The Pistola Mitragliatrice Fiat Mod. 1915,[1] commonly nicknamed the Villar Perosa,[1] was an Italian portable automatic weapon developed during World War I by the Officine di Villar Perosa.
As it was designed to use 9×19mm ammunition, it is said to be the first submachine gun, although not a true submachine gun by modern standards.[2] Due to its extremely high rate of fire, it was nicknamed Pernacchia (literally raspberry, in that context meaning something like fart gun[1]) by its operators.
