Pistol F. Ascaso

The 400 was considered heavy as in order to handle the power of the 9mm Largo round in a blowback action the 400 had a reinforced slide and tough spring. It gained fame among Spanish African and Civil War veterans as a strong and reliable pistol. This was especially so under mud and sand conditions, due to the nature of the internal hammer, protected from external elements and debris. A powerful pistol, original 9mm Largo Spanish military loads were comparable with.38 Super factory loads.

The Spanish War Ministry of King Alfonso XIII began tests in 1919 to replace the Campo Giro pistol as the standard military sidearm. The 9mm Largo Astra modelo 400, patented by Pedro Careaga, was selected for the Spanish Army in August 1921, and was also adopted by other Spanish Armed forces. Astra pistols were supplied to Republican Spain and to the Basque government which controlled the plant until the Bombing of Guernica in April, 1937. Astra pistols were subsequently produced for Nationalist troops, while Republican forces made approximately 22,000 copies of the pistol in Terrassa (marked F. Ascaso) and Valencia (marked RE for Republica Española). Astra production after the civil war was for Nationalist troops except serial numbers 92851 to 98850 for Nazi Germany. Astra continued private production until 1950 even though in 1946 the Spanish military adopted the Star Model A as the standard sidearm. Spanish military inventories were sold to civilian wholesalers between 1956 and 1965. A total of around 106,175 pistols were produced.

The Astra 400 is heavy compared to many contemporary service pistols of the time like the Tokarev TT-33 but is similar in weight and length to the Colt 1911. The Astra 400 was designed to be safe to fire with a simple blowback action unaided by any breech-locking devices. This is only possible with a heavy slide and strong recoil spring. It was fitted with an internal hammer which was considered very hard to cock. The pistol also featured grooved finger grips and left sided combined slide lock/safety behind the trigger guard. Military issue pistols have wooden grips and lack some Astra-Unceta markings, while pistols produced for the civilian market can be distinguished by the hard rubber grips, full commercial markings, and the presence of several nickel or chrome-plated small components. While it was primarily designed to chamber and fire the 9mm Largo cartridge, it can also accept other 9 mm cartridges including the 9mm Steyr, 9mm Parabellum, 9mm Browning Long, 9mm Glisenti,.380 ACP, and.38 Super with various degrees of success—The Astra 400 doesn't always feed shorter cartridges reliably, specially the 9mm Parabellum; According to Ian V. Hogg, this compatibility was accomplished with a combination of loose enough dimensional tolerances and an unusually long firing pin allowing it to reach and detonate the primer of shorter cartridges. Hogg also stated that such practice should not be attempted on worn out pistols; other authors—including E. C. Ezell recommends only using 9mm Largo cartridges for safety reasons.
