The XS Sights R3D 2.0 night sights for Glock 19 bring suppressor-height positioning and dual-illuminated tritium technology to your carry gun. Built for shooters who run suppressors, these sights sit tall enough to cowitness with your optic or stand on their own for fast, reliable target acquisition in any light. The second-generation design improves on the original with easier installation—requiring 50% less force to mount—and a brighter sight picture that cuts through daylight glare and performs when the sun goes down.

The front sight combines tritium and photoluminescent elements for redundant illumination: tritium glows continuously without battery dependency, while the photoluminescent glow dot charges in daylight and adds brightness in low-light conditions. That dual approach means you're never caught without a sight picture. The rear sight is a classic blacked-out, serrated design that forces your eye downrange and eliminates reflections—the anti-glare surface won't compete with your front sight for attention.

If you're running a suppressor on your 19 and want night sights that won't cost you cowitness capability, these are engineered for that exact mission. The black nitride finish is durable enough for years of EDC use, and the suppressor height is purpose-built so you can mount an optic and still have usable iron sights underneath. For shooters who demand reliability and low-light capability without batteries, the R3D 2.0 delivers on both counts.
