Meprolight Tru-Dot Black Tritium Sight Set - Green Front, Orange Rear

The Meprolight Tru-Dot black tritium sight set brings reliable low-light visibility to your carry gun with a combination green front and orange rear sight design. Built for Glock 42, 43, 43X, and 48X models, these tritium sights use self-illuminating tritium technology so you're not dependent on a flashlight or ambient light to acquire a sight picture in darkness. Whether you're training at night, transitioning between indoor and outdoor ranges, or carrying for personal defense, this Meprolight sight set gives you a consistent aiming reference when it matters most.

Meprolight tritium sights are known for durability and consistent performance across serious shooting disciplines—from competitive shooting to defensive carry. The high-contrast green front paired with an orange rear creates a natural sight picture alignment that many shooters find intuitive and fast to use. The black frame keeps the profile low and matches standard firearm aesthetics while the tritium vials maintain their glow for years without requiring activation or recharging.

Installation uses a post and dovetail mount system designed for drop-in compatibility with Glock subcompact and compact frames. If you run any of the compatible Glock models and want sights that perform when the sun goes down, these Meprolight Tru-Dot tritium sights are a straightforward upgrade that doesn't require gunsmithing or special tools.

Frequently Asked Questions

Will these Meprolight sights fit my Glock 43?

Yes. These Tru-Dot sights are designed for direct installation on Glock 42, 43, 43X, and 48X models using the post and dovetail mount system.

How long do tritium sights stay bright?

Tritium is self-illuminating and does not require batteries or external activation. The vials maintain their glow for years, though brightness gradually decreases over time—typically the sights remain functional for 10+ years depending on use and storage conditions.

What's the difference between the green front and orange rear?

The color contrast helps your eye align the sights quickly. The green front sight is your primary aiming reference, while the orange rear sight frames it, creating a natural sight picture alignment that many shooters find faster and easier to use, especially in dim conditions.

Can I install these myself, or do I need a gunsmith?

The post and dovetail mount system is designed for direct installation on compatible Glock models without special tools or gunsmith work, though you should be comfortable with basic sight installation or consult the manufacturer's instructions.
