What is "modelguns"

Modelguns are Japanese replica or toy guns, which are usually made of zinc-alloy or plastic materials. Most modelguns are designed to replicate the physical outlook and in full scale of the real gun counterpart. Some bear the authentic markings that make them look very realistic like real guns. Some are even made to copy the internal mechanisms and operate like real ones using tiny bit of gunpowder (the cap) to produce firing sound, spark and the operation, but strictly not able to shoot any projectile. There are very strict gun control laws in Japan to restrain the mechanisms and material of modelguns so that modelguns appeared in the Japanese market are safe and cannot be converted into something that can fire any live cartridge or projectile.
