Truglo Tritium Night Sights (High) Fits Glock 20 21 25 28 29 30 31 32 37 40 and 41 - Front Green/Rear Green

The Truglo Tritium Night Sights (High) for Glock 20, 21, 25, 28, 29, 30, 31, 32, 37, 40, and 41 deliver self-illuminating aiming capability without batteries or charging. Tritium phosphor technology glows continuously in darkness while maintaining standard white-dot visibility in daylight conditions, giving operators reliable target acquisition in low-light environments where secondary illumination is unavailable or impractical.

These sights feature CNC-machined steel construction with green front and rear tritium elements. The high profile design provides adequate clearance over standard Glock slides while maintaining compatibility with factory and aftermarket holsters. Tritium requires no external power source—the radioactive isotope emits light continuously through self-luminous decay, making these sights functional in complete darkness for years without maintenance or user intervention. The green-on-green sight picture offers enhanced contrast for most shooters compared to traditional three-dot configurations.

Truglo tritium night sights are standard equipment for law enforcement agencies, tactical teams, and armed civilians who demand immediate target identification in low-light scenarios—vehicle stops, building searches, home defense, and range training with transitional lighting drills. The fixed sight design eliminates adjustment complexity and potential zero shift during storage or transport, prioritizing reliability over adjustability.

Tritium night sight technology has served military and law enforcement platforms for decades. Unlike phosphorescent coatings that fade after charging, tritium maintains consistent luminosity regardless of light exposure, making it the preferred choice for duty weapons where visibility degradation is not an acceptable variable.
