These guns are made of a combination of wood and styrene.
For the guns themselves, I used 3/4 inch thick pine. The triggers, grips and hammers were made of 1/4 inch thick poplar, the trigger guards are 1/2 inch thick poplar, same with the wheels(or whatever you want to call them) on the handles.
The slide bar and safety is made of styrene.
I made these guns for ~The-Simi6
to use for her Noel Vermillion cosplay.
