I have not had a Uberti 1873, but I have had other models of olde timey revolvers that they make.
I also have a Pietta.
If I were to buy another...well, I'd buy a Ruger Flattop first.
Second choice would be Uberti.
I won't call Pietta bad or substandard, as they are priced competitively, especially if on sale.
But I do think that you get added value with Uberti.
(and likewise would never ever regret a Ruger - the Lipseys single 10 is wonderful, if not completely in keeping with the 1873)
