TruGlo TG231F1W Tritium Pro FN FNP-9/FNX-9/FNS-9 Green Tritium Night Sight Set

The TruGlo TG231F1W Tritium Pro night sight set delivers reliable low-light aiming for FNH FNP-9, FNX-9, and FNS-9 pistols, including compact variants. Purpose-built for handgun carry and defensive use, these tritium sights transition from a white-dot daytime picture to glowing green dots in the dark, and require no batteries or prior light exposure to glow.

The front/rear set pairs a square front blade with green tritium lamps framed by a white outline ring against a U-notch rear with two green tritium lamps, giving a classic three-dot pattern that draws the eye quickly under stress. The sight bodies are CNC-machined from steel and finished in TruGlo's Black Nitride Fortress Finish for corrosion resistance and a clean, snag-free profile on the slide.

Designed specifically for the FNH FNP-9, FNX-9, and FNS-9 family, this sight set drops into the factory dovetails for a secure, low-profile install. Whether you are running a duty, carry, or home-defense FN 9mm pistol, the Tritium Pro delivers dependable low-light target acquisition without the bulk or battery dependency of an electronic optic.
