"According to Dutch law a gun is a weapon and because of this it is illegal to produce or sell weapons in, from or by a Dutch company.
Replica guns and knifes are a category I weapon according to the Dutch Weapons and Munitions law(Wet wapens en munitie). Indeed according to that law any toy or other gun that so closely resembles a real gun that it could be used to threaten someone is forbidden. So we would not be able to produce your model for you.
A weapon so small as that it could not be conceived to be a threat could be OK. However this is my own, non-expert opinion. So it depends on the size and material you would like to have it printed in."
