One more thought to consider in favor of a revolver.

Women more than men are targeted to be subdued for the purpose of rape, kidnapping, etc.

If the target has someone on top of her and she sticks a gun in his side, it doesn't take much for the pistol slide to be pushed out of battery and the gun unable to fire. Training can also minimize this possibility.

The revolver has no issue with this situation, and with the muzzle jammed hard into the attackers body the gasses propelling the bullet are also directed into the wound channel increasing the damage. A revolver with a shrouded hammer is better able to be fired from inside a purse or pocket with fewer moving parts to snag, and no issues of slide interference.

I would classify this as a secondary consideration. Finding a gun that someone is comfortable with that they like to practice with and carry is primary.
