SPAS-12 (FarCry 4)

“This Italian semi-automatic shotgun can be fired quickly, but requires the user to be more diligent with their aim than other shotguns.”
— in-game handbook

“This Italian semi-automatic shotgun is one of the few weapons on Rook Island that was imported legitimately. SPAS-12s were used by private security forces hired by the mining corporations that set up shop in the 1980s. When the mining companies fell apart, it was cheaper to abandon these weapons rather than shipping them back overseas.”
