Designed by Friederich Pfannl of Austria, the Kolibri and its cartridge, the 2.7 Kolibri, are credited as the smallest centerfire pistol and centerfire cartridge to see production. Produced without sights, with "FP" imprints on both grips and "KOLIBRI" on the right grip panel. Included with the pistol are two scarce 2.7 Kolibri cartridges and a small unmarked metal box sized properly to hold the cartridges.
