The grappling pistol is a fictional grappling device developed by the British Secret Intelligence Service's (SIS/MI6) research and development division, Q-Branch. Such a device first appeared in EON Productions' 1964 James Bond film Goldfinger, with variants featured in 1971's Diamonds Are Forever and 1995's GoldenEye (equipped with a miniature laser cutter).
While infiltrating the Arkangel Chemical Weapons Facility by bungee jumping from the top of the facility's dam, James Bond utilizes a grappling pistol to grapple onto a section at the base of the dam and pull him towards an entrance point. He then used the pistol's built-in laser to cut open a panel preventing access to the chemical warfare facility's ventilation system.
Appearing in the 2004 video-game Everything or Nothing, named the Rappel Gun, the device is a grappling-hook pistol developed by Q-Branch. It fires a grappling hook to a secure holding point at the top of an accessible ledge, allowing its user to fasten a cable to their belt and climb or descend with ease.
