This weekend was the big Missouri Valley Arms Collectors Association show in Kansas City, MO. At this show I found the Colt 2-page news release and a promotional one-sheet for the Colt Tritium Night Sight. I have added these documents to the Colt Tritium Night Sight page here.
Through an auction on Ebay, I found these two items that document a tritium night sight set that was apparently offered by Colt. The large Installation instructions/training guide and the pocket user guide are both dated 1992.
You can see all of the pages of the installation instructions and training guide and the user guide at this link: https://thecoltar15resource.com/colt-tritium-night-sight/
