Trijicon 600227 Bright & Tough Night Sights Green Tritium White Outline 3-Dot - Glock 20/21/29/30/36/40/41

The Trijicon Bright & Tough Night Sights (model 600227 / GL04) are a three-dot tritium front and rear sight set purpose-built for the large-frame Glock pistol family, including the Glock 20, 21, 29, 30, 36, 40, and 41 (including S and SF variants).

Each lamp is filled with green tritium gas and framed by a white outline ring, producing three self-illuminating dots that stay visible day and night without batteries or a handheld light. This proven Trijicon technology dramatically improves target acquisition in low-light conditions, helping the shooter align the front and rear sight faster than with conventional iron sights.

The sights are housed in a rugged steel frame with a black finish and a precise 0.144" wide front blade. They install directly into the factory dovetails on compatible Glock slides - no gunsmithing required - serving as a direct replacement for the factory iron sights.

Designed for defensive, duty, and concealed-carry applications, the Bright & Tough Night Sights give your large-frame Glock a reliable aiming reference around the clock - from bright daylight to complete darkness.
