The Meprolight Tru-Dot set gives your Glock three tritium dots that glow on their own, day or night, no batteries and no switches to fuss with. The green front dot pairs with two green rear dots flanking a U-shaped notch, and when all three line up you know you're on target. During daylight the front sight carries a white outline for contrast, so these work just as well at the range at noon as they do in a dark room. It's a fixed, non-adjustable set built for fast, instinctive aiming when you don't have time to think about it.
Tritium is the key here. It's a self-contained light source that keeps producing that green glow around the clock without ever needing to be charged by a flashlight or sunlight like some cheaper phosphorescent sights. Meprolight backs the illumination with a 12-year warranty, and plenty of longtime users report their Tru-Dots still burning bright well past a decade of daily carry. The front dot runs a touch brighter than the rears, which helps your eye snap to the front sight where it belongs.
This set is cut to replace the factory front and rear irons on standard-frame Glocks chambered in 9mm, .40 S&W, .357 SIG, and .45 GAP. That covers the G17, 17L, 19, 22, 23, 24, 25, 31, 32, 33, 34, 35, 37, 38, and 39. The sights themselves are steel with tritium vials sealed against water, dirt, and oil, so they shrug off recoil and rough weather.
Installation is straightforward if you've got the right tools. The rear drifts into the dovetail and the front seats with a Glock front sight tool, and Meprolight recommends cleaning the threads with acetone and using a dab of Loctite 609 on the front screw. If you're doing several Glocks, a proper sight pusher makes the rear a lot easier since it can seat tight. Not comfortable doing it yourself? Any gunsmith can knock this out in a few minutes.
This set fits standard-frame Glocks chambered in 9mm, .40 S&W, .357 SIG, and .45 GAP. That includes popular models like the G17, 19, 22, 23, 34, and 35, along with several others in the lineup. Check that your model is a standard frame rather than a large frame like the G20 or G21, which use a different set.
No. They run on tritium, a self-contained light source that glows on its own without any batteries, switches, or exposure to a flashlight. That means they're always ready in the dark and keep working in any weather or temperature.
Meprolight covers the illumination with a 12-year warranty, which is a common lifespan for tritium sights. Many owners find their Tru-Dots still glowing well beyond that mark. Brightness fades very gradually over the years rather than cutting out all at once.
Yes, if you have a Glock front sight tool for the front screw and a way to drift the rear into the dovetail. Meprolight suggests cleaning the threads with acetone and adding a drop of Loctite 609 on the front. If you'd rather not risk it, any gunsmith can install them quickly.
