At least now i know how to sucessfully rig and compile a weapon model.
In fact much faster and easier then most character models because guns only have 100% weights.
The gun itself isn't very well optimized since i just keept the 4 seperate materials for gunbody, silencer, magazin and lamp attachment and the world model is exactly the same as the viewmodel.
As for the silver/gold version, also just a quick attempt to make them distinctable.
