The TruGlo Tritium Night Sight Set (brand part number TG231G2) keeps a Glock sighted in even when the lights go out, transitioning from a standard white-dot sight picture in daylight to glowing green dots after dark. TruGlo adds a FOCUSLOCK ring to the front sight for even faster focus acquisition, and because tritium is self-illuminating, there are no batteries to replace and nothing to charge. Sized to fit most standard holsters, this set is compatible with the Glock 20, 21, 25, 29, 30, 31, 32, 37, 40, and 41, excluding MOS-cut models.
