Description

The AmeriGlo Trooper set brings duty-grade night sight performance to your large-frame Glock. It runs a three-dot layout with a green tritium ProGlo front sight wrapped in a bright orange outline, paired with a serrated square-notch rear that carries a green tritium lamp on each side. That orange front outline is the star of the show in daylight, drawing your eye straight to the front post, while the tritium keeps all three dots glowing when the lights go out. The subdued, serrated rear is designed to promote front sight focus, so your eye naturally lands where it should for faster, more consistent shots.

Where the Trooper Sight Set Earns Its Name

AmeriGlo built the Trooper line off what it learned from its award-winning U.S. Federal Government contract sights, so this is proven geometry rather than a gimmick. The steel construction holds up to years of holster wear and slide cycling, and the serrated rear face gives you a solid edge for one-handed slide manipulation against a belt or holster. Maintenance is about as simple as it gets: a wipe with a cloth keeps them clean, and the tritium does its job without batteries or charging.

Fit and Setup for Your Glock 20/21 MOS

This GL817 set covers a wide range of large-frame Glocks, fitting the Gen 1-4 models in 10mm, .45, and .357, including MOS slide configurations. The front sight measures 0.140" wide by 0.165" tall, and the rear stands 0.276" tall. Installation is straightforward for anyone comfortable with a sight pusher and a front sight tool, and plenty of folks swap them at the kitchen table without a trip to the gunsmith. If you'd rather not tackle it yourself, any competent shop can knock it out in a few minutes.

Bottom line, the Trooper set is a smart pick for home defense, duty carry, or anyone who wants their large-frame Glock to shoot as well in the dark as it does at the range. The green-and-orange combo makes for a sight picture that's quick to pick up and easy to trust.

Frequently Asked Questions

Will the AmeriGlo Trooper set fit my Glock 20/21 MOS?

Yes. The GL817 is made for Gen 1-4 large-frame Glocks in 10mm, .45, and .357, and it's listed as compatible with MOS slide configurations. It also covers other large-frame models including the 29, 30, 31, 32, 36, 40, and 41.

What makes the orange front sight worth it over plain black sights?

The orange ProGlo outline gives you a high-contrast focal point that grabs your eye instantly in daylight, which speeds up front sight acquisition. At night the green tritium lamp takes over so you still get a clear three-dot picture in the dark. It's a day-and-night setup rather than a night-only sight.

How long does the tritium last on these sights?

Tritium glow gradually fades over time and generally stays useful for well past a decade of service. There are no batteries to change since the illumination is self-powered. Once the lamps dim down the road, you'd simply replace the set.

Can I install the Trooper sights myself?

Many owners install them at home with a sight pusher and a front sight tool, and the process is straightforward for anyone comfortable working on their Glock. If you'd rather not, any gunsmith or shop with a sight pusher can handle the swap quickly. Just be sure the front sight is torqued down properly so it stays put.
