The TruGlo Tritium Night Sight Set (brand part number TG231G1) keeps a Glock sighted in even when the lights go out, transitioning from a standard white-dot sight picture in daylight to glowing green dots front and rear after dark. TruGlo builds the set on a black nitride Fortress frame for corrosion resistance and long-term durability, using a front post and rear dovetail mounting style for a secure, drift-adjustable fit. Because tritium is self-illuminating, there are no batteries to replace and nothing to charge. It’s compatible with Glock models chambered in 9mm Luger and .40 S&W.
