I agree you may be limp wristed after a few rounds (does not allow the recoil to fully reload the chamber) or you are interfering with the return of the slide with your hand. Have you ever been bitten by the slide? You would know, as it really hurts.
If your boyfriend can empty several MAGAZINES (they are not clips), then it is likely operator error on your end. Sounds like a better grip and more range time are in order.
