I did a search and found a short thread about this subject that didn't really answer my questions and have seen others in the past few years on other discussion boards. Also I put this here because I want to get some gunsmith's opinions about it.
I have two Pietta .36 Navy Colt cap 'n' ball wheelguns, s/n E51607 and 491940. Steel frames, rounded trigger guards, never been loaded. I've had the first some years now and got the second last year. At the moment I plan to send them to Steve's Gunz for action jobs with the intention of eventually fitting Kirst cartridge converters into them, but that may change depending on the replies I get here.
Lately I've been wondering if the quality of the steel and workmanship is worth the money I'd spend to do the modifications. I've seen discussions where the majority of opinions held the Uberti products to be superior to the Piettas, and certainly that is reflected in the prices if they're an indication of overall quality and workmanship. I've also seen assertions that the Piettas are or at least can be as good, or nearly so, as the Ubertis. Much seems to depend on when the revolvers were purchased. In short, I'm not a lot more enlightened now than when I started researching.
So, gunsmiths and shooters of both marks, please let me know what you think of this. Should I go ahead with my plans for the Piettas? Should I get Ubertis for the slick-up and conversion route instead? If I do that, I'll sell the newer gun and keep the older one for naval reenacting (which means keeping it all shiny and never loading or firing it), but I'll send it to Steve's Gunz anyway because I tried my hand at being a gunsmith with it and now it's in need of a
real 'smith to make it work right

All opinions, help, advice, ideas, etc. will be very much appreciated.
