Hey Will,
Well there just no doubt that the Ubertis are a little better than all the rest, even some of the Colts(uberti made, put together & finished here by colt) But the Piettas that have been imported in the last couple of years have been down right great! I know there are still a lot of them as well as some ASM guns out there that may have a bug or two but you will run into that with Uberti as well. The nickeled Colt Signature series and the Colt Black Powder Arms that I have owned had a much better finish than the others but these are getting hard to find. I would go with the Ubertis just from a quality stand point but like I said, the Piettas arnt that shabby anymore, I have a few of them that are top notch. The Armi San Marco's has some of the prettiest cch that you'll see(not real cch, done with a chemical) but the over all quality is hit & miss.
Happy shoot'en
