"Soft" action parts
I think the comments about "soft" metal action parts were about all the Italian manufacturers, which includes Uberti and Euroarms.
I have 4 Pietta, 3 Uberti and 2 Eurorams revolvers of various ages (made from 1977 to 2001). All get used regularly and are all maintained the same way. I have had no reason to change any action parts on any gun for any reason, including unusual wear. In my experience they are all holding up just fine.
I clean each gun after use the same day, and do a complete teardown/inspection/lubrication about 3 times a year. It takes no more than 15 minutes per gun to do the extra action disassembly, cleaning, inspection, lubrication and reassembly. It is really not very difficult at all. I do own a set of gunsmith's screwdrivers and strongly recommend their use in working on the internal action.
As far as fitting new action parts, I have restored two badly abused 1851 Navys for my brother-in-law (he bought them at auction) and did have to rebuild the actions due to corrosion. Fitting the new parts involved some grinding and polishing and did take a couple of hours - a minor investment and actually quite enjoyable.
As for brand preferences, I have a very, very slight preference for Uberti, but I cannot honestly say why. In buying a new gun my discriminants would be reputation of the retailer for customer service, price, cost, and dollars in that order, with manufacturer coming in a distant fourth. I might spend $5 more for Uberti if that were the only difference, but not $6.
