators. A knurled thread protector is installed from the factory.
FN machines the slide from stainless steel and finishes it in durable FDE PVD. Front and rear cocking serrations offer positive purchase, while the factory optic cut accepts popular red-dot footprints using the included steel mounting plates.
Sights are suppressor-height tritium 3-dots that co-witness with most mini red dots. The raised profile ensures a clear sight picture over a suppressor and glows in low-light conditions.
Controls are fully ambidextrous: manual safety/decocker levers, slide stop, and magazine release all mirror on both sides. The magazine release is also reversible for additional user preference.
Inside, the FNX-45 Tactical runs a proven DA/SA system with an exposed rounded hammer. Combined with a MIL-STD-1913 accessory rail and interchangeable backstraps, the pistol adapts easily to mission, hand size, and accessory requirements. Original MSRP is listed at $1,379.
