The Trijicon HD XR Night Sight set takes everything folks loved about the original HD line and dials in the precision. The big change here is a thinner front post that measures .122 inches wide, which opens up your field of view and lets you see more of the target and where your rounds are landing. That slimmer post is the whole point of the XR, giving you a cleaner sight picture for those longer, more deliberate shots without giving up the fast target pickup the HD series is known for.
Up front you get a photoluminescent orange outline wrapped around a green tritium lamp, and Trijicon caps that front dot with a domed sapphire window that focuses the glow for roughly twice the brightness of a standard lamp. The result is a front sight your eye snaps to in bright sun and pitch dark alike. Out back is an angled, serrated U-notch rear with a blacked-out outline, which is exactly what you want. Keeping the rear subdued lets that bright front dot dominate so you are not fighting to sort three equal dots when it counts.
These are tough sights. The tritium gas lamps sit inside protective aluminum cylinders with extra silicone rubber cushioning, so they shrug off heavy recoil and the harsh solvents that come with regular cleaning. Green tritium carries a 12-year warranty from the date of manufacture, so you are looking at years of dependable low-light glow before it starts to fade.
This particular set is cut for Glock large-frame models including the 20, 21, 29, 30, 36, 40, and 41, along with the S and SF variants. Worth noting these are not made for the MOS optic-cut platform, so if you run an MOS slide you will want a suppressor-height option instead. Installation is straightforward for anyone comfortable with the job, though the dovetails run snug on purpose. A proper sight pusher is the way to go here rather than a hammer and punch, since the tritium tubes can be damaged if you force them in wrong.
This set is cut for Glock large-frame pistols, specifically the 20, 21, 29, 30, 36, 40, and 41, including the S and SF variants. They are not compatible with MOS optic-ready slides, so if you run an MOS model you will need a suppressor-height set instead. Double-check your exact model before ordering.
The main difference is the front post. The XR uses a thinner .122 inch front post compared to the wider original, which opens up your field of view and lets you make more precise hits at longer distances. You keep the same bright, fast front dot but with a cleaner sight picture for deliberate shooting.
The green tritium lamps are warranted for 12 years from the date of manufacture. Tritium glow naturally dims over time as the gas decays, but you can count on strong, reliable low-light visibility for well over a decade before it starts to fade.
Yes, if you are comfortable working on your slide. The dovetails run snug by design, so a sight pusher is strongly recommended over a hammer and punch. Forcing them in the wrong way can crack the tritium tubes, so take your time or have a gunsmith handle it if you are unsure.
