I just retired as a captain at City of Tulsa Security (because there are some things police officers won't do).
The Model 642-2 was my personally owned BUG for the three years I was a captain.
The Model 65-1 was the last duty weapon I carried (against policy requiring me to carry the issued Model 686-6). This gun is marked MPD 55, so I wasn't the first badge toter to carry it. Guess I need to get it lettered.
