XS Sights R3D 2.0 Night Sights for Glock - 3-Dot Green Tritium Orange Outline Front / Green Tritium Rear

Upgrade your Glock pistol with the XS Sights R3D 2.0 Night Sights, a second-generation tritium sight set engineered to deliver a brighter, more durable aiming picture day or night. Built on a CNC-machined steel body with a black finish, this 3-dot tritium set pairs a square front post with a notched rear blade for a familiar notch-and-post sight picture that draws the eye to the front sight fast.

The front sight features green tritium wrapped in a high-contrast orange outline ring for rapid daylight acquisition, while the rear sight carries green tritium lamps on each side of the notch. The R3D 2.0 rear is engineered to be 50% brighter than the previous generation, and the blacked-out rear blade increases contrast against the front post to speed up target transition in low light. The dual-illuminated front combines a glow-dot ring with the tritium vial so the sight remains visible in any lighting condition.

Designed for defensive and carry use, the R3D 2.0 installs using XS Sights' EasyPress system, requiring roughly 50% less force than standard sight press installs with no filing or hammering needed. This set is purpose-built to fit Glock 17, Glock 19, and Glock 22 pistols, making it a direct replacement for factory sights on some of the most popular Glock duty and concealed-carry platforms.
