Question for 45 Dragoon or anyone else who knows the answer

[Smokin'Joe]

Yes, the arbor is a perfect fit. I followed the Pettifogger Tuning instructions when I bought this Cabela's special for $120 a few years ago. Barrel to cylinder gap is .004". As for the solid face hammer that's my modification.
