The Astra 400 9×23mm Largo
Didn’t have enough 9mm Largo, to do a more elaborate comparison between it the 9MM Lugar I haven’t been able to find a lot of data on this but the hottest reloading data is 430 foot pounds of energy with a 124 grain bullet, The Astra modelo 400 was a Spanish service pistol in the 1921-1950s, The Astra 400 was designed to be safe to fire with a simple blowback action unaided by any breech-locking devices.This was only possible with a heavy slide and strong recoil spring. #LeverGuns50
