The TruGlo Tritium Pro Night Sights for a Sig 6/8 height pairing, a #6 front and #8 rear (Truglo part no. TG231S2W) give a defensive pistol a sight picture that works in complete darkness. The set pairs a white-outlined front sight with a FOCUS-LOCK ring and a quick, accurate U-notch rear. Assembled in the USA with Swiss tritium, the sights glow with no batteries and no light exposure. TruGlo builds on its TFX Pro design here, adding Pro-level features to its original tritium night sights.
