My wife and I were out practicing the other day, when we practice we do so like we are in a match, when I told her to unload and show clear she did the same thing and had a AD, TWICE, she did it once and was so flustered from her mistake she reracked the slide and did the exact same thing, didn't drop the mag. And that is why we practice like it is a competition. Moral of the story is when you get flustered its time to slow down and start thinking.
