Meprolight Tru-Dot Tritium Night Sight Set for Glock 20, 21, 29, 30, 36 - Steel Blue/Green Front

When the sun sets or clouds roll in, your standard handgun sights become nearly useless. That's where the Meprolight Tru-Dot Tritium Night Sight Set for Glock 20, 21, 29, 30, 36 makes the difference. These self-illuminating night sights use tritium gas light sources to give you a usable sight picture in darkness or low-light conditions without batteries, switches, or buttons to worry about. The steel blue front sight contrasts with the green rear, creating a clean 3-dot sight alignment whether you're shooting in daylight or deep shadow.

Tritium night sights are the choice of professional shooters—military units, law enforcement agencies, and armed citizens who need to perform under all conditions. Unlike electronic or battery-powered optics, tritium sights are completely passive and unaffected by weather, gun oils, solvents, or the passage of time (tritium has a 12-year half-life, more than enough for the operational life of most handguns). You don't need to remember to charge them or replace batteries; they work the moment you draw. The front sight's green hue stands out against the green rear blade, making target acquisition intuitive even when your eyes are adjusting to darkness or stress is running high.

Installation on your Glock 20, 21, 29, 30, or 36 is straightforward—the sights replace your factory originals with standard Glock dovetail fitment. Whether you carry for duty, home defense, or sport shooting, night sights turn low-light scenarios from a liability into a non-issue. The Meprolight Tru-Dot is combat-proven and built to last.

Frequently Asked Questions

Will tritium night sights work in complete darkness?

Yes. Tritium is self-illuminating and does not rely on light bounce-back or ambient light. The sights will be visible in total darkness, though they produce a dim glow compared to daylight sight picture brightness. They're most effective in low-light and night conditions where your eyes have time to adjust.

How long do Meprolight Tru-Dot sights last?

Tritium has a 12-year half-life, meaning the sights remain functional well beyond the operational life of most handguns. Meprolight backs the Tru-Dot with a 12-year manufacturer warranty to the original purchaser.

Do these sights fit my Glock model?

This set is designed specifically for Glock 20, 21, 29, 30, and 36 models and uses standard Glock dovetail mounting. Check that your Glock matches one of these models before purchasing.
