9mm LARGO

The 9mm Largo (aka 9x23mm Largo, 9mm Bergmann–Bayard or 9mm Bayard Long) is not to be mistaken for the popular 9mm cartridge. It was developed around the turn of the 20th century for the Bergmann Mars pistol. It was quite powerful for its era, and adopted by the Spanish Army soon after its introduction. Today it is a relic, and usually available with the 9mm’s 115 or 124 grain full metal jacket bullets (if it is available at all).
