The TruGlo TFO Fiber-Optic/Tritium Sight Set (brand part number TG-TG131GT1B) equips a Glock 42, 43, 43X, or 48 (except MOS models) with TruGlo’s TFO technology, pairing a green fiber-optic front with a yellow fiber-optic rear, both backed by tritium night sights underneath for a consistently bright sight picture day or night. The fiber optics gather ambient light for a bright, easy-to-distinguish two-color reference in daylight, while the tritium vials take over once the light fades. TruGlo builds the housing low-profile and snag-resistant so it fits standard holsters without catching on the draw, and the fiber measures 0.060 inches in diameter for a crisp, visible dot.
