The XS Sights R3d 2.0 night sights for Glock 19 bring serious low-light capability to your carry gun without the learning curve or installation headaches. These second-generation sights are engineered around two things shooters actually care about: seeing your target fast in any light, and getting them installed without a gunsmith. The R3d 2.0 cuts installation force in half compared to the original, making a home sight swap realistic for most shooters—no specialized tools or expertise required.
What sets these apart is the dual-illuminated front sight. The tritium insert glows on its own in darkness, but the high-contrast photoluminescent ring charges in ambient light and delivers a visible glow dot even in dim conditions. That means you're not relying purely on tritium and hoping there's enough light to see your sights; you've got redundancy. The serrated, blacked-out rear sight cuts glare and forces your eye downrange to the bright front post—a simple geometry that works. The rear sight ledge is a bonus for shooters who run slides with one hand, whether you're at a match or clearing a room in your home.
Built tough for years of daily carry and range use, the black nitride finish resists corrosion and wear. Whether you shoot bright daylight stages, hunt at dusk, or need confident sight picture in a defensive scenario, these sights scale across the lighting spectrum. They're not guesswork—they're XS Sights' proven night sight platform refined for what Glock 19 owners actually demand.

The dual-illuminated design combines a tritium insert that glows in darkness with a high-contrast photoluminescent glow dot that charges in ambient light. This gives you a bright, visible sight picture even in dim conditions where tritium alone might be hard to see, and full brightness in daylight.
XS Sights engineered the R3d 2.0 for DIY installation. The sights require 50% less installation force than the first-generation R3d, making it realistic for most shooters to swap them at home using basic tools. Always follow proper safety procedures and check the manufacturer's installation guide.
