The Brun Latrige Pistol,
Patented in 1868 but not manufactured until 1890, the Brun Latrige was a French pistol with a very odd design. Firing was done by pulling back on the trigger/trigger guard. Pulling back on the trigger would eject an empty casing, load a new casing, and fire the cartridge. That is why as you can see the pistol has such a long trigger pull. The gun was fed from an internal magazine which held 10 small 6mm rounds. An odd looking pistol, they were underpowered and few were produced.
