My experience is that Pietta and Uberti today are about equal on fit and finish. Some people say the Uberti is marginally better in fit and finish, and that may have been true comparing the Uberti's with earlier Pietta's. But Pietta has come up a lot in quality and I would put them now in the same quality as Uberti. Although for some inexplicable reason the Uberti's still seem to command a higher price than the Piettas on gunbroker auctions. Trust me, you will hear some people say Uberti's are better while others will argue that Pietta's are just as good. Truth is, they are both good with the Pietta's usually being less expensive because of the past impression that Uberti's are better lingers on.
So although quality fit and finish these days are about the same, there still are some differences between the Uberti and Pietta 1858 Remingtons.
The Pietta 1858 Remy will sometimes have a bit larger grip than the Uberti.
Which is good for larger hands. Although I have 3 Pietta 1858's and my stainless one has a larger grip and grip frame than my other two 1858 Piettas. Go figure.
The Uberti has a slightly longer cylinder than the Pietta. So a Pietta cylinder will fit in an Uberti but shouldn't be used because that creates to much of a barrel to cylinder gap. Likewise the cartridge conversion cylinders for the Pietta will fit into an Uberti, but shouldn't be used for the same excessive barrel to cylinder gap reasons. Bottom line, either one you get you have to use their own particular cylinders in them and also cartridge conversion cylinder made specifically for that brand.
The other differences are that the Uberti dovetails its front sight into the top of the barrel. Uberti also dovetails its loading rammer latch attachment into the bottom of the barrel. In contrast, Pietta silver solders both its front sight into a hole in the top of the barrel and also silver solders its loading rammer latch into a hole on the bottom of the barrel.
Here's a comparison between the 1858 Pietta that does not dovetail the front sight and loading lever catch stud under the barrel, vs the 1858 Uberti dovetailed ones. Uberti on the left and Pietta on the right.
Earlier Uberti 1858 Remy's back in the 70's were not dovetailed. But today they are while Pietta's are not. Here's an interesting article from the firing line that covers some of this from back in Aug 2010....

I will say that I believe the sideways tapped in dovetailed front sight and dovetailed loading rammer attachment of the Uberti are more secure than the silver soldered on ones of the Pietta's and earlier production Uberti's.
That is a plus for recent and current production Uberti 1858 Remys in my opinion. Although I don't own an Uberti anything at this time but do own four Pietta's (3 1858 Pietta Remys & one 1860 Pietta) and like them very much.
Again, they are both good quality 1858 Remington reproductions.
Hope this helped you.
