How an Astra model 400 works

The Astra modelo 400 was a Spanish service pistol produced by weapons manufacturer Astra-Unceta y Cia SA. as a replacement for the Campo-Giro 1913/1916, which had also been chambered in 9mm Largo.

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.
