Unless you enjoy kit guns, I'd skip it and just buy a finished revolver.
IMHO, the few dollars you'd save wouldn't be worth all the extra time and effort. The Uberti kits are barely less expensive than the completed guns IIRC. That being said, if you wanted a "custom" finish like say a browned finish with custom stained grips, you might want to go this way. I think the factory finished ones look plenty nice as is though.
