FN FNX-45 Tactical: Purpose-Built Combat Handgun

The FNX-45 Tactical represents the evolution of FN's legendary combat pistol lineage. Born from the U.S. Joint Combat Pistol Program, this handgun was engineered from the ground up to perform under the most demanding conditions.

Design & Ergonomics

The FNX-45 features a low-bore axis that reduces felt recoil and enhances control during rapid fire. The checkered polymer frame provides a secure, non-snag grip with a natural point of aim that shooters appreciate immediately.

Key ergonomic features:

  • Four interchangeable backstraps for custom grip fit
  • Fully ambidextrous controls (safety, decocking lever, slide stop, magazine release)
  • Serrated trigger guard for positive indexing
  • Checkered and ribbed grip panels

Barrel & Accuracy

The 5.3-inch cold hammer-forged stainless steel barrel delivers the accuracy expected from a precision combat pistol. The threaded muzzle accepts suppressors, compensators, and other accessories—a critical feature for modern tactical applications.

Sights & Optics

High-profile combat night sights come standard for low-light performance. The optics-ready slide includes two mounting bases, allowing you to quickly install your choice of red-dot electronic sights without gunsmithing.

Magazine & Capacity

The precisely engineered 10-round magazine is designed for reliability and natural feeding. Two magazines ship with the pistol.

What's Included

  • Two 10-round magazines
  • Carrying case
  • Magazine locking device
  • Sight mounting kit with plates and screws
  • Four interchangeable backstraps

The FNX-45 Tactical is a serious tool for serious shooters—whether you're a law enforcement professional, military operator, or civilian committed to self-defense excellence.
