If the trigger feels “crunchy,” than I would have it smoothed out for sure, but if it’s just heavy, I’d leave it alone. In a stressed situation with jacked adrenaline, she won’t have any trouble pulling the trigger until the gun is empty, whereas a too-light trigger could lead to an accidental discharge while drawing the weapon. Especially if she carries it in a purse or deeply concealed holster.
Just my opinion, but I’ve had revolvers for longer than anything else and learning to draw while simultaneously cocking the hammer both increases safe control of the gun and lightens the trigger pull so that first shot goes where it’s supposed to.
