The Russkis produced a slightly larger bullet (9x18mm Makarov) for it and after that advised all the satellite states for making a gun like it, which is how you will get the FEG PA-63, CZ 82 and PA64 military surplus pistols.Among my most prized rifles can be an American-built Mosin m/91 which was reworked from the Finns at some point in its life.
