In Turkey, anyone 18 years old and older can purchase/own a blank-cartridge firing pistol at 10 percent of the price of a “real” gun, and no firearms license is required for their possession. They look and sound like a “real” gun because of their shape, size, and working principles; however, the barrels of these guns are blocked fully or partially, so they are not rifled. They are designed for use only with blank cartridges. The original barrel of a blank pistol is produced from a material that cannot usually withstand the pressures produced when firing a conventional, bulleted cartridge. Moreover, the original chambers are usually of a diameter that is incompatible with conventional bulleted cartridges; however, by making simple modifications to the barrel and chamber, blank pistols can become compatible with both conventional bulleted ammunition and modified blank cartridges that have been fitted with a projectile. This paper describes the following modification methods, after which the blank pistols and cartridges fired are no longer functioning as manufactured: removing the obstruction from the barrel; removing the partial obstruction from the barrel; sleeving a smaller diameter tube into the original barrel; using a replacement barrel; and rifling the original barrel. Based on this review, the authors advise that new legislation is needed regarding the development of production standards for blank-cartridge firing pistols, which will make them incapable of being easily converted to dangerous weapons. In addition, legislation is needed for greater restrictions on their ownership. 10 figures, 1 table, and 7 references
