I've had three of the Rossis, and still have two -- a .357 and a .45. Both are fgood durable guns, and i'd only advise that you look one over carefully before you buy. Rossi's QC isn't the best, and some lemmons do get to the market.
There a gunsmith who advertises in the SASS newsletter that he does Rossi 92 action work. I don't remember the name, but he might be worth contacting.
My main gripe against both the Marlins and the Winchesters is those darn safeties. Rossi still makes theirs like the original 92s.
