Anything in a similar weight range is going to be "snappy". If you started her with 38 target loads, she might be all right but if your thinking full bore loads, she may shy from the gun quickly. Worse yet 99.9% of people who try 357 in a sub 15 oz gun are going to HATE it. I doubt your experience will be any different. It's not snappy, it painful. It's unrealistic to think she will be different.
That said, she is smart in wanting a revolver. It will suit her much better to learn on and is simple as a hammer to use under stress.
I would point you towards a S&W K frame in a 2.5-4" barrel to start . That will give you the extra weight to absorb recoil and let her work on her comfort/accuracy skills. It will also give you HUGE options for grips to help control recoil. When the time comes for CCW, she may want something smaller and lighter but then she will have an excuse and the skills to move her down in size. My second choice would be a full steel/stainless J frame S&W . Same size as the J frame/LCR but a full 9 oz heavier. Not a great learnign gun, but acceptable.
You need to understand that like golf clubs you can't get one gun to do everything even remotely well. CCW needs and lthe ideal skills building needs are not closely related in most cases.
