Yes, they're great. Light, slim, handy, accurate, reliable. They're based on the famous Winchester 1892 (92)with one of the smoothest and steongest actions made. Some are stiffer out of the box than others. If you've got the former, they're often rectifiable with a lot of dry levering or minor parts honing (see Steve Young below). You might do a search here and placeslike

Rossis have been available in different guises (importers) for 35+ years, starting with Interarms ("Pumas") late 70s-90s, Legacy Sports Int'l (LSI "Pumas") and EMF 90s-2008 (and Navy Arms - 2006), and lately just Rossi itself, now under Taurus/Braztech ownership. LSI distributorship brought with it (permanently) an ambiguous safety that's unfortunate (EMF heldout til '06), but rectifiable if bothers with a plug from 92 guru Steve Young (aka Nate Kiowa Jones -
www.stevesgunz.com), who not only fixes, tunes and advises, but sells a $60 DIY DVD and kit for home-grown tune ups.
Some of the above "eras", and depending on the importer, saw periods of better wood, or imoroved sights (EMF) etc. It's been reported that 2000 meant retooling and subsequent guns supposedly were smoother out of the box. This seems, generally, to be true, but
most of my early models (Interarms) have been fine...so it still seems to sometimes to be a matter of individual guns' "personalities."
Like their forebearer Winchesters, Rossis--special forward-mount scout scoped guns aside--aren't set up optimally for traditional scopes. Since most of the Rossis out there are 16" to 20" carbines or short rifles, I find scoping these somewhat antithetical to the idea of a handy trail carbine anyway. If optics are critical for you, Marlin would be a better choice and are fine guns too.
Some Rossis handle shorter .38s out of the.357s better than others. This is another area that can helped by Mr. Young's tutorial.
