I nearly bought one today at a local gun show. It was marked NY-1 on the frame under the crane. It also had numbers on the side plate, which I assume must be the armorer's S/N. It has a "factory bobbed" hammer, and according to the seller "a short stroke" action, or words to that effect. He showed me that the hammer did not travel to the rear as far as other S&W actions.

Is there something really special about these 64's other than to a NYPD officer for nostalgia purposes? Something in the way they shoot? Thanks for any enlightment. The show is still on tomorrow, and I could return to see if the many old retired NY officers in the area left it on the table.
