The TruGlo Tritium Pro High Set is built for folks running a suppressor or a slide-mounted red dot on a large-frame Glock, giving you a taller sight line that clears muzzle devices and lets your irons show up in the optic window. The front sight uses a bright green tritium vial wrapped in a high-contrast orange Focus Lock ring, so your eye snaps to the front post in a hurry, while the rear carries two matching green tritium dots for that classic three-dot picture. Since it runs on tritium, there are no batteries to swap and nothing to charge under a flashlight. It just glows on its own when the lights drop.
These sights are machined from steel and finished with TruGlo's Fortress nitride coating, which shrugs off oils, solvents, and even ultrasonic cleaning without fading. The rear features a fast U-notch that makes lining up the front dot quick and intuitive, plus an angled front edge you can hook on a belt or holster mouth to rack the slide one-handed in a pinch. The whole package keeps a snag-resistant profile that plays nice with standard holsters.
This TG231G2C set is cut for large-frame Glocks, covering the 20, 21, 25, 29, 30, 31, 32, 37, 40, and 41. It does not fit M.O.S. models. The high-set height is popular with red dot users because it lands right around a lower 1/3 co-witness with many common optics, giving you a solid backup sight picture if the dot ever goes dark. TruGlo assembles these in the U.S.A. using quality Swiss tritium for maximum brightness, and backs them with a 12-year limited warranty.
If you want night sights that pull double duty as usable irons behind a red dot or over a can, this is a smart, no-fuss pick that won't have you fiddling with batteries down the road.
This high set fits large-frame Glocks including the 20, 21, 25, 29, 30, 31, 32, 37, 40, and 41. It is not designed for M.O.S. models, so check your slide cut before ordering. If you run a standard 9mm or .40 frame like a 17 or 19, you'll want the matching TG231G1C set instead.
Yes, the taller high-set height is a common choice for red dot users and generally lands around a lower 1/3 co-witness with many popular optics. That gives you a usable backup sight picture if your dot ever loses power. Co-witness can vary slightly depending on the specific optic and mounting height, so it's worth confirming with your setup.
No batteries and no charging required. Tritium glows on its own through a self-powered reaction, so the dots light up in the dark without you doing anything. Over many years the glow gradually fades, which is normal for all tritium sights.
That's the Focus Lock ring, and it's there to grab your eye and draw your focus to the front sight faster in daylight. Paired with the green tritium dot for low light, you get quick target acquisition around the clock. Front-sight focus is exactly what you want for accurate defensive shooting.
