Hammer less snub nose 327 mag., get her comfortable with the light 32 loads and put the mags in for Self defense. If something happens she will be so amped up the last thing on her mind will be noise and recoil. Get her a 22 mag to shoot and enjoy at the range. Give her some trigger time with the PD gun to be familiar. Men need to step up to the plate and explain that personal defense is not a comfortable subject nor should it be addressed so. Training with a 22 mag is still giving her the basic good shooting tactics that will show up in a situation gone bad. Taking on a carry gun could very well get you killed. It has to be a way of life. For example keeping her hand on the weapon in a dimly lite parking lot walking to her car. Most people don't realize there is more to strapping on a hog leg and calling it covered. I think you mentioned some self defense classes. That would be the best thing you could give her. I will say it again a 22 strike to the shoulder is going to pis a druged out fool off.
