FN FNX w/Optic 45 ACP 15-Round Semi-Automatic Handgun

Overview

The FN FNX with integrated optic is a high-performance .45 ACP semi-automatic handgun designed for demanding operational environments and precision applications. Engineered with a low-bore axis and fully ambidextrous controls, this platform is configured to mitigate felt recoil and optimize operator control. The inclusion of a factory-mounted Holosun 407C red dot sight, coupled with a threaded barrel, establishes the FNX as a versatile and adaptable system for enhanced targeting and accessory integration.

Key Features

Ergonomics & Control

The FNX’s checkered polymer frame features an aggressively textured grip, precisely molded for secure retention and efficient manipulation. The low-bore axis design is engineered to significantly mitigate felt recoil, enabling rapid follow-up shots and enhanced control during sustained fire. The grip angle is optimized to facilitate a natural point of aim, contributing to intuitive target acquisition.

Barrel & Muzzle Integration

This model is equipped with a 5.30-inch cold hammer-forged stainless steel barrel. The threaded muzzle (0.578×28 TPI) is specifically designed to integrate sound suppressors, compensators, and other muzzle accessories, expanding the firearm’s operational utility. Cold hammer forging ensures superior bore concentricity and extended service life under rigorous conditions.

Optics Integration

The robust stainless steel slide is factory-milled and includes two mounting bases, providing compatibility with various red-dot electronic sights. This specific configuration arrives with a Holosun 407C red dot sight pre-installed, offering immediate red dot sight benefits, including accelerated target acquisition and enhanced precision across diverse lighting conditions. The high-profile combat night sights are designed to co-witness or serve as backup iron sights.

Slide Construction & Sights

Constructed from stainless steel, the slide features deep front and rear serrations, ensuring positive manipulation during charging and press checks under all conditions. The integrated high-profile combat night sights provide reliable aiming in low-light environments and are designed to complement optic usage, maintaining situational awareness.

Ambidextrous Operation

All primary operating controls—including the manual safety/decocker, slide stop, and magazine release—are fully ambidextrous. This design feature ensures seamless and consistent operation for both right- and left-handed users, maintaining operational efficiency without requiring modifications.
