A few years ago I purchased a Colt .38 pistol from a Mexican citizen. The sales transaction took place at the Army base in Guad. There's a special office on base that supervises and facilitates the transaction. The Army issues the new owner ( I'm an American) with a permit and you are allowed to keep the weapon at your home. Transportation of the weapon is essentially prohibited.
