TruGlo TG231G2 Tritium Handgun Night Sight Set - Green Tritium/Black Nitride Fortress Frame - Glock

Upgrade your Glock's low-light capability with the TruGlo TG231G2 tritium night sight set. Built around a rugged steel Fortress Frame finished in Black Nitride, this set delivers the durability and corrosion resistance shooters expect from a duty-grade sight upgrade. The front and rear inserts carry green tritium lamps that produce a constant, battery-free glow, transitioning cleanly from standard white-dot daylight performance to glowing green dots in the dark.

The sight picture pairs a square-profile front post with a U-notch rear for intuitive alignment under stress, and installation is straightforward - the front drops into the factory post hole while the rear seats in the slide dovetail. The TG231G2 fits most factory-slide Glock pistols chambered in .45 ACP and 10mm Auto (except MOS variants). Whether you carry, compete, or keep a Glock for home defense, this set gives you a fast, confident sight picture the moment the lights go down.
