FN FNX-45 Tactical .45 ACP 5.3" Threaded Barrel

FN FNX-45 Tactical: Purpose-Built Combat Performance

The FNX-45 Tactical represents the evolution of FN's legendary combat pistol lineage. Developed from the proven FNP-45 platform, this handgun combines battle-tested engineering with modern tactical features.

Design Philosophy

This is a pistol built for serious work. The low-bore axis reduces felt recoil and improves control, while the ergonomic polymer frame naturally guides your hand to the target. Every control surface—from the checkered grip panels to the serrated trigger guard—is designed for reliable operation under stress.

Mechanical Excellence

Slide & Barrel:

• Stainless steel slide with front and rear cocking serrations
• Cold hammer-forged stainless steel barrel with polished chamber and feed ramp
• 5.3" threaded barrel (0.57x28 TPI) accepts suppressors, compensators, and other muzzle devices
• Thread protector included
• Slide is cut and drilled for optional red-dot electronic sights

Frame & Controls:

• Polymer construction with replaceable steel frame and slide rails
• Fully ambidextrous decocking/safety lever, slide stop, and magazine release
• MIL-STD 1913 Picatinny rail for tactical accessories

Sights & Optics Compatibility

High-profile combat night sights are factory-installed for suppressor-height use. The slide includes two mounting bases to accept multiple styles of optional red-dot electronic sights, allowing you to configure the pistol for your specific mission.

Magazines & Capacity

Two 15-round magazines come standard. Each magazine features a polished body, low-friction follower, and polymer base pad. The engineering is precise—the magazine naturally orients toward the target when deployed to the prone position.
