Easy fix.

Balance a dime on the front sight. Dry fire the weapon and the dime should not fall off. You'd be surprised at how many people actually anticipate and break their wrist. Just make sure she pulls the trigger slowly, it should surprise her when the weapon goes off. She shouldn't pull the trigger back sharply.

Once she gets that down pat make sure she knows to do the same thing wile firing. After a while it will become muscle memory and she will get faster/smoother at pulling the trigger without breaking her wrist.

By the way people do the same thing with cameras. Watch them, they stab the shutter release which of course causes the camera to move thus creating blurred images. They should push it slowly. This is the reason many professional portrait photographers use cabless to press their shutter release. On older cameras they would also lock the mirror up just so it would not create motion by flipping up an down.
