The TruGlo TFO Sight Set (brand part number TG131NT4) brings TruGlo’s tritium and fiber-optic combination to 1911 Officer and Commander-length pistols. Both the square front sight and U-notch rear sight use green fiber-optic elements layered with Swiss tritium, giving a bright, consistent sight picture in daylight and total darkness alike. TruGlo assembles the set in the USA, and the low-profile, snag-resistant housing is sized to clear standard holsters without a gunsmith reprofiling the slide. It fits 1911 Officer-length (3 inch) and Commander-length (4.25 inch) frames chambered in 9mm or .40 S&W, including slides cut to the widely used Novak LoMount pattern.
