First, lean into it. Second, off hand should not be above the strong hand, because that will actually enhance the recoil. Lastly, from the way her tendons are standing out, she looks as if she has the sort of death grip on that pistol that will ruin accuracy. Loosen her up.
My shooting position, which she would probably find better, involves cupping the magazine slightly with the lower ball of the palm, and the left fingers angle upward around the right. Left thumb is on the left.
In her position, the recoil is all on her wrist joints, and nothing is in force to naturally draw her back on target. With a better position, her hands will pull back to where they belong.
