Russian military overpressure variantsEdit
The Russian military has developed specialized 9×19mm cartridges that use relatively light bullets at high muzzle velocities for both pistols and submachine guns to defeat body armor.[36]
Besides enhanced penetration capabilities, these overpressure variants offer a flatter trajectory and lessened recoil. The increase in service pressure causes a rise in bolt thrust, so the use of this overpressure ammunition induces more stress on critical weapon parts during firing. After initial research, conducted since the late 1980s under the codename "Grach", the Russian armed forces adopted two specialized 9×19mm variants.[37]
Other variantsEdit
VBR-B produces specialized bullets for this cartridge, a two-part controlled fragmenting projectile and an armor-piercing bullet that features a brass sabot and a hardened steel penetrator. These are designed to increase the content of the permanent wound cavity and double the chance to hit a vital organ.[42]
