Tapco Glock Tritium Sight Features The Tapco Tritium Sight uses a tritium insert that stays illuminated continuously giving shooters a consistently visible aiming point in low light or complete darkness without needing to pre-charge the sight. Surrounding the tritium vial is a daylight-fluorescing material that enhances visibility in bright conditions helping the sight stand out clearly against the target even in direct sunlight. This dual approach to visibility means the sight performs reliably whether the shooter is training at an outdoor range at midday or facing a defensive encounter at night. A steel frame construction ensures the sight holds up to the recoil and wear of regular use without shifting out of alignment. Designed to fit a broad range of Glock models including the 17 19 22 through 28 31 through 35 37 through 39 45 and 48 this sight set gives Glock owners across multiple calibers and frame sizes a single consistent upgrade option. The black finish matches factory Glock sight coloring keeping the sight picture clean and familiar for shooters transitioning from stock sights. Faster sight acquisition in both day and night conditions can make a meaningful difference in both competitive shooting and personal defense scenarios. For Glock owners seeking dependable around-the-clock visibility the Tapco Tritium Sight offers a straightforward broadly compatible upgrade.
