TruGlo TG131GT2Y Brite-Site TFO Night Sight Set - Glock 20/21 High - Black Nitride

Upgrade your Glock's low-light capability with the TruGlo TG131GT2Y Brite-Site TFO night sight set. Built around TruGlo's patented TFO (Tritium Fiber Optic) technology, this set pairs a bright green fiber-optic and tritium front sight with a contrasting yellow fiber-optic and tritium rear sight, giving you an unmistakable aiming reference that transitions seamlessly through every lighting condition - bright daylight, low light, and total darkness - with no batteries required.

The rugged steel frame is finished in a low-glare Black Nitride Fortress coating for long service life and corrosion resistance. This high-profile configuration is engineered for Glock 20/21 pattern pistols and is also compatible with Glock 25, 29, 30, 31, 32, 37, 40, and 41. The taller "High" sight picture stands above standard factory sights, making it a natural fit for use with a compensated or suppressor-height setup or for any shooter who simply prefers a raised sight picture. The front sight measures 1.0" long with a 0.060" fiber diameter. Note: this set is not designed for use on MOS-equipped Glock pistols.

Whether you carry on duty, defend your home, or run serious range time, the TruGlo TFO Brite-Site set delivers fast target acquisition and around-the-clock reliability. Installation should be performed by a qualified gunsmith using a sight pusher tool.
