Not sure if this video is real or not but if it is then this guy needs to be fired! I'm assuming from watching the video below, this guy is holding some kind of training class on guns. Well he's teaching people about the gun and then he pulls the hammer back and BOOM!! Luckily nobody was hurt or anything but man! Don't think anyone will be signing up for his class ever again!
The best part of the video is at the end when the guy in the blue shirt asks him a question after he fires the gun.
