Last I heard, Taurus bought (or aquired, whatever) Rossi. They are now being run by and imported by Taurus USA. The Raging Bull, as far as I know, has always been a Taurus product. However, the Winchester model 62A clones that taurus now sells were indeed manufactured by Rossi. The new rossi revolvers (all two of them, or four if you count the two finishes for each) now incorporate the Taurus proprietary locking system which consists of a keyed lock in the hammer. The grips on the new rossi revolvers have been changed from a square butt to a round butt configuration.
My room mate recently purcghased the 357 2" revolver in stainless. The overall quality and workmanship appear to better than that of my three year old Rossi model 518 .22 LR revolver. The cylinder of the newer gun has much less side to side play than the older one. Overall fit and finish on the new revolvers seem to be of similar quality to the Taurus revolvers.
My roomate got his gun for $250 brand new. The comparable Taurus was about $60 bucks more.
The only disappointment is that Rossi no longer makes the model 518 and 515. They were small frame 4" barreled stainless steel revolvers in .22LR and .22WMR respectively. To me, they have a better feel and balance than the S&W model 63 and the Taurus model 94/941. This is probably due to the heavy rib atop the barrel and the heavy underlug.\
Good shooting.
