Rachel handles this subject well. The unfortunate thing is that real guns are used as movie props sometimes because of the cost of blank ammo. The bullet is simply removed and wadding added to hold the charge. In the case of Jon Erik-Hexum he put the gun to his head and pulled the trigger as a joke. He died. With Brandon Lee one of the guns still contained a live bullet. He died. I'm told that Arnold Swarzenegger will not be involved with any movie where real guns are used at all. Smart man. The reality is that Hollywood often tries to save a buck and it can sometimes get people killed. It is the production companies who should be held fully responsible when this sort of accident happens. I suggest to start with that no real guns of any type ever be on a movie set.
