I can tell you that back in the late '80's when I was stationed in Corpus Christi at the armory, we had racks full of them, and most were in perfect, untouched condition. They were for the Seabee's and the MIUWU units, which were reservist. Once a year they came down to take people out to the range to shoot, and we always just took the same dozen or so guns from the top of the rack, and never touched the other ones. Then when the M9 came out, they were all returned to Crane.
