The FNX has a 10-round capacity of .45 ACP, effectively combining stopping power and capacity. The FNX-45 Tactical incorporates a 5.3” cold hammer forged stainless steel barrel threaded at 0.578x28 TPI for use with a compensator, silencer, or any other compatible muzzle device. Raised night sights are included, intended for easy use with a sound suppressor right out of the box.

The FNX-45 Tactical is an improvement on the design of the FN FNP-45 Tactical which was developed for the U.S. Joint Pistol Program in 2007. The FNX takes what FN learned in tailoring the FNP to strict military specifications, and uses it to create a truly battle-tested handgun.

The FNX ships with three 10-round magazines, making it compliant with large capacity magazine restrictions in states like Colorado, California, New York, and the District of Columbia. Four interchangeable backstraps mean the operator can quickly tailor the size of the grip to fit their needs for greater consistency and control over operation. The FNX’s low bore axis keeps felt recoil to minimum. Controlling the operation of the pistol is easy no matter which hand is used, as the slide lock mechanism as well as the safety levers are totally ambidextrous. The slide is serrated at the front and the rear for easy operation in all conditions, even while wearing gloves.

The barrel on the FNX-45 Tactical is threaded to accept suppressors, compensators, or any other appropriately sized muzzle device. To accommodate a suppressor, the FNX features a high-profile sighting system with Tritium illuminated 3-dot sights. Additionally, the slide features two mounting bases to accept a variety of pistol optics, such as the Trijicon RMR or other reflex sight. On the bottom of the frame, Picatinny rails are ready to add accessories such as a flashlight or laser.

The FNX-45 Tactical is a firearm that will stand up the toughest battles, day-in and day-out, for the long haul. It won’t just survive the fight, it’ll emerge victorious.
