We went shooting this weekend and my wife had two stoppages with her SR1911. It is around 1000 rounds by now, probably more. Both seemed to be FTF(eed) problems, related to the WWB that she was shooting. Don't know for sure, but it may have been a bad batch- that stuff was diiiiiiiiiiiirty, more so than usual. I snaked the barrel and it was good after that.
