Have her tighten her grip, she might be limp wristing....she may have shot, and figured out that the firearm didn't fly out of her hand, so she relaxed her grip enough to interfere with proper function.

berettabone has, I believe, left something out.
Not only must her grip be string and tight, but also her arms must be rigid yet not hyperextended.

Counsel her that, contrary to her expectations, recoil won't hurt her as long as she is holding the pistol as tightly as possible, all through the shot and its follow-through. (You might discuss with her the concept of "follow-through," what it means, and how it applies.)
New shooters tend to relax the grip, thinking that it will decrease the shock and pain of recoil. The truth, however, is that a looser grip increases the pain, letting the recoil get a "running start," and also causes jams and mis-feeds. Holding tightly consistently actually eliminates recoil pain.

This may be off topic, but what type of pistol is it?
