I have a RIA 1911 that every once in a while I have been having the extractor end up behind the round. In other words it does not end up in that little groove that is on the round. This last time I was at the range I noticed it was only happening on the very last round from the mags. I don't know if it was always the last round the previous times I was at the range. Anyone had this happen before? I've probably only put about 300 rounds through the gun. Perhaps it still needs some breaking in? Pics just for fun.
