Trijicon Bright & Tough Night Sight Set for Glock Models 20, 21, 29, 30, and 41 GL04 600227

Large-frame Glock pistols carry serious calibers for serious purposes — and the sights on them deserve to match that standard. The Trijicon Bright and Tough Glock 20 Night Sights GL04 600227 is a self-luminous tritium night-sight solution for the large-frame Glock family, giving owners of these capable platforms the low-light sight performance that the pistols themselves deliver when conditions demand it.

The Trijicon GL04 fits Glock models 20, 21, 29, 30, and 41, including S and SF variants - covering the primary large-frame Glock configurations across 10mm Auto, 45 ACP, and other calibers that these models are chambered in. The Tactical Iron Sights GL04 is purpose-built for these specific models, ensuring correct dovetail installation and proper three-dot alignment on compatible large-frame platforms without any fitment complications.

The Trijicon Bright and Tough GL04 600227 three-dot tritium system provides self-luminous illumination in complete darkness and low-light conditions, without requiring batteries, switches, or electronics. The tritium-phosphor lamps glow continuously through passive tritium decay - always on, always ready, and always providing the clear three-dot sight picture that accurate defensive and hunting shooting in darkness demands. The Bright and Tough series is the first choice of major handgun manufacturers and standard issue with law enforcement agencies at every level. White rings around all three tritium dots maintain excellent daylight visibility.

The Pistol Sight GL04 metal body housing and silicone rubber cushioning are built to handle the recoil that large-frame Glock pistols in powerful calibers produce - significantly more than standard compact configurations. Each lamp is capped with a sapphire jewel to ensure even light distribution and protect against solvent exposure. Aluminum cylinders provide structural protection through years of hard use and regular training.
