Bolt gun

A Bolt Gun was a powerful handheld firearm. It may have been created by Torchwood; its two appearances were in Torchwood bases (the Torchwood Three hub and Sanctuary Base 6).

History
In 2008, Jack Harkness and Toshiko Sato tried to fix one of the bolt guns. (TW: Random Shoes)

In the 42nd century, the gun was still around and was used for emergencies. Zachary Cross Flane used it when Sanctuary Base 6 on Krop Tor was attacked by the Ood. While leaving Krop Tor in a spacecraft, Rose Tyler used the same gun to shoot out the vessel's window, causing a possessed Toby Zed to be blown out into space. (DW: The Satan Pit)
