Don’t know why but sometimes this thing is so hard to rack I mean it’s to where I can’t even rack it but Sometimes it isn’t. Has anyone experienced anything like this with any pistol?

Let me ask, is it possible you're not racking the gun the same way every time? I had a lady I taught to shoot have the same problem, I taught her to pull back on the slide while pushing forward with the frame, and she had no problem. But sometimes she would hold the frame steady and pull back on the slide, and it was much more difficult for her.
