Hello, I was given the .38 from a friend..the gun was her dad's service revolver..he is really sick and in a nursing home and she didnt want the gun in her house anymore. Not sure if gun is registered in PA but we are all Pa residents. what do i have to do to make sure transfer is legal?..not really into going through the hassel of a FFL dealer and all that. is it simple as filling out a BOS?
