The pin that is behind the extractor - its not flat on the end (it has a slight bevel). Does it matter which way this bevel is facing in relation to the extractor? (ie, should it be facing out, or towards the frame, etc).... I had some more issues at the range today - virtually every casing failed to extract. When I got home, I disassembled the extractor, cleaned it again, and reassembled it. Not sure if the extractor pin needs to be installed in a specific fashion.
