I have posted this here because the P64 pistol is commonly referred to as a "polish" Mak ,
and is chambered for the same cartrige as the Real Makarov pistols.
I recently purchased a P64 , and found that info on it was VERY HARD to get.
After a LOT of searching - I found a link to the MANUAL , and a new discussion board about the little gun.
I hope these will be useful to others.
