Trijicon Bright & Tough Night Sight Set for Glock 20/21/29/30/36/40/41 - Steel Matte 3-Dot Tritium Green

Trijicon's Bright & Tough night sight set for Glock models gives you a serious advantage when light runs out. This three-dot tritium night sight set fits full-size and compact Glocks (20, 21, 29, 30, 36, 40, and 41), replacing your factory sights with self-luminous aiming points that glow on their own without batteries or external power. Whether you're doing low-light defensive training, hunting in twilight conditions, or running night qualification drills, tritium-equipped sights let you see your sight picture and target relationship when iron sights alone leave you guessing.

The sights use Trijicon's proven tritium lamp technology—tiny vials of radioactive tritium gas sealed inside metal cylinders with protective sapphire windows. Each lamp produces its own light for roughly 12+ years of use, giving you dependable illumination without upkeep. Sapphire crystal windows are polished to deliver a sharp, perfectly round aiming dot in darkness. During the day, white rings inlaid around the sapphire make the sights look like conventional white-dot iron sights, so your sight picture and instincts stay consistent from dawn to dusk. The front sight features a very narrow blade design, appearing more like a plain black blade in daylight for less target obstruction at distance.

These are steel matte sights built tough for hard use—the metal construction and sealed design keep the tritium vials protected from impact, moisture, and environmental abuse. Keep in mind that Glock dovetail sights require special Trijicon installation tools to avoid damage during fitting; this is standard for quality sight replacement on polymer frames, and we recommend having them installed by someone familiar with the procedure.
