Frequently Asked Questions
How does the Ember Glow Dot Technology work, and why is it better than standard tritium sights?
Ember Glow Dot Technology works by absorbing ambient light during the day and storing it to glow in low-light or dark conditions — similar to how a glow-in-the-dark material works, but significantly more advanced. What makes it superior to standard tritium sights is the combination effect: the tritium lamp inside the front sight continuously charges the Ember dot, meaning the front sight glows brighter than the rear sight at all times. This hierarchy of brightness keeps your eye naturally focused on the front sight and downrange target, which is exactly where your attention needs to be for accurate, fast shooting.
Are these night sights compatible with my existing holster?
Yes — XS R3D Night Sights are designed to fit standard holster profiles for Sig Sauer and Springfield XD pistols. Unlike some tall or suppressor-height sights that can snag or fail to fit OEM-spec holsters, the R3D sights maintain a standard profile that works with the vast majority of duty, concealed carry, and range holsters already on the market. If you use a custom-molded holster, verify with your holster manufacturer that the profile accommodates upgraded iron sights.
How long will the tritium in these sights remain effective?
Tritium is a radioactive isotope that naturally decays over time, with a half-life of approximately 12 years. For XS R3D Night Sights, you can expect full brightness performance for roughly 10–12 years under normal use. After that point, the tritium glow will gradually diminish, though the Ember Glow Dot will still absorb and emit ambient light. XS Sights backs these sights with a 10-Year No-Questions-Asked warranty, giving you confident coverage for the effective life of the tritium vials.
