A friend of mine had a 9mm. fire directly from his pistol magazine, he told me he was just loading the mags and accidentally he tapped the mag against a table. My brother lives in the same house and he was sleeping in the next room, needles to say, my friend freaked out as the thought of my brother in law possibly had been injured. Fortunately everyone was OK. Now, I always tap my mags before I load the into my pistols, and I had never heard of something like this happening. Has something similar happen to someone in this forum? and how do you call something like this?
