Now I received my 19-3, had looked better in the dealer pic´s. There are some scratches on the side plate from a „Bubba-Job" ( they tried to pry the side plate loose with a screwdriver or so)
There was also an issue with the cylinder stop, every couple of trigger pulls the hammer won`t cock.
At this occasion I replaced the rebound-,cylinder and mainspring. Problem solved, now the action is smooth as butter.
