The FBP m/948 was designed in 1940 by Gonçalves Cardoso, an officer in the Portuguese Army. However, World War 2 halted further development. After the war, the Portuguese Army required a simple to produce submachine gun. The m/948 was produced at the Fábrica do Braço de Prata weapon factory at Lisbon between 1948 and 1961. The gun was used in the Portuguese Colonial War in Africa.
The m/948 is full auto only. The later m/963 introduced in 1961 allowed for semi-automatic fire.
