I just picked up a new Springfield Loaded model. The problem is: The last round of the magazine will feed, fire properly, and then it extracts really wimpy. Sometimes this last casing will go UNDER the lips of the magazine and cause a serious malfunction. If I load a single round into the mag and chamber it, when I rack the slide back to take it out the round will either barely eject or it will get caught in the ejection port. I don't think its the extractor because I tried putting more tension on it and the rounds would fly out with authority, but the last round will still hang up. Any suggestions?
