The days are long gone that an Individual can import a gun on their own. I would doubt that if you find a gun in a Turkish shop that they will know how to export it. Same as ffl dealers here, most do not know how to import a gun and almost none know how to export. I did both.
Unless its a very unusual or expensive gun I can not see any benefit.
Also: not sure of the available of Turkish gun shops. Of all the counties that I visited and did business in, its not like here when there are shops on every corner.
Anyway, good luck.
