I have a Rossi that I think is a clone of that model. I just picked it up in a trade and haven't even shot it yet. I'll have to give it a good workout and see how it performs for me. This is currently my largest double action revolver--it joins an SP-101 and a Smith 642 in my collection. (I have some single actions that are much larger.)
From what I've gathered so far, it could turn out to be a great gun, notwithstanding the poo-pooing often directed at the Brazilian brands. It fits my hand nicely, shows really good fit and finish, locks up reasonably tight... we shall see what it can do at the range.
What else can you tell us about your real SmiffinWesson? I don't know what comprises a -2, except the obvious and important fact that it's from before the Hilary hole era.
