The Firearms and Swords law revision in 1971 introduced more safety changes. It requires all metal model handguns released thereafter must be completely blocked up the entire barrel in metal and painted in white or yellow color except the grip. Since then, all metal model handguns produced were either painted in gold color or gold plated which is accepted as yellow color. Even the pre-1971 produced metal model handguns were needed to be blocked up the entire barrel and re-painted in yellow / gold color in order to comply with the law. However, the metal modelguns for export (mainly to RMI) can still be made in black color. Moreover, plastic modelguns started to get into the market as it is not governed by the law and can be produced in black color for more realistic look.
