I have a 1957 manufacture BlackHawk revolver in .357 Magnum which has gone through the factory overhaul that replaces the old trigger/hammer parts to add a safety feature. When these were done, and most were done this way, the original parts were returned by Ruger with the updated revolver. Soooooo...I think that there are many sets of the original parts sitting in drawers. Is that the case with these? I would like to put it back to original.
