It also uses a plastic trigger and safety. All of these parts can be replaced with metal parts with very little effort and additional cost. As far as any other differences I am not sure. I do own 2 92Fs and love them both for their purposes. I believe the military's M9s are original designs and use the older style takedown lever. On newish 92s a button has been added to the other side of the gun so that both have to be manipulated for takedown. Yes the will takedown with a live round in the chamber just like in the movies, but I challenge you to do that while I am pulling the trigger.
