In the mid 90's it was one of the few back-up guns authorized by them. I also believe that it was allowed in a double action only configuration. How do I know........ I once bought a Model 60-7 from a Rookie CHP LEO and when the gun arrived it was DAO!! When I called him to say that it was not advertised as DAO he did not even know that there was a model that offered both DA and SA. He was very apologetic, and paid for he return freight and gave me back all my money. Told me he was simply not a "gun-guy" and this is what the Academy told him he could use as a BUG.
