9x21mm IMI

The 9x21mm IMI pistol cartridge was designed by Israel Military Industries for those markets where the 9x19mm Parabellum cartridge cannot be purchased by civilian users, notably Italy.

Design
Based on the 9 mm Para cartridge, the casing was lengthened from 19 mm to 21 mm. The bullet sits slightly deeper, which results in the same overall length as the 9 mm Para cartridge.

Performance
Performance is similar to the 9x19 catridge, in terms of velocity and energy.
