The Meprolight Tru-Dot Front Sight (brand part number 102243107) is a self-illuminated tritium front sight built for Glock Gen 1-5 pistols, sold as the front sight only. Meprolight’s combat-proven Tru-Dot system uses a green tritium vial ringed in a white outline, giving you a sight reference that looks and performs identically day or night with no transition needed as light fades. Because it requires no battery or light-charging, it’s ready to use the moment it’s installed, with only minor modification needed to mount it as a direct replacement for the factory front sight. Pair it with a Meprolight Tru-Dot rear sight to complete the full three-dot night sight picture.
