Any chance you have lost interest in it? Asking for a friend...They're not that unusual or rare, but probably my Polish P83 in 9mm Mak.
It's one of the later, and in my opinion better variants of the Mak design. The DA/SA trigger is nice, and the heel mag release is a nice rocker switch instead of the stiff, bent sheet metal of the regular Mak. Almost the ENTIRE gun is made of sheet metal. The slide is two pieces of stamped sheet metal nested inside each other, and the frame is two pieces of sheet metal welded together. You can see the seams and the welds of how it's built.
They were super cheap several years ago but then went extinct on the primary market.
