The TruGlo Tritium Pro Night Sight in a white outline (brand part number TG231G1AW) 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 Glock 42, 43, 43X, and 48 pistols, except MOS-slide models.
