As near as I can figure, the round didn’t fully seat and allow the chamber to close BUT the gun fired anyway. Much of the gas blew out through the magazine exploding it into pieces and sending unfired rounds everywhere. It scared the **** out of me. I am an army vet and have never seen anything like this. I’m taking it back to dealer tomorrow and expect he will be helpful, but ***....I don't feel comfortable with another S&W. Will probably just get my money back. Is this a problem with this model or did I just get the one in a million?
