TruGlo TFX Pro FNX-40/FNP-40/FNS-40 Tritium Fiber Optic Sight Set - Black Nitride

The TruGlo TFX Pro is a premium day/night handgun sight set built specifically for the FNH FNP-40, FNX-40, and FNS-40 pistols, including the compact variants. Designed for shooters who demand 24/7 brightness without batteries, the TFX Pro combines the always-on glow of encapsulated tritium with the daylight brilliance of fiber optic inserts in a single, virtually indestructible capsule.

Construction centers on a CNC-machined steel body protected by TruGlo's signature Black Nitride Fortress Finish for outstanding wear and corrosion resistance. The encapsulated TFO capsule is impervious to gun oils, cleaning solvents, and ultrasonic cleaning baths, so the sights keep performing in the harshest range and duty environments. The compact, snag-free profile tucks cleanly against the slide for quicker, smoother draws.

Up front, a square post pairs green tritium with a fiber optic insert wrapped in a contrasting orange outline ring for fast daylight pickup and instant nighttime acquisition. Out back, a U-notch rear uses matching green tritium and fiber optic inserts to deliver a clean sight picture and improved low-light accuracy. The set extends sight radius and locks in faster target transitions in any lighting condition.

Purpose-built to enhance accuracy on your FN pistol, the TFX Pro installs as a direct replacement for factory sights and is engineered to deliver consistent, reliable point of aim whether you're shooting in daylight, low light, or total darkness.
