Were extractors available from the factory when gun was new, or were all 3200"s (12ga) produced with ejectors? On any of the schematics i've viewed it only shows/labels ejectors. Are the extractor and ejector the same part number? I have a 3200 that the shell occasionally slips through the ejector, so i have ordered new parts by phone, and i requested extractors by error, but wanted the ejectors. Are they the same part?
