I bought this from an NYPD Officer. Its interesting in that it has the full hammer. The guy I bought it from was not a gun guy, so, I don't think he had it converted back over. He said at "Gun Day" at the academy, they had the Smiths and the Rugers. He said he picked the biggest one possible as he is a big guy. He originally had a massive set of Pachmyers on it, but had the brand new factory grips to go with it. It letters as an NYPD gun. (I know its a Ruger, but, the title says NYPD Guns Generally!)

From my wandering around on the Ruger Forum, the NYPD Rugers are the rarest of them as the Smiths were considerably more popular. And, all the confirmed NYPD Rugers have a start stamp in the crane. The belief is they were stamped that way by the firearms unit when they passed initial inspection.
