A buddy of mine brought me his Glock 19 (1980s LEO issued) with the brass from a round that broke the extractor. I've ordered the extractor and it should be an easy fix for the Glock, but I am curious as to exactly what caused this damage. My guess is either a double charged hand load or it was way over crimped. Notice the flared brass at the back of the case. That took some serious pressure.
