Trijicon HD XR Night Sight Set for Glock 20/21/29/30/41 - Steel Matte 3-Dot Tritium Green

The Trijicon HD XR night sight set brings next-level low-light pistol performance to your Glock 20, 21, 29, 30, or 41. Built on the proven foundation of Trijicon's HD sights but refined for shooters who demand faster target acquisition and precision engagement at distance, the HD XR combines self-illuminating tritium with a purposefully thinner front sight post. That design choice isn't cosmetic—it opens up your sight picture, lets you spot targets and track hits more clearly in any light, and keeps you steady when precision matters.

If you carry a full-size or subcompact Glock and want iron sights that work as hard in darkness as they do in daylight, these are built for that job. The classic 3-dot tritium configuration glows green without batteries, giving you instant sight acquisition in low light while maintaining the same manual of arms you already know. Law enforcement agencies drove the development of this platform, which means the engineering reflects real-world demands—not just bench testing.

Trijicon backs the green tritium lamps with a 12-year warranty from manufacture, so you can trust these sights to stay bright through seasons of use. Steel construction in matte finish resists glare and handles the wear that comes with a working gun.

Frequently Asked Questions

What Glock models do these sights fit?

The HD XR night sight set fits Glock 20, 21, 29, 30, and 41, including S and SF variants of those models.

How long do the tritium lamps stay bright?

Trijicon warranties the green tritium for 12 years from the date of manufacture. Tritium naturally decays over time, but these sights will remain visible well beyond the warranty period.

Do I need batteries for these sights to glow?

No. The tritium is self-illuminating and requires no batteries, external light source, or charging. They glow continuously, day and night.

How does the thinner front sight post improve shooting?

The narrower front post gives you a larger sight picture, making it easier to spot targets, track your hits, and maintain sight alignment at distance—all without sacrificing precision or the ability to shoot in low light.
