Bolt gun

A Bolt Gun was a powerful handheld firearm. It is assumed that it was created by Torchwood, since both of its appearances where in a Torchwood base.

History

In 42nd century, the gun was still around and was used as a emergency gun. Zachary Cross Flane used it when Krop Tor was being attacked by the Ood. Rose Tyler used the same gun when leaving Krop Tor. She used it to smash the glass of a spaceship, causing a possessed Toby Zed to be sucked out. (DW: The Satan Pit)
