I decided to field strip my Springfield for the first time this morning. I got it apart with some effort - the spring on that thing is heavy and the gun is well oiled. When I tried to put it back together I got everything lined up and when I tried to push the slide pin back in place it went mostly in and then stopped about an 1/8" from flush. I tried to readjust the slide but it moved forward only slightly and after that I couldn't move the slide at all. I tired to pull the pin out, but the slide is forward enough that it's blocking the slide release. It's really stuck - I cannot move the slide at all.

Not sure what to do at this point that doesn't involve possibly damaging the finish or the gun. Anyone have any ideas?
