It's pretty much a given that savvy police officers often carry a second handgun to back up their primary service auto. I believe that the second gun needs to be very similar to the primary in its handling and operation. In my day, this requirement was most commonly manifested with a Model 19 (or 15) in the holster with a 2-inch Model 36 (or 42) in hiding. Under stress, the similar loading, handling and firing was very comforting. But now that the police service revolver is pursuing the Dodo bird, this practice seems to be falling into disuse. It doesn't need to. In fact, there is more reason than ever to pair up the service handgun with a hideout pistol of the same make and/or similar handling.
