History of 9x18mm Ultra Ammunition
Introduced in the 1930's through a collective effort of Gustav Genschow and Company (GECO) and Walther Arms, the 9x18mm Ultra was developed at the request at the German Air Force as a replacement for the .32 ACP. The .32 ACP was the most commonly used military pistol cartridge in the German military at the time, and many found it lacking in performance when compared to other cartridges available. It was hoped that the 9mm Ultra would provide the more powerful cartridge that was suitable for military use. As Germany descended into World War II, development of the cartridge was set aside.
Ballistics of the 9X18 Ultra are Similar to the 9x18 Makarov, with the most common load being a 100 grain bullet with a velocity near 1050 feet per second at the muzzle. Although not a stellar performer, it was a huge step up when compared to the .32 Auto cartridges in use at the time. Unfortunately, it was very close in performance to the already established .380 ACP, this performance similarity is most likely what kept the 9mm Ultra from gaining a stronger following.
In 1972 the cartridge was revived as Walther introduced a model of their PP pistol called the PP Super. This pistol was chambered in in 9x18 Ultra, but the cartridge was re-named the 9x18 Police. Soon after, several other German and Italian companies began producing pistols and cartridges intended for the law enforcement community. Unfortunately for Walther and GECO, the German police decided that they would adopt the 9x19mm Luger as their duty side arm cartridge. This move made sales drop sharply and shortly thereafter, Walther stopped making pistols in this caliber. Since then there have been no attempts to revive this cartridge. Today, Fiocchi offers one load in the 9x18 Ultra, marketed under the "Police" moniker. No other major manufacturers produce an appreciable amount of 9x18mm Ultra ammunition.
