My replicas (without exception) always come with
that one screw or nipple that was installed by that air-ratchet wielding fiend who works part time 3rd shift at Pietta (and weekends at Uberti) and practically welds one screw to the frame or cylinder. Your job when disassembling a new revolver is to find
that screw. It will be there somewhere and it will test your equipment and your religion.
