If its an Uberti or other with the same size cylinder. The part where cylinder was hitting can be filed down smooth. If its not real bad, a Pietta cylinder fits good. They are longer than most any revolver. And the ratchet part is usually the same.Wow , the cylinder imprinted the recoil shield so far the ratchet was knawing in to the bottom of the well! Great pictures ! Must have had a barrel/cylinder gap approaching .030-.040 judging from the depth of the imprints.
