XS Sights R3D Night Sight Set for Glock 17-36 Suppressor Height 3-Dot Tritium Ember Glow Front Dot$103.99 – $108.53
Availability: In Stock
The XS Sights R3D night sight set brings reliable tritium illumination to your Glock 17–36, engineered to keep your front sight sharp in any light. Built on the proven 3-dot notch-and-post geometry, these steel sights pair traditional tritium vials with XS Sights' proprietary photoluminescent glow dots—available in orange or green—that absorb ambient light and maintain visibility when the sun goes down. Whether you're training after hours, responding in low-light conditions, or simply want a sight picture you can trust in darkness, the R3D delivers the speed and clarity serious shooters demand.
The design philosophy is straightforward: keep your focus downrange. The front sight uses a brighter tritium vial and benefits from the tritium's own glow charge to make the ember dot shine more prominently than the rear pair. This intentional brightness hierarchy locks your eye on the front sight for faster, more accurate sight picture acquisition. The rear sights are blacked out with two tritium vials that illuminate just enough to confirm proper alignment without stealing focus from the front.
XS Sights machines these from steel and finishes them in durable black, built to handle the rigors of duty carry, sport shooting, and home defense. The sight geometry is compatible across the Glock 17 through 36 lineup, making this a straightforward upgrade path for most common Glock platforms.

XS Sights uses a brighter tritium vial in the front and lets the tritium's own light charge the glow dot slightly. This design keeps your eye focused on the front sight for faster, more accurate target acquisition without the rear sights outshining the front.
