is the pa63 better?  thier both  about 100$. is 9x18 russian subsonic?

The PA63 has an alloy frame and is more like a walther and it is liter than the Mak not much of a size diff though. The Mak on the other hand is VERY reliable lots of excessories grips etc cheap mags parts. On the Mak stick with the military surplus East German or Bulgarian models and avoid the commercial made for export models. The 9x18 has a bit more umpf than the 380, some of the surplus ball is really unpleasantly harsh wth the mak and issue plastic grips !
