The Kolibri single-shot pistol, officially known as the Kolibri Model 1, is an Austro-Hungarian break-action pistol.
The Kolibri single-shot pistol was manufactured by Kolibri from 1914 to 1938, and marketed alongside the more well-known Kolibri self-loading pistol. The pistol and ammunition were designed by Franz Pfannl, an Austrian watchmaker, with financial support from George Grabner.
The pistol uses a break-action system, similar to the Thompson Contender. Due to the small size of the weapon, it lacks any form of rifling, and as such, is very inaccurate. It was also rather difficult to load and shoot the weapon due to its small size. When fired, the cartridge has a normal muzzle velocity of about 200 meters per second (656.2 feet per second), and a pathetic muzzle energy of just 4 joules (0.96 calories).
