Jon Erik Hexum was killed by a "blank" I am not sure if the pistol had an adapter or not.
@verga It did,but even blank adaptors MUST have a hole in them to vent the gasses,and he was so ignorant of firearms that he didn't realize this,and when he put the pistol to his head and pulled the trigger,it was those hot,expanded gasses that blew a hole in his skull and killed him,not a bullet.
A tragic death due to ignorance and carelessness,not a suicide. He was literally joking around in front of friends.
BTW,blank adaptors for prop guns are installed inside the barrel by boring it out,threading it,and screwing the blank adaptor inside the bore,out of sight. as I wrote above,blank adaptors have holes drilled in them to release the gasses. The prime difference between movie prop gun blank adaptors and move blank adaptors is the military ones are temporary,stick outside the bore to make it obvious they are installed,and need no tools to install or remove.
You do NOT want to pull the trigger on a firearm with a blank adaptor installed if it is loaded with actual bullets. If you are lucky,all you will lose will be the use of a hand.
