The XS Sights R3D Night Sights are a 3-dot tritium notch-and-post sight set designed for a broad range of Glock pistols. The system combines tritium vials front and rear with XS’s Ember photoluminescent ring on the front sight to improve visibility in low light while preserving daytime contrast. CNC-machined steel construction and a blacked-out rear enhance sight definition and long-term durability. These sights are intended for everyday carry, service, and general-purpose shooting where reliable low-light indexing is important.

The R3D set focuses on a clear front sight target with a brighter front tritium lamp relative to the rear vials, while the Ember ring absorbs ambient light to provide supplemental photoluminescent contrast. The blacked-out rear and anti-reflective features reduce distraction from glare, and the rear ledge aids one-handed slide manipulation. Built from CNC steel, the R3D is sized and shaped to work with common holsters and everyday carry configurations.
Reliable, low-light capable sights that prioritize front-sight focus and durable materials make the XS Sights R3D a practical upgrade for Glock owners seeking improved sight visibility in a range of lighting conditions.
