You'll find that Rossi's run the full range. Some people are going to tell you they are good shooters and some will tel you that they are junk.
Over the years Rossi has had some serious quality control issues. Sometimes you'll get a decent one, other times not. Its a roll of the dice if you don't know what you are looking at.
On a whole they are not nearly as well built as a S&W or Ruger, but depending on its use and what I've said above, they can be just fine.
