The TruGlo Tritium Pro Night Sight in a white outline (brand part number TG231N1W) transitions from a standard white dot sight picture in daylight to a glowing green dot after dark, so you get one sight that works in both. The front sight uses green tritium with a white outline and a FOCUSLOCK ring for even faster visual focus, while the rear uses a plain green tritium dot. TruGlo assembles every set in the USA with Swiss tritium for maximum brightness, and because tritium is self-luminous, there’s no battery to replace and nothing to charge. It fits 1911 5-inch Government .45 ACP pistols and Ruger SR1911 models with a fixed rear sight.
