My question is; with a shell casing sitting on the breach face and engaged with the extractor should the base of the shell casing be sitting flat on the breach face? When viewing the slide with shell casing in place my springfield 1911 GI extractor does not allow the shell casing to sit perfectly flat. Shell casing is about 1/64 off of the breach face on the extractor side. I have read several articles on extractor tension and adjustments, but have not heard any comments on how flat the shell should be sitting when held by extractor. Thanks in advance for the great information!
