XS Sights R3D Night Sight Set for Glock 17-36 Suppressor Height 3-Dot Tritium Ember Glow Front Dot

Low-light shooting demands sights that work when ambient light fails. The XS Sights R3D Night Sight Set for Glock 17-36 in suppressor height delivers a combat-proven 3-dot tritium system engineered for fast target acquisition in darkness and daylight alike. Built for serious shooters who won't compromise on speed or accuracy whether you're running night drills at the range or carrying professionally, these sights combine tritium lamps with XS's Ember Glow Dot Technology—a self-illuminating front sight that absorbs ambient light and glows when the sun goes down.

The R3D design prioritizes sight picture clarity in ways that matter. The front blade runs narrower at 0.145 inches, while the rear notch opens to 0.170 inches wide, boosting front-sight visibility and reducing target-acquisition time. The blacked-out rear sight eliminates light scatter and frames your front sight crisply against any background. XS engineered the front tritium lamp brighter than the rear pair, so even in complete darkness you won't confuse front and rear vials—muscle memory stays sharp. Choose your color strategically: green tritium produces maximum glow intensity for pure low-light work, while orange delivers superior contrast in bright conditions while holding visibility in shadow.

At suppressor height, these sights co-witness lower-third with Glock factory-cut slides and RMR footprints, giving you mounting flexibility if you run a red dot. Installation is straightforward with a sight pusher tool or basic hammer-and-punch method—no gunsmith required, though some Walther PDP models may need minor file work for fit.

Frequently Asked Questions

Which front sight color should I choose—green or orange?

Green tritium produces the brightest glow intensity in low-light and no-light conditions, making it ideal for night shooting and low-light defensive work. Orange provides the best contrast in bright daylight while still maintaining visibility in shadow. Consider your primary shooting environment: if you work nights, go green; if you split your time between day and night, orange is the more versatile choice.

Will these sights work with my Glock and a mounted red dot?

Yes. These are suppressor-height sights that lower-third co-witness with Glock factory-cut slides and RMR-pattern optics, so they sit at the right height to be visible if your red dot fails or if you need iron sights quickly while running a mounted optic.

Do I need a gunsmith to install these sights?

No. They install with a sight pusher tool or a hammer and punch—basic tools most shooters have on hand. Note that some Walther PDP models may require minor filing for proper fit, but Glock installation is typically straightforward.

What makes the R3D brighter than standard night sights?

The front tritium lamp is engineered brighter than the two rear lamps, which serves two purposes: it speeds up your sight picture by naturally drawing focus to the front sight, and it prevents confusion in zero-light conditions where you might otherwise mistake a rear vial for the front. The Ember Glow technology on the front sight ring absorbs ambient light and glows independently of the tritium, adding to low-light visibility.
