This is Trijicon's HD XR Suppressor/Optic Height sight set (part number 601177), cut to fit large-frame Glock MOS pistols like the G20, G21, G29, G30, and G41 in their S and SF variants. The taller sight bodies do two jobs at once: they clear the added height of a mounted suppressor and give you a solid backup co-witness under a slide-mounted red dot like an RMR or SRO. When your optic goes dark or your can is in the way, these keep you shooting.
The HD XR line is built around a slimmer .122-inch front post. That thinner blade opens up the sight window on either side of your front sight, which means a wider field of view, faster target pickup, and cleaner precision when you're stretching things out to longer distances. The front features a domed sapphire cap over the tritium lamp that focuses the glow for a noticeably brighter aiming point, wrapped in a photoluminescent yellow ring that pulls your eye straight to the front in daylight. The rear is an angled, serrated U-notch with a blacked-out outline, which cuts glare and keeps your focus where it belongs.
The self-luminous green tritium lamps run completely battery-free, so there's nothing to charge or switch on before you need them. The yellow front outline and the tritium combine into an intuitive sight picture that reads fast in bright sun, at dusk, and in total darkness. Machined tough to take the recoil of a 10mm or .45 ACP slide, this set is made to hold zero through thousands of rounds.
Trijicon recommends professional installation with a sight pusher, since these are a press-fit dovetail setup and getting them seated and centered properly matters. The green tritium lamps carry a 12-year warranty from the date of manufacture, and the sight bodies themselves are backed by Trijicon's reputation for building gear the military, law enforcement, and serious pistol folks trust.
This set is cut for large-frame Glock MOS pistols, which covers the G20, G21, G29, G30, and G41 including the S and SF variants. These are the 10mm Auto and .45 ACP frames. Double-check your slide cut against your specific model before ordering to be sure it matches.
Yes. The suppressor/optic height bodies are tall enough to give you a backup co-witness through a slide-mounted red dot like a Trijicon RMR or SRO. They also clear the added height of a mounted suppressor, so they pull double duty for suppressed or optics-ready setups.
No batteries at all. The green tritium lamps are self-luminous and glow on their own, so they're always ready in low light with nothing to charge or turn on. Trijicon warranties the tritium for 12 years from the date of manufacture.
Trijicon recommends professional installation since these are a press-fit dovetail design that needs a proper sight pusher to seat and center correctly. A gunsmith or a good sight pusher tool will get them dialed in without marring the slide. Trying to drive them in with a hammer and punch is a good way to damage the sights or your slide.
