The TruGlo Brite-Site Tritium Night Sight Set (brand part number TG231G1A) keeps a compact-carry 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, 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 sized specifically for the Glock 42, 43, 43X, and 48, excluding MOS-cut models, making it a natural fit for a compact or subcompact carry gun.
