Description
The Trijicon HD XR Night Sights take the proven HD design a step further, built for people who want to identify their target and put rounds where they're looking at greater distances. The front sight uses a thinner post ringed in yellow photoluminescent paint around a green tritium lamp, which opens up your field of view so you can see more downrange and read your hits faster. Out back you get a wide U-notch rear with two green tritium dots, giving you an intuitive sight picture that lines up quick under pressure.
Why the HD XR Front Post Works So Well
That slimmer front blade is the whole story here. A narrower post means less of the target hidden behind your sight, which matters a lot when you're stretching things out past close range or trying to identify what you're pointing at in low light. The bright yellow ring pulls your eye to the front sight during the day, and once the sun drops, the tritium takes over and glows without any batteries or charging. It's a setup that transitions cleanly from bright daylight to pitch black.
Built Tough Like You'd Expect From Trijicon
Durability is where these earn their keep. Each tritium lamp sits cushioned in silicone rubber and sealed inside an aluminum cylinder, so the glow survives the recoil and the bumps that come with real carry and range use. The housings are steel with a matte black finish, and the green tritium is warranted for 12 years from the date of manufacture, so you're getting a long service life out of the box.
Fitment for the HD XR Glock Set
This particular set covers standard-frame Glocks including the 17, 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, and 39. Do note these are cut for standard slides and not the MOS platform. The rear tends to fit snug in the dovetail, so a proper sight pusher and taping your slide will save you some grief during install. If you're not comfortable driving sights yourself, it's worth having a gunsmith handle it.

Frequently Asked Questions
Will these Trijicon HD XR sights fit my Glock?
This set is cut for standard-frame Glocks, covering the 17, 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, and 39. They are not made for the MOS optics-cut platform or the large-frame Glocks like the 20, 21, 29, 30, and 41. Double-check your exact model before ordering to make sure you're getting the right cut.
Do the HD XR night sights need batteries to glow?
No batteries at all. The green tritium lamps are self-illuminating and glow on their own in the dark, so there's nothing to charge or replace. The tritium is warranted for 12 years from the date of manufacture.
What makes the HD XR different from the standard Trijicon HD sights?
The main difference is the front sight post, which is thinner on the XR. That slimmer blade gives you a wider field of view so you can identify targets and see your hits better at longer distances. If precise engagement at extended range matters to you, the XR is the upgrade over the standard HD.
Are these hard to install?
The rear sight fits pretty snug in the dovetail, so most people use a quality sight pusher to seat it. Taping the sides of your slide helps keep the finish from marring during the process. If you're not set up for the job or aren't comfortable driving sights yourself, having a gunsmith install them is the easy route.
