World's Smallest Pistol - 2.7mm Kolibri
This video from Forgotten Weapons showcases the 2.7mm Kolibri, recognized as the smallest centerfire pistol ever manufactured. Produced between 1910 and 1914, approximately a thousand units were made. The video highlights its intricate mechanical design and provides details on its diminutive caliber, firing a 3-grain projectile at around 650 fps, resulting in a mere 3 ft-lb of muzzle energy. Despite its impracticality, the Kolibri is celebrated as a piece of mechanical art, with the presented example including seven rounds of ammunition.
