I have a gen 1 Glock 17. It is not ejecting spent shells to the side. It is throwing them right back toward the shooter. This first started happening while preparing my wife for CCP class. After reading some on line, it seemed most times this was operator error in not having a firm grip. I fired a full magazine through while really taking notice of grip. I had the same issue. Any thoughts on what it could be? Any and all help is appreciated.
