I can't recommend that an inexperienced shooter with a small stature get a 44 mag for woods protection. The amount of recoil is very important. But so is having a firearm that is powerful enough to provide some protection when necessary. I believe she will find the 357 mag uncomfortable to shoot. So I recommended the Ruger GP-100 in either a 3" or 4" configuration as the most powerful handgun caliber that is practical.
I think the "Judge" (Taurus or S&W version) would be a poor choice as would an airweight revolver. But I do suggest a revolver over a semi-auto pistol.
