They are junk. They will self destruct if fired. This is just s case of the media and certain individuals trying to scare the bejesus out of people and overhyping the facts. I remember the media hyping up “plastic guns” and how they would be invisible to x-ray at airports. The product the media and a certain persuasion of legislators were obsessing about was Glock firearms. Not quiet the scary monster in the dark they were making them out to be.
