Hey all- Will the Springfield Custom Shop accept 1911's from other companies? i.e. Kimber? I ran 100 rounds thru my Custom II today; and had one Failure to Extract. I did the "extractor tension test" (putting a round in between the breech face and extractor and shaking the slide up and down), and it did NOT come out. I was thinking about sending it to Springfield for the "Reliability Package". My Custom II has 250 rounds thru it so far. What says everyone?
