The AmeriGlo GL-822 Trooper Night Sights are a premium three-dot tritium set specifically designed for Glock’s slimline pistols (G42, G43, G43X, and G48). Modeled after sights used in U.S. Federal Government contracts, they are built for quick target acquisition and high durability.
Key Features & Specs
The GL-822 is defined by its high-visibility front sight and glare-reducing rear sight:
| Component | Detail | Specification |
| Front Sight | LumiGreen Outline + Green Tritium | .140" Wide / .180" High |
| Rear Sight | Two-Dot Tritium + Black Serrated Face | .256" High / Square Notch |
| Material | Stainless Steel | Nitride Coating (Corrosion Resistant) |
| Design | 3-Dot Tritium | Self-illuminating (no batteries) |
Critical Fitment Note: MOS Models
If you own a Glock 43X MOS or Glock 48 MOS (the versions with the factory optic cut), there is a specific detail to watch out for:
- The "Overhang" Issue: The dovetail on MOS slides is positioned further back than on standard slides. Older versions of the GL-822 (and many other standard G43 sights) may hang off the rear of an MOS slide.
- The Update: Newer production GL-822 sets have been revised to fit the MOS footprint without overhang. When purchasing, ensure the retailer specifies "MOS Compatible" or check for the most recent packaging.
Performance Profile
- Daytime: The LumiGreen front ring is incredibly bright and eye-catching, acting like a fiber optic but with the permanence of a painted outline. The serrated rear blade eliminates sun glare, forcing your focus onto that front post.
- Low Light/Night: The three green tritium lamps provide a traditional "three-dot" alignment. The lamps typically have a usable life of 10–12 years.
- Durability: Unlike the factory plastic "U-notch" sights that come on most Glocks, these are solid steel and can withstand the rigors of one-handed slide manipulations or hard duty use.
Installation Essentials
If you're planning to install these yourself, you will need:
- 3/16" Hex Thin-Wall Driver: For the Glock front sight screw.
- Sight Pusher Tool: Highly recommended for the rear dovetail to avoid marring the finish (though a nylon drift punch can work in a pinch).
- Threadlocker: Use a tiny drop of Blue Loctite (242) on the front sight screw to prevent it from backing out under recoil
