If you take your slide, and slip a casing behind the extractor, is it hard to move the case up or down? It should fit and hold, but be quite easy to slide up or down. I'm betting tight extractor - there are no signs of peening the upper lugs, and no hammering on the legs - one or both would be present in the event of timing issues. The tight extractor carries the case back on to the mag, and the top round, the resulting drag causes the slide to stop.
