I was reading this thread about catching the live round when unloading by covering the ejection port over on FT&T:

In the thread the OP talks about watching another shooter whose pistol's ejector detonated the live round he was ejecting and remembered I had video of this very same thing happening to me. I was shooting a state USPSA match down in KY a couple years ago and on the third stage I shot, my gun jammed after the 2nd round. Slide was locked up pretty bad. I could not clear it conventionally, so I grabbed the front part of the slide in front of the ejection port with my left hand and used my right to smack the backstrap to see if that would clear it. It did, but I got more than I bargained for. The unfired round came back at a funky angle and the ejector hit the primer, detonating said round. It blew the magazine outta the pistol and sent a piece of the jacket into my finger. After I cleared the pistol and holstered, we were able to find the casing on the ground at my feet. The primer had an ejector mark on it that matched the ejector on my pistol perfectly.
I cut the piece of jacket outta my finger and put a bandaid on it. Later that week, I had to do a little more surgery to get the rest of the jacket out. I'm not sure if it was caused by this or not, but I inspected my pistol (STI 2011 custom job from R&R racing) and found a crack on the top of the slide where the ejection port and breech face meet.
Freakishly, this same thing happened to a buddy of mine while he was unloading a 2011 style open gun. He wasnt so lucky. He got Care Flighted from the range cuz a piece of the jacket knicked his carotid (or jugular, cant remember for sure).
Anyway, here's the vid:
Here's the pic of the casing:
