The AmeriGlo Classic Tritium set is the sight upgrade a lot of Glock owners reach for when the factory plastic sights start feeling like a liability in low light. You get a green tritium lamp with a white outline up front and two green tritium lamps with white outlines in the rear, giving you a clean, familiar three-dot picture. The white outlines pull your eye to the dots in daylight, and the tritium keeps glowing on its own once the sun goes down, so there's nothing to charge, switch on, or babysit.
These are cut from domestic bar stock steel, not molded polymer, so they hold up to hard use and repeated holster wear. The lamps use genuine Swiss-made tritium, which is the same self-luminous technology relied on by law enforcement and military users worldwide. The rear notch runs .150 inches wide and the front blade measures .140 inches, a proportion that gives you a good balance of light on either side of the front post for quick, repeatable alignment.
This set is built for the large-frame lineup: Glock 20, 21, 29, 30, 31, 32, 36, 40, and 41 in Gen 1 through Gen 4. It's a great match for 10mm, .45 ACP, and .357 SIG shooters running a full-size or subcompact big-bore Glock. Keep in mind this particular set is not cut for Gen 5 or MOS-specific slides, so double-check your generation before ordering.
Installation is straightforward if you're comfortable working on your slide. Most folks use a Glock front sight tool for the front and a sight pusher for the rear, along with a little blue thread locker to keep things put. If wrenching on your own pistol isn't your thing, any competent gunsmith can knock this out quickly and confirm your zero. Once they're on, you've got a rugged, self-illuminated sight picture ready for the range, everyday carry, or duty.
No, this GL119 set is cut for Gen 1 through Gen 4 large-frame Glocks. Gen 5 slides and MOS-specific cuts use different dimensions, so you'd want the matching AmeriGlo set made for those. Always confirm your generation before installing.
Not at all. Tritium is self-luminous, meaning the lamps glow continuously on their own without any light source, battery, or charging. That's the whole appeal over painted or photoluminescent dots that fade after the lights go out.
Plenty of owners do it at home with a Glock front sight tool for the front and a sight pusher for the rear, plus a dab of blue thread locker. A wooden dowel and a light hammer can work in a pinch, but a proper pusher makes rear alignment easier. If you'd rather not risk marring the slide, a gunsmith can handle it fast.
This set spans the large-frame lineup, which covers 10mm (20, 29, 40), .45 ACP (21, 30, 36, 41), and .357 SIG (31, 32). Whether you're running a full-size, compact, or subcompact big-bore Glock, this set has you covered as long as it's Gen 1-4.
