Description

The Trijicon HD XR Night Sight Set takes everything folks liked about the original HD sights and dials in the precision. The big change is the front post. At just .122 inches wide, it's noticeably thinner than the standard HD's .150-inch post, so you get more daylight around the front sight and a wider view of what you're aiming at. That translates to a finer aiming point and less of your target hidden behind the sight, which really shows up when you stretch things out past normal defensive distances.

This set fits Glock large-frame pistols including the 20, 21, 29, 30, 36, 40, and 41, along with S and SF variants. It does not work with MOS models, so keep that in mind if you're running an optics-ready slide. The front sight wears a photoluminescent yellow outline that soaks up light and stays visible in daylight, while the green tritium lamp underneath is capped with a domed sapphire jewel that focuses the glow for a front dot roughly twice as bright as the older HD front sight. The rear is a blacked-out U-notch, angled and serrated to cut glare and keep your eye pulling toward that front sight where it belongs.

Why Riflemen and Duty Shooters Reach for the HD XR

Trijicon built this line with law enforcement and competition in mind, and it earns that reputation. Reviewers who've run both the HD and HD XR consistently point to the thinner post as the reason the XR feels more precise, especially at distance. Up close you still get a fast three-dot layout, but the trade is a sight picture that rewards a little more front-sight focus.

Living With the HD XR Night Sight Set

The tritium is warranted for 12 years from the date of manufacture, so you're covered for a long stretch of no-battery, always-on low-light aiming. These are steel-bodied, drift-adjustable sights built to take the beating of daily carry and range time. Professional installation with a sight pusher is the way to go here, since pistol sights are pressed into dovetails and a proper tool keeps everything square and damage-free.

Frequently Asked Questions

What Glock models does this HD XR night sight set fit?

This set is made for Glock large-frame pistols including the 20, 21, 29, 30, 36, 40, and 41, plus the S and SF variants. It is not compatible with MOS optics-ready models. If your slide is cut for a red dot, you'll want a different setup.

How is the HD XR different from the standard Trijicon HD sight?

The main difference is the front post width. The HD XR uses a thinner .122-inch front post versus the .150-inch post on the original HD, which gives you a wider field of view and a more precise aiming point. Many people find the XR shines at longer distances while the standard HD is a touch faster to pick up at close range.

How bright is the front sight and how long does the tritium last?

The green tritium front lamp sits under a domed sapphire cap that focuses the glow, making it roughly twice as bright as the standard HD front dot. The yellow photoluminescent outline also charges up in daylight so it stays visible without light. Trijicon warranties the tritium for 12 years from the date of manufacture.

Can I install these HD XR sights myself?

Trijicon recommends professional installation, and for good reason. Pistol sights press into dovetail cuts and really need a proper sight pusher to seat squarely without marring the sight or slide. A gunsmith can knock this out quickly if you don't have the tools.
