The Astra 300 is a Spanish semi-automatic pistol that can be loaded with 6 or 7 cartridges in a stick magazine, depending on the caliber size (7.65mm or 9mm).

In 1937–1938, the USSR purchased a small number of Astra 300 pistols from the Spanish Republic.

In particular, the People's Commissariat of Defense of the Soviet Union Kliment Voroshilov handed over the M300 of the luxury model to the Soviet pilots such as Vasily Stalin, Timur Frunze, and Sergey Mikoyan.

Larger weapons, with significant "representative" dimensions, such as the 7,63-mm Astra pistols of models 901-903, were handed over either to military leaders or to the highest commanding staff of the NKVD.
