This happened to me at a match this morning and I thought it would be a good reminder for the rest of you.   Thankfully there were no real injuries, but I was spooked.  The round felt stuck in the chamber so I gave it a but more force than usual racking at unload and show clear. It popped free and the slide came back really fast. The round detonating bent my ejector and sprayed some debris into my hand.   I'll be racking the slide with the rear serrations from now on.
