For all the time we shooters spend on the practice range, in classes, and in competition I'm sure we all have loads of stories of wild, scary, funny, or otherwise unusual things we've seen. Let's hear them!
Here's a start:
I shoot USPSA with a police officer who is a pretty good shooter and a nice guy. A few weeks back he decided on a whim to shoot his duty rig, including his duty pistol. He could barely finish each stage due to constant malfunctions. He said it had been a few weeks since he shot the pistol, and clearly in that time his magazine springs (I think he had four mags) all went kaput. It seemed like he was both embarrassed and freaked out that he had been carrying his duty gun for weeks not knowing it didn't work! I would have been freaked out as well.
Another: This was in a class I took. At the end of the first day we were going to be doing dry fire drills in a class room, and the instructor was extremely clear that there was to be no ammunition, at all, in the room. He told us outside the classroom to go put any ammo in our cars and lock it up. Then, one by one we stopped at the door and showed him an empty gun and empty magazines. The rule was, if you leave the room, you go through the whole "check in" process again. So we all got checked in, and the instructor told us that just to be even safer, he was going to frisk us to make sure there were no loose rounds or loaded magazines in anyone's pockets. Everyone consented. Well, about the third guy he frisked turned out to be wearing a bullet proof vest, and he had a .38 snub nose revolver on his ankle - loaded. The instructor "confiscated" the revolver, we finished the lesson for the day, and the idiot who owned the revolver wasn't invited to come back the next day.
