If you are talking about racking to load a round, I agree with Smith Shooter. Leaving the slide locked back never worked on my first 9mm Shield. I had no problem racking it to load a round. But, it was very hard to lock back for cleaning without a mag inserted. Sold it. But, now have a 9mm Plus with no issues. Still not easy, but very manageable. Now, while firing I have no issue racking to load a round. Try grasping the slide firmly and try pushing the frame forward more than pulling the slide back. Just release quickly to load round.
