I went and cut the new angles on the sear and test fired it and everything was great. Then I went to bevel the firing pin stop and after I did so the gun will try to fire out of battery, when pulling the trigger it will try to push the slide rearward then fire. While doing this, the trigger is spongy but if i pull the slide back a bit and pull the trigger it will fire crisply. What did I screw up and how can i fix it?
