The SPAs: Argentina's full-auto pistols, Part 1
Like most countries that manufacture guns, Argentina has also done its share of research trying to come out with a decent (light, compact, accurate, controllable) full-auto pistol. The whole thing started at the Government-owned Fábrica Militar de Armas Portátiles “Domingo Matheu”, in Rosario, Santa Fe Province, in 1974 as an in-house effort. Being an established licensed manufacturer of the FN Browning Hi-Power, the factory found it proper to use it as the basis for what was called the SPA (Sub Pistola Ametralladora, Sub Machine Pistol).
