Built specifically for the MOS versions of the Glock 43X and 48, this Trijicon HD set is the answer for slim-frame carry guns wearing a micro red dot. The taller optic-height sights sit high enough to co-witness through most compact optics, so you keep a solid iron backup if the dot ever goes dark or the battery dies at the worst possible time. Up front you get a yellow photoluminescent ring around a green tritium lamp, and the rear runs a blacked-out U-notch with its own tritium dots. That color combo is a favorite for a reason. The bright yellow front pops in daylight and the tritium keeps working long after the sun goes down.
Trijicon designed the HD line around fast front sight acquisition, and the wide yellow ring does the heavy lifting during the day. The front blade is taller and more prominent than stock sights, which pulls your focus exactly where it needs to be. When the light drops off, the green tritium takes over so you always have a defined aiming point. The blacked-out rear keeps your attention on that front dot instead of splitting it across three glowing lamps.
This is the newer MOS-specific configuration, so it is machined for the optic-ready slides on the 43X MOS and 48 MOS rather than the standard non-MOS models. The rear sight also carries a steep front hook that lets you rack the slide one-handed against a belt or boot heel if you ever need to. Green tritium lamps carry a 12-year warranty from the date of manufacture, so you can count on years of reliable glow without touching a battery.
These are steel sights with a matte black finish that hold up to hard use and heavy carry. Trijicon recommends professional installation, and a proper sight pusher makes the job clean and keeps everything zeroed. If you carry a slim Glock with a dot, this is one of the most worthwhile upgrades you can make to the platform.
No. This particular set (part 601163) is cut for the MOS versions of the 43X and 48 with the optic-ready slide. If you have a non-MOS 43X or 48, you will want the standard-height HD set instead, since these taller optic-height sights are meant to co-witness with a red dot.
Yes, that is the whole point of these taller sights. They sit at optic height so you can see your irons through most compact red dots mounted on the 43X MOS or 48 MOS. That gives you a reliable backup aiming point if your dot ever fails or the battery dies.
Trijicon warrants the green tritium lamps for 12 years from the date of manufacture. In real-world use they stay usefully bright for years, and there are no batteries to swap since tritium glows on its own.
Trijicon recommends professional installation, and it is smart advice. A proper sight pusher makes swapping the front and rear clean and keeps your point of impact where it should be, so a gunsmith or a good bench tool is the way to go.
