“Or beat the snot out of the old guy with the barrel of the weapon. “
He had to struggle for a while just to get the gun away. Best not to let the gun back in reach of the old guy.
Notice that their is something attached to the Barrel making it easier to be grasped in a fight.
Either that old guy is very strong, or hopped up on adrenaline or drugs, or the young hero is physically weak. And mark my words, he IS an American Hero.
