Description
Product Overview
The FN FNX-45 Tactical is a full-size .45 ACP semi-automatic pistol built around a durable polymer frame and a cold hammer-forged stainless steel barrel. Its 5.3-inch barrel uses .578x28 threads and includes a thread protector, providing suppressor compatibility. Interchangeable backstraps and textured grip panels help users tailor the fit and maintain control, while the low-bore axis helps reduce perceived recoil. The slide features front and rear cocking serrations, high-profile combat night sights, and an optic-ready mounting system. Ambidextrous safety, decocking, slide-stop, and magazine-release controls support left- or right-handed operation. This configuration includes a Viper red dot and two 15-round magazines.

I am very pleased with...
I am very pleased with the gun. I love the black powder color on it and the slickness. Easy to shoot and feels very good in my hands. It has strong body, providing me with the grip needed to handle business without hesitation. It is worth the money and a great investment. The load capacity is outstanding. Cons My gun came with a Vortex Viper sight on it, but it sits too low with regard the dovetail sighs, that is my opinion. Not exactly like the picture I saw before I bought it. It was missing a bottom plate and Vortex replaced it for me, very good customer service. But the mount plate Vortex gave me can't be attached to the gun, because the mounting plate supposed to be used to attach the sight to it is missing. The sight in the picture sits higher than on my gun and I can not find a mounting plate to attach the plate Vortex sent me. I can attach the sight to the mounting plate Vortex sent me, but I cannot attach these two to the gun itself, a base plate is missing I assume. Very disappointing.

This firearm is...
This firearm is exceptional. The red dot co witnesses with the suppressor height sights. Because its polymer it feels a little off with an empty magazine but the moment you load it it feels perfect. I would buy another in a moment but I won't have too because it's an FN.
