The case is rimless, brass, straight tapered and Berdan or Boxer primed. The dimensions are the same as the 9 × 19 mm except for the case length. The bullet has the same jacketed bullet as the 9 × 19 mm cartridge. This round was developed in the early 1980s in order to satisfy the civilian market in Italy, Mexico and France, where the normal 9 × 19 mm Parabellum cartridge was prohibited for civilian use. Except for the case length the dimensions are the same as the 9 × 19 mm round, thus adaptation of automatic

pistols to this cartridge was simply a matter of altering the chamber length and did not involve changes to the bolt face or magazine well. Since that time it has become apparent that it is an exceptionally accurate cartridge, rapidly gaining ground as a competition round. There are also suggestions that the extra case length might accommodate an increased charge which could be of interest to military and police. Compatible platforms include suitably chambered automatic pistols.
