Description
The TruGlo TFO TG131NT4 is a green tritium and fiber optic front/rear handgun sight set purpose-built for 1911 Officer (3″ barrel) and Commander (4.25″ barrel) models that use the Novak Lo-Mount dovetail pattern with a .270″ front / .500″ rear sight height.
TruGlo pairs a daylight-bright fiber optic pick-up with a self-illuminating tritium vial in each blade, so the same three green aiming dots guide the eye under any light condition. The front uses a square post and the rear uses a U-notch configuration, with a 0.060″ fiber diameter on the front rod. The sight body is CNC-machined from steel and finished in Black Nitride Fortress for a hard, corrosion-resistant surface built for everyday carry.
Slides with an existing fixed Novak-style dovetail accept this set, though some fitting may be required. Designed specifically to enhance accuracy on 1911 pistols, this drop-in upgrade brings reliable low-light aiming performance to a classic carry platform.
