One thing that is deceptive I found was the hole at the rear of the extractor chain to remove the back plate is smaller than it appears. I pushed and pushed with no results as my tiny little screwdriver wasn't tiny enough. The hole is kind of half round and it's still very easy, just have to make sure you have the small enough jewelers screwdriver or other means of depressing the extractor chain in.
