Frequently Asked Questions
Will the XS R3D Night Sights fit my Glock 43 without modification?
Yes. The XS R3D Night Sights are designed as a direct drop-in replacement for the factory sights on the Glock 43. They use standard Glock sight dimensions and are compatible with most OEM and aftermarket holsters designed for the G43. Installation typically requires a Glock sight tool or a professional gunsmith for proper seating and torque.
How do the Ember® Glow Dot and tritium work together?
The Ember® Glow Dot is a photoluminescent material that surrounds the front tritium lamp. During the day or in ambient light, the Ember dot absorbs and stores light energy, making the front sight highly visible without any tritium activation. In low-light or dark environments, the tritium lamp charges the Ember material from within, producing a front sight that glows noticeably brighter than the tritium-only rear sights — naturally drawing your eye to the front for faster target acquisition.
How long do tritium night sights last, and what does the warranty cover?
Tritium has a half-life of approximately 12 years, so XS R3D sights will provide reliable self-illumination for well over a decade under normal use. XS Sights also backs these sights with a 10-year no-questions-asked warranty covering defects in materials and workmanship. If your sights fail for any reason within that period, XS Sights will repair or replace them — making these a confident long-term investment for your Glock 43.
