Trijicon HD Night Sight Set for Glock 20/21/21SF/29/30/36/41 - Steel Matte 3-Dot Tritium Green with Front Dot Outline

The Trijicon HD Night Sight Set for Glock 20/21/21SF/29/30/36/41 brings serious low-light capability to full-size and compact duty weapons. Built for shooters who need fast, reliable sight acquisition in any lighting condition—from bright daylight to pitch black—these steel matte sights combine tritium night glow with photoluminescent paint to keep your front sight visible whenever you need it. The 3-dot green tritium configuration is purpose-built for tactical work, self-defense, and serious range time.

The design reflects genuine operator feedback. The front sight blade runs tall and is ringed in photoluminescent paint to anchor your eye quickly, even in transition lighting where your pupils are still adjusting. The rear sight features a wider U-shaped notch that makes finding your sight picture faster and opens up your field of view. That extra width pays dividends when speed matters. The rear sight's front surface is steeply hooked—a detail that makes one-handed slide operation possible in a pinch, whether you're clearing a malfunction or reloading in an emergency.

These sights are built to last in hard use. The tritium tubes are warranted for 12 years from manufacture, so you're getting genuine longevity, not marketing promises. The matte steel finish resists glare and pairs well with tactical and carry setups. Whether you're running your Glock at the range, in the field, or as a carry gun, Trijicon HD Night Sights give you the tool to shoot well when conditions aren't perfect.

Frequently Asked Questions

Will these sights fit my Glock 20 or 21?

Yes. This set is specifically designed for Glock 20, 21, 21SF, 29, 30, 36, and 41 models. Verify your exact Glock model before ordering.

How do these sights perform in low light compared to standard three-dot sights?

The green tritium tubes glow in darkness without any external power or activation. The photoluminescent paint outline on the front sight absorbs ambient light during the day and transitional periods, making the front sight easier to locate when your eyes are adjusting between bright and dark conditions. Standard steel sights rely entirely on ambient light and disappear in true darkness.

Can I use one hand to rack the slide with these sights?

Yes. The rear sight features a steeply hooked front surface designed to catch on a belt, holster, or gear during one-handed operation—useful for emergency reloads or malfunction clearance if your support side is injured or occupied.

How long do the tritium tubes last?

Trijicon warranties the tritium on this set for 12 years from the date of manufacture. After that period, the glow gradually diminishes over time, but the sights remain fully functional as day sights due to the photoluminescent paint outline.
