I think you have made a fine choice in the gun. I prefer the 44 mag, and let me tell you having hunting in an area where we were walking on grizzly prints I still felt a little vulnerable. But I think with hard cast bullets she will be fine. However, at no point should she load a hollow point in the gun for woods carry. If she does have to face a bear, or more likely a ****** moose, she is going to want all the penetration she can get.
My 44 mag is a Smith and Wesson 329 PD which is an scandium framed revolver. Not very nice to shoot a bunch at the range, but very nice to carry in the woods. It also helps that I cast and load my own bullets for it, way more tolerable to shoot than with factory ammo.
