The 9×18mm Ultra is a German pistol cartridge.^[1]

Description

It was originally developed in the 1936 for use by the Luftwaffe, but was not adopted at that time.^[1] In the 1972-1973 time frame, Walther introduced the Walther PP Super chambered in the cartridge for the West German Police.^[1] The Walther PP Super was discontinued in 1979.^[2] The cartridge was made available to the civilian market in 1975.^[1]

In addition to the Walther PP Super, the SIG Sauer P230,^[1] Mauser HSc-80,^[3] and Benelli B76^[1] were also produced in 9×18mm Ultra.

The 9×18mm Ultra (.355-inch caliber) is not interchangeable with the 9×18mm Makarov (.365-inch caliber), as the latter uses a larger diameter bullet.
