The TruGlo TFO Tritium/Fiber Optic Sight Set for the 1911 Government (brand part no. TG131NT1Y) pairs a green fiber-optic and tritium front sight with a yellow fiber-optic and tritium rear sight, giving shooters a consistently bright sight picture in daylight or complete darkness. TruGlo pioneered bringing fiber optics to the shooting sports industry, and this TFO line combines that daylight-gathering fiber-optic brightness with the same tritium technology used in genuine night sights, so the sight picture stays bright around the clock rather than fading indoors or after dark. Assembled in the USA using Swiss tritium, this set uses a snag-resistant design built to fit standard holsters without catching on the draw. It’s cut to fit 1911 models with a Novak LoMount-pattern cut, including the 5-inch Government model in .45 ACP, as well as Ruger SR1911 models with a fixed rear sight.
