The Astra 400 was produced in a limited quantity for the German military during the Second World War. Only around 6,000 pistols were produced for the contract, and they were shipped to Germany in 1941. The serial number range is 92851 to 98850. These pistols were not marked with any German proof marks, as they were imported from Spain. The Nazi contract Astra 400s are highly sought after by collectors due to their rarity and historical significance.
