I assure you the gun is still perfectly operable. As you all know, when the slide is back after empty, you can pull back while pressing the slide lock and it should release. It was barely moving then catching the tiny corner of the slide lock mechanism.
Just to be clear, I wasn't 'filing' on my gun. It was sandpaper to just smooth it out and round the corner. It barely even did anything to it.
