Frequently Asked Questions
Will these TFX sights fit my specific Glock model?
These sights are designed for the "High" profile configuration on compatible Glock pistols. Most full-size and compact Glock models share the same dovetail dimensions, but it's important to confirm your specific Glock generation and model number before purchasing. When in doubt, consult the Truglo fitment guide or contact us at Goodland Guns — we're happy to help you find the right match.
How bright are tritium sights, and will they work in total darkness?
Yes — tritium is a self-luminous radioactive isotope that glows continuously without requiring any external light source or charging. The TFX sights combine this always-on tritium glow with a fiber-optic element that harvests ambient light during the day for exceptional brightness. In low-light or total darkness, the tritium provides a clear, usable aiming point, making these sights a top choice for home defense and duty use.
How long do the tritium inserts last, and is the sight durable enough for heavy use?
Tritium has a half-life of approximately 12 years, meaning your TFX sights will remain clearly visible for well over a decade of regular use before any noticeable dimming occurs. The illuminating elements are encased in a virtually indestructible chemical- and shock-resistant capsule, and the CNC-machined steel body is treated with Truglo's FORTRESS FINISH™ to resist rust, corrosion, and the rigors of daily carry or range use.
