That i was being carjacked. I pulled out my gun and pulled the trigger, only to hear a sound similar to a cork being shot out of a champaign bottle. The entire cartridge flew out and bounced off his chest. I picked it up, and saw rifling on the outside of the casing, and there was no primer. Apparently along with punching running and screaming, I have a new worthless defense mechanism to add to my bad dreams.
