Greetings, I'm brand new here. I'm hoping to get as much information as I can about my Smith & Wesson .38 special revolver. It is a 5 shot and the cylinder swings out. The serial number BDV8437 is marked underneath the butt of the hand grip. It has a 2" (or slightly less) barrel. I was told that it was a Police Special, but I don't know what that means and am not sure it that is true. Any help would be appreciated. Thank you, John.
