The 9×21mm IMI cartridge (also known as the 9mm IMI or simply, the 9×21mm cartridge) is a pistol cartridge designed by Israel Military Industries.

History[]

The cartridge was intended as a substitute for the 9×19mm Parabellum cartridge in places where civilian usage of military service cartridges is prohibited.

Design Details[]

The 9×21mm cartridge was based on the 9×19mm Parabellum cartridge. Compared to the Parabellum, the IMI cartridge has a casing length of 21.15mm, whereas the Parabellum's casing is 19.05mm. The 9×21mm's bullet itself is seated much deeper in the casing, making the whole cartridge's length similar to the 9×19mm.
