TruGlo TFO TG131NT2 1911 Government Novak Tritium/Fiber Optic Night Sight Set

The TruGlo TFO TG131NT2 combines bright daytime fiber-optic visibility with self-illuminating tritium for around-the-clock aiming on 1911 Government pistols. The set is built on a precision CNC-machined steel frame finished in Black Nitride Fortress and drops directly into standard Novak .270" x .450" dovetail cuts without gunsmithing.

The front features a clean square blade paired with a snag-resistant U-notch rear, both lit by green fiber optics with a 0.060" fiber diameter for fast daytime pickup. Encapsulated Swiss tritium vials in both front and rear take over in low light and total darkness, glowing continuously with no batteries or external light sources required. From bright sunlight to a dim indoor range, the TFO system delivers consistent sight acquisition.

Designed as a direct-fit replacement for 1911 Government pattern pistols with Novak Low Mount dovetails, the TG131NT2 brings the original Tritium + Fiber-Optic handgun sight concept to a carry or range pistol. The Black Nitride Fortress coating protects the steel frame from wear and corrosion through regular use.
