Berille 87 Target

"This? It's a peashooter. But it rarely misfires, doesn't need much maintenance and puts those peas at some pretty fast muzzle speed."

- Dusty Smith, travelling merchant, showing .22 LR handguns

Background
The Fabbrica d'Armi Pablo Berille was one of the least affected by the zombie apocalypse, but had to relocate their entire manufacturing process to U.S.A. bases. Fortunately, most of them were located next to Arizona, and thus, one of the most concentrated survivor areas with larger settlements were really close to receiving Berille pistols.

One of them is called the Berille 87 Target. A large but lightweight pistol, the model uses .22 LR rounds, and pre-apocalypse was widely used by sport shooters as a very accurate target firearm (hence it's name). After the zombies came, those became nothing more than pistols that shoot .22 LR at a surprising efficiency, but with a hard trigger finger.
