Like an idiot, while I was on the phone and cleaning my gun, I did not pay attention to if the slide of my M&P Shield 9mm was level when reassembling.. As a result, the slide engaged the rail on the left side, but not the right. Please see the attached pictures, these should better show my problem than what I can explain... When I reattached the slide, I had no resistance until it was about all the way on. At which point I stopped to see what was wrong. Bottom line, I can not move the slide forward, but it appears (with force) it may move more backward. I just don't want to make the situation any worse than it is.. I know I look stupid as heck, but I surely would appreciate any advice / assistance! How can I remove the slide to properly reassemble?
Things I've tried (but no improvement):
Gently rocking the slide side to side while pushing forward
Doing that ^ while holding the trigger
