Meprolight Tru-Dot Black Tritium Sight Set - Green Front & Yellow Rear (102203201)

The Meprolight Tru-Dot Black Tritium Sight Set brings reliable low-light shooting to your carry gun with a proven self-luminous design. This green front and yellow rear tritium sight set is purpose-built for fast target acquisition in dim conditions—from a predawn hunting start to a low-light defensive situation. Meprolight's tritium-filled front and rear sights glow without batteries or activation, giving you sight picture when a flashlight isn't an option or when speed matters most.

These sights are designed around the classic three-dot sight picture: the bright green tritium front sight and yellow tritium rear sight create natural eye alignment for quick follow-up shots. The contrasting colors and tritium fill mean you see your sights fast, whether it's broad daylight or complete darkness. White outlines frame each tritium element, sharpening definition in any lighting condition and serving as a daytime reference when the tritium glow isn't needed.

Meprolight's Tru-Dot line has earned its reputation among competitive shooters and defensive-minded gun owners who demand sights that work when it matters. These are straightforward, combat-proven optics with no batteries to replace, no electronics to fail, and no calibration to second-guess.

Frequently Asked Questions

What firearms does this Meprolight tritium sight set fit?

These sights are designed for Glock 42, 43, 43X, and 48 pistols.

Do tritium sights need batteries or charging?

No. Tritium is self-luminous and requires no batteries, charging, or external activation. The sights glow continuously for years without maintenance.

Why green front and yellow rear instead of all green?

The contrasting colors—green front, yellow rear—create a more distinct visual separation and faster sight alignment than a single-color setup. This configuration is favored for combat and defensive shooting where speed is critical.

What are the white outlines for?

The white outlines frame each tritium element, sharpening sight definition in bright daylight when the tritium glow is less visible. They serve as a daylight aiming reference while the tritium provides the same sight picture in low light.
