I have a Rossi 451. If you had asked about Rossis earlier when I had only shot .38spl out of it I would have praised my gun and suggested one for you. However, about a week ago, I shot a bunch of .357mag out of it and had the cylinder bind on nearly every shot. From my internet research, binding issues are common with Rossi. On the plus side, they sound like they are a relatively easy fix after which it will be a fine gun for a great price, but the odds that you'll need a fix are a bit higher than I like. So, mine is a mixed review, but you can end up with a good gun at a great price (just be aware that you might need to have a little work done).
Which model are you considering?
Oh, one more consideration, if the older woman you are shopping for has any strength or arthritis issues in her hand, you might want to consider Taurus or S&W. The trigger on mine is much heavier than the trigger on any Taurus or S&W I've ever shot.
