The Kolibri is the smallest commercially available centerfire cartridge pistol and was introduced in 1914 by Franz Pfannl. The weapons small size makes it difficult to handle and reload, with the 2.7mm cartridges themselves being fairly underpowered. Due to technology at the time being incapable of applying rifling to the bore of such as small caliber, bullets do not spin when fired, greatly affecting accuracy.
"Designed by an Austrian Watchmaker, the Kolibri is notable for firing the smallest centerfire cartridge ever manufactured."
— In-game description
The Kolibri is a weapon featured in Battlefield 1. It is unlocked for purchase at 150 Warbonds upon obtaining rank 10 with the Scout kit.
The smallest weapon in the game, the Kolibri is more of a novelty toy rather than being an effective sidearm. Due to the small size of the bullets, the weapon has a low damage output against enemies. It also has low accuracy due to the difficulty in its handling. This is showcased when holding the weapon as it is only held with the thumb and forefinger.
Due to its low damage output, the best way to obtain a kill with the sidearm is to only fire at heavily damaged enemies. This can be done in combination with the player's primary and taking note of the enemy players health. Despite this, the Kolibri is, however, capable of killing infantry with one magazine through a series of headshots at close range, each inflicting up to 25 damage.
