Was just teaching my girlfriend to shoot yesterday. Once I got her holding the gun correctly, she was aiming and firing slowly like this. After a few shots, I got her to pull the trigger three time as fast as she could. She hit all 3 shots center mass. I told her that if she ever has to shoot at a person, always fire 2-3 shots and repeat as necessary.
Wrap her left hand around the 3 fingers that are gripping the lower. The left thumb should be facing the target. The right thumb is resting on the indention that is fixed below the slide catch. 👍🏽
