A 9x18mm Makarov SP8 gzh cartridge holding a 3.9 gram frangible hollow-point semi-jacketed bullet with a lead core in a plastic plug with a reduced charge in a bimetallic case.
Developed in the mid-1980s by TsNIITochMash in order to provide a low penetration cartridge to minimize the destruction and over-piercing of objects with low structural strength (for example, during counter-terrorism operations in an aircraft) and still provide a significant stopping power effect along causing substantial adverse effects on the target after impact.
