I bought one of those back in the mid '70s
We were young and both very junior in the service. We moved to an area between our two bases and the police response time there, northern Florida between Gulf Breeze and Ft Walton Beach, could be long if the police were on the mainland instead of Highway 90. I wanted better and the guy tried to sell me something he said was french and "all the Navy pilots took them to Viet Nam." Just couldn't afford better at the time.
When I got orders to overseas in '78 I sold it to a co-worker who was close to retirement and intended to keep it on his boat. He went fishing out in the gulf and sometimes hooked into a shark that he didn't want to bring on board still alive! Then just after we got back to the states President Reagan and the others were shot using the same model...
Back then Tandy had a holster kit that fit the gun. I made one and it turned out really well, but definately NOT for concealment. It wasn't held tight to the body and had a huge retaining strap for such a small gun. I bought a Tandy leather craft kit and made something for my wife. When her supervisor saw it and learned that I'd made it he asked, "When was he in prison?" (I wasn't, but did take just about every shop class in jr high and high school.)
