Be aware that all 9x18 pistol cartridges work in all 9x18 9mm guns.
However, only Makarovs made in East Germany, Bulgaria, Russia and China deserve the "Makarov" name.
Having said that, the general rule is that East German Makarovs are the most respected (fit and finish) followed closely by the Chinese, Bulgarians and Russians.
Other pistols chambered in the 9x18 cartridge are second best in terms of build quality and longevity. The Polish Makarov is, like the aformentioned, all steel and highly regarded, even though it's not the same design.
