You can be assured that, regardless of brand, you may need to "fine" tune a 1911 (especially from the under $1K offerings). I have a Kimber Pro Tac II SE (internal extractor) and it has continued to work, right out of the box, from the beginning. Others, however, have had trouble from shot 1. That goes for Para Ord, Springfield, etc., etc.. I wouldn't worry too much about the Springfield G.I.. If the price is right, and it fits your needs, then go for it.
