Currently it is being used by some military units in the North Caucuses region, and is replacing the Makarov PMM as the main sidearm of the Russian Ground Forces. While the MP-443 is the military version, the MP-446 is the sporting derivative of it. the strangest feature of it is definitely the ability to use overpressure armor percing rounds, such as the 7n21 and the 7n31
