bites through gun

Carmichael beat me to it. His round belly had been ripped open. There was blood all over his cheap suit, though his food-stained tie had somehow remained untainted. His face was grave pale and set with the sort of intensity that only a dying man can have. He held a bent and twisted riot gun in his hands and he hurled himself onto the loup-garou's back as though he weren't sixty pounds overweight and long past his agile years. He wedged the riot gun between the loup-garou's jaws, but the beast turned and slammed Carmichael into the wall with a sickening crunch of bone and a gout of blood from the man's mouth.
Murphy slithered out from between the beast's paws on her shoulder blades and buttocks, her cute little cheerleader's face set in a berserker's fury. She jammed the end of her little gun beneath the thing's chin. I saw her hands convulse on the trigger. But instead of a flash of light and a dead loup-garou, there was only the whooping of the alarm and a look of shocked surprise on Murphy's face. The gun had run empty.
"Murphy!" I shouted. "Roll!"
She saw me with the blasting rod and her eyes flew wide. The loup-garou shook its shoulders free of Carmichael's corpse and bit completely through the riot gun, thrashing its head left and right. Murphy scuttled sideways across the tiles and through the hole in the wall the beast had made earlier.
