Bolt gun

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