The AmeriGlo Trooper set takes the design AmeriGlo built for U.S. Federal Government duty contracts and puts it on your Glock. It runs a three-dot tritium layout that gives you a clean, repeatable sight picture whether you're on a bright range or working in a dim hallway at 2 a.m. The green tritium lamps glow on their own around the clock, so there's no fumbling for a switch or waiting for anything to charge up.
Up front you get a ProGlo blade with green tritium wrapped in a bright LumiGreen outline. That colored ring draws your eye straight to the front sight for fast target acquisition, and the LumiGreen paint soaks up ambient light and keeps glowing for about ten minutes after exposure. It's the kind of front sight you find quick under stress without thinking about it.
The rear is a serrated, subdued square-notch blade with green tritium and a plain black outline. That flat black finish and the serrations cut glare and keep the rear from competing for your attention, which is exactly what you want. Your focus lands on the front dot while the rear frames it cleanly. The rear notch measures 0.165 inches wide, the front blade sits at 0.140 inches wide and 0.165 inches tall, and overall rear height comes in at 0.276 inches.
This GL-820 set covers a big spread of larger-frame and slimline Glocks in 10mm, .45, and .357 SIG, including the 20, 21, 29, 30, 31, 32, 36, 40, and 41 across Gen 1 through 4, and it works with MOS slides too. Both sights are steel with a matte black finish and made in the USA. Installation calls for a sight pusher for the rear and a front sight tool with a dab of thread locker on the screw. If you're not comfortable pressing sights yourself, most gunsmiths will knock this out in a few minutes.
This set is cut for larger-frame and slimline Glocks in 10mm, .45, and .357 SIG, covering the 20, 21, 29, 30, 31, 32, 36, 40, and 41 in Gen 1 through 4. It's also compatible with MOS slides. If you're running one of those models, you're good to go.
Tritium sights use a self-illuminating gas that glows without any batteries or charging, and it typically stays usefully bright for around 10 to 12 years. On top of the tritium, the LumiGreen front outline soaks up ambient light and continues glowing for roughly ten minutes after exposure. Between the two, you get visibility around the clock.
Yes, the rear sight is a press fit and should be installed with a sight pusher rather than a punch and hammer to avoid marring the finish. The front sight secures with a screw from underneath the slide and benefits from a small drop of thread locker. If you don't have the tools or the experience, any gunsmith can install these quickly.
The Trooper rear is a subdued, serrated black square-notch on purpose. Keeping the rear plain and glare-free pushes your focus to the bright front dot, which speeds up sight acquisition when it counts. The serrations also cut reflections in bright light.
