The Pistola Campo-Giro de 9mm Modelo 1912, unofficially called the Campo-Giro, was the official side arm of the Spanish Army from 1912 until it was replaced by the Astra Model 400 in 1921. It was named the Campo-Giro for its designer Colonel Don Venancio Lopez de Ceballos y Aguirre, Count of Campo-Giro.
