Our group has a bunch of FAIR (Cortona) O/U's and they are pretty darn nice guns. No experience with their SxS's, but my 28ga O/U is on a dedicated frame. ST in the 16, 20, and 28 has been fine, but the .410 is finicky about the second shot. Fit and finish seem to be on par with my Beretta 687 SPII and B. Rizzini/Sig guns.
