Frequently Asked Questions
Which Glock models are compatible with these R3D suppressor height sights?
The XS Sights R3D Suppressor Height sights are designed to fit a wide range of small-frame Glock pistols, including popular models like the Glock 17, 19, 26, 34, and their Gen 1–5 variants. They are also compatible with MOS (Modular Optic System) models. Always verify fitment against XS Sights' official compatibility chart or contact XS Sights directly to confirm your specific model before purchasing.
Will these sights co-witness with my red dot optic?
Yes — the suppressor height design of the R3D sights allows them to co-witness with select red dot optics mounted on MOS-compatible Glock slides. Whether you achieve absolute or lower-third co-witness depends on the specific optic and mount height you're using. These sights are an excellent backup iron sight option for red dot-equipped Glocks.
How long does the tritium illumination last, and does the orange dot glow without light?
Tritium inserts have a half-life of approximately 12 years, meaning your sights will remain functional for well over a decade before any noticeable dimming occurs. The orange photoluminescent glow dot works by absorbing ambient light — whether from sunlight, indoor lighting, or a flashlight — and then radiating that stored light in dark environments. This gives you bright, reliable visibility from multiple light sources, not just the tritium alone.
