The semi-automatic Ruby pistol is best known as a French Worl War I sidearm, the Pistolet Automatique de 7 millim.65 genre "Ruby". A very international piece of weaponry, it was closely modeled after the American John Browning's M1903 by the Belgian Fabrique Nationale de Herstal, and was produced primarily by the Spanish Gabilondo y Urresti-Eibar firm (the official "Gabilondo Ruby").
