The Meprolight Tru-Dot Night Sights for Glock large frame pistols (S and SF), green front and orange rear, are a fixed tritium sight set (Meprolight part no. 102223301). Swiss-made tritium vials sit in both the front and rear sights, so there is no battery to replace and no charging, and the dots are always on. In daylight the Tru-Dot pattern gives you three bright white dots for fast target acquisition, and in low light the tritium takes over. This version pairs a green front with an orange rear, which makes the two sights easy to tell apart in a fast sight picture. The set is ultralight steel, built as a direct upgrade to factory sights, and Meprolight designs the Tru-Dot sets to fit all holsters.
