Just once. At the range. At the firing line, during a competition, in front of fifteen or twenty other competitors. :banghead:
It's a local practical pistol match. About six shooters at a time firing at multiple targets at multiple ranges in a set time. When time's up, you drop your mag, clear the chamber, drop the hammer by dry firing, and holster your pistol. This last course of action became so automatic that I didn't even think about it.
Something went wrong during the stage, don't remember exactly what. FTF, FTE, some malfunction or other. Screwed up clearing said malfunction. Basically screwed up the whole stage.
Still don't know how I did it, but I did the clearing drill at the end, but when I dry-fired, it went BANG!
No damage done, except to my pride. Gun was aimed at the backstop.
What I learned? Don't let things get too "automatic". Pay close attention to what you're doing. Even if you did just have a really crappy stage.
