FN FNX-45 Tactical | .45 ACP 5.3″ Threaded | 15+1 | 66966

The FN FNX-45 Tactical is a full-size, optic-ready semi-automatic pistol chambered in .45 ACP featuring a 5.3 inch cold hammer-forged stainless steel threaded barrel and high-profile night sights. The pistol has a matte black polymer frame with interchangeable backstraps and fully ambidextrous controls including a decocker/safety, slide stop, and magazine release. It ships with two 15-round magazines and includes mounting bases to accept multiple red-dot footprints.

For a reliable optic under $1,000 that pairs well with this platform, consider a compact red-dot such as a Holosun model in an RMR-style footprint; the FNX-45’s multiple-footprint mounting system supports common pistol red-dot footprints while keeping cost well below the $1,000 threshold.

Recommended applications: competition-style pistol shooting and suppressed or precision-focused range work where the threaded barrel and raised sights assist in sighting with a suppressor or compensator.
