Hello out there. I'm hoping someone can help me. I just bought my first gun (a Glock 17) two days ago and I already got myself into a problem. When I got home I disassembled and cleaned the gun with instructions off of the internet. No problem there, but when I went to reassemble, I made a mistake. Rather than replacing the slide from the front and drawing it backwards, I replaced it from the front and pushed forwards. The slide is now caught on the back rails, not able to go any farther backwards or forwards than shown in the pictures below. I would really appreciate it if anyone has any words of wisdom for a new gun owner. Thanks.
