Meprolight USA 102243101 Tru-Dot Sight Set Green Tritium Front & Rear, Compatible w/Glock 17/19/22/23/24/25/28/31/32/33/34/35/37/38/39

When the sun goes down or you're moving through low-light spaces, standard handgun sights become nearly useless. The Meprolight Tru-Dot Sight Set delivers a green tritium front and rear sight combination purpose-built for shooters who need reliable sight acquisition when ambient light fails. Compatible with Glock 17, 19, 22, 23, 24, 25, 28, 31, 32, 33, 34, 35, 37, 38, and 39 models, this Glock sight set replaces your factory irons with self-illuminating optics that work without batteries, switches, or external power sources.

Tritium technology has earned trust across NATO forces, U.S. military units, and Israeli Defense Forces for decades—not because of marketing hype, but because it works when conditions demand it. Each blade in this Glock tritium sight set contains its own self-powered gas light source, creating a consistent three-dot sight picture (green front, green rear) without the maintenance burden of electronic sights. Whether you're a defensive-minded shooter, law enforcement professional, or hunter who's serious about low-light capability, these sights stay functional through weather, gun solvents, oils, and the years between now and the end of the warranty period.

Installation on most Glock models involves pinning the front sight over the existing blade; the rear sight replaces the factory unit entirely. The green-on-green dot arrangement prioritizes front-sight focus and delivers the contrast necessary for fast, accurate target acquisition in dim conditions. Unlike battery-dependent or electronic sight systems, there's nothing to charge, no LED to fail, and no complicated operation when seconds matter.

Frequently Asked Questions

Will these Glock tritium sights work in complete darkness?

Yes. Tritium sights produce their own light through radioactive gas sealed inside each blade. They work in darkness, dim indoor spaces, heavy rain, and any condition where ambient light is too low for standard sights to function.

Do I need batteries or electricity to use these sights?

No. Tritium sights are completely self-powered. There are no switches, no batteries to replace, and no electronics to maintain or fail. They remain illuminated continuously for the life of the tritium charge.

What Glock models are compatible with this sight set?

This set is compatible with Glock 17, 19, 22, 23, 24, 25, 28, 31, 32, 33, 34, 35, 37, 38, and 39. The front sight pins over the existing blade, and the rear sight replaces the factory rear unit.

How do these sights perform in wet conditions or around gun solvents?

Tritium sights are unaffected by weather, gun oils, and solvents. The tritium gas is sealed inside the blade, so moisture, cleaning products, and environmental exposure won't degrade performance.
