David,
I've not owned or examined the Pietta 1860 .44 Repro you mentioned.
Please be advised that most ALL Italian reproduction gun makers are located in the industrial regions of Gardone, Val Trompia (VT).
There are only a few compaies that actually manufacture complete guns. There are literally dozens of small shops that forge, cast polish, assemble, and finish parts for Colt cap 'n ball reproduction ball revolvers and supply the parts to gun makers. Quality can range from so-so to superb in fit, finish, and function. The main advantage of buying a "name brand" gun is that quality is more likely to be consistent from one specimen to the next.
You have to look at the individual piece and judge for yourself how good it is. Points to examine include:
Fit, quality of machining & polish, bluing & case hardening, attention to detail, timing, lockup, etc.
All repros by Italian law, are proof fired to industry standards.
Have fun and best of luck in your new repro revolver.
