The Meprolight Tru-Dot Night Sight Set (brand part number 0102203131) is a green tritium front and rear set on a Black frame, purpose-built for the Glock 42. Meprolight engineers the combat-proven Tru-Dot system for improved rapid, instinctive aiming that requires no transition from day to night use, since the three-dot reference stays identical in appearance and location under any light. Because it runs on tritium, there is no battery to replace and no charging required, and the rear sight is adjustable for windage.
