Carcano is the frequently used name for a series of Italian bolt-action, magazine-fed, repeating military rifles and carbines. Introduced in 1891, this rifle was chambered for the rimless 6.5×52mm Carcano cartridge (Cartuccia Modello 1895). It was developed by the chief technician Salvatore Carcano at the Turin Army Arsenal in 1890 and called the Modello (model) 91 or simply M91. Successively replacing the previous Vetterli-Vitali rifles and carbines in 10.35×47mmR, it was produced from 1892 to 1945. The M91 was used in both rifle (fucile) and carbine (moschetto) form by most Italian troops during the First World War and by Italian and some German forces during the Second World War. The rifle was also used during the Winter War by Finland, and again by regular and irregular forces in Syria, Libya, Tunisia, and Algeria during various postwar conflicts in those countries.
The Type I Carcano rifle was produced by Italy for the Japanese Empire prior to World War II. After the invasion of China, all Arisaka production was required for use of the Imperial Army, so the Imperial Navy contracted with Italy for this weapon in 1937. The Type I is based on the Type 38 rifle and uses a Carcano action, but retains the Arisaka/Mauser type 5-round box magazine. The Type I was used primarily by Japanese Imperial Naval Forces and was chambered for the Japanese 6.5×50mm Arisaka cartridge. Approximately 60,000 Type I rifles were produced by Italian arsenals for Japan.
