I took apart my Winchester 1400 auto to clean and now I can't get it back together. The charging handle seems like it is not installed properly. It's holding the firing pin against the back of the bolt. The firing pin should have some play with the spring where you can push it in and out a bit. The charging handle plate is pinching the firing pin tight against the bolt. I don't know what I did to screw it up like that. I thought I was putting it back together the same way it came apart. Anyone familiar with this gun?
