Frequently Asked Questions
Do these sights require batteries or need to be charged with a flashlight?
No. TruGlo Brite-Site Tritium sights are completely self-luminous. Tritium is a low-level radioactive gas sealed inside the sight inserts that glows on its own 24/7 — no batteries, no UV charging, and no external light source required. They are always ready, making them one of the most reliable choices for defensive carry.
Which Glock models are these sights compatible with?
The TruGlo Brite-Site Tritium Low (TG231G1) is designed to fit a wide range of standard-frame Glock pistols that use low-profile sight cuts. This typically includes popular models like the Glock 17, 19, 22, 23, 26, 27, and others in the standard sight height category. Always verify your specific model's sight height requirements before purchasing, or contact TruGlo directly for fitment confirmation.
How long will the tritium inserts stay bright?
Tritium has a half-life of approximately 12 years, meaning your sights will retain roughly half their original brightness after that period. In practical terms, TruGlo Brite-Site Tritium sights typically provide 10–12 years of useful, visible illumination under normal conditions — well within the lifespan of most defensive pistols and carry setups.
