The Taurus M85 is a nice gun, but it has a grip that leaves your pinky finger dangling in mid-air. My wife did not feel she had control of the weapon.
She likes to carry a Colt SF-VI (that's a roman numeral six). Six shot .38Special. It has rubber grips and enough weight to it that it is very comfortable to shoot.
I have a Smith Model 60 Lady Smith .357 that I prefer. Smooth wood grips, five shot, smaller than the Colt and very easy to conceal. Not as much fun to shoot, but it is very handy.
I'd skip the ported barrel. It will change the recoil of the gun so that rather than the nose flipping up, the gun will push back into her hand. This may be more controllable, but it is not more comfortable. Puts more stress on the wrist and elbow.
You are going to take her shopping and let her decide for herself, right?
