TruGlo TFO TG131NTI Green Tritium/Fiber Optic Night Sight Set 1911 Government Novak .260/.450

Upgrade your 1911 Government with the TruGlo TFO TG131NTI night sight set, which pairs fiber-optic daytime illumination with tritium night visibility in a single, self-illuminating package. The TFO (Tritium + Fiber-Optic) design collects ambient light during the day through the fiber-optic elements, then transitions seamlessly to a steady green tritium glow as light fades - with no batteries and no switches to flip.

Purpose-built for the 1911 Government platform, this set drops into the Novak LoMount cut found on most duty, defensive, and custom 1911s (front footprint .260 inch, rear .450 inch). The square front blade pairs with a U-notch rear for a clean, intuitive sight picture and fast follow-up shots, while the matching green fiber-optic and tritium elements on both front and rear give you a high-visibility aiming reference in any lighting condition.

The sight frame is CNC-machined from steel and finished in TruGlo's Black Nitride Fortress coating for wear and corrosion resistance. Assembled in the USA around quality Swiss tritium, the TFO TG131NTI is purpose-built as a dedicated pistol night sight for 1911 Government pistols.
