I feel your frustration. I read here very recently that no one has heard a thing from Rossi on this matter. The matter has been taken under advisement and under review, while they are fully apprised of the situation, please stand by for future updates.
Problem I see with selling it is, that you have registered it with Rossi. And while manufacturing problem is that of Rossi, you have acknowledged your pistol as being defective. Therefore if you sold it with non disclosure of the recall the liability could fall upon you or at least in part upon you. This shows that while Rossi does not have a fix for the problem they manufactured and sold, they do have a legal dept. that knows how to pass the buck of liability it would seem.
