The TruGlo Tritium Night Sight Set (brand part number TG231N1) keeps a 1911 Government or Ruger SR1911 sighted in even when the lights go out, transitioning from a standard white-dot sight picture in daylight to glowing green dots after dark. TruGlo assembles the set in the USA using quality Swiss tritium for maximum brightness, and because tritium is self-illuminating, there are no batteries to replace and nothing to charge. Built with a square front post and U-notch rear in a front/rear set, it drops onto a 1911 5-inch Government in .45 ACP or a Ruger SR1911 model with a fixed rear sight, using a Novak LoMount-compatible footprint for fitment purposes only.
