Put the slide stop back in and start over. Lock the slide back. Push the ejector forward and stick something in there so it can't come back up if you have to. Let the slide go forward and now take the slide stop out and take the slide off. I have a p97 which is similar to your gun but I can't look at until saturday to help you more.
