I am looking for a free 3d model of the Smith and Wesson 500 Magnum Revolver. A complete blue print would also help. I just need to tweak it and make a SciFi handgun out of it. Anyway I’ll try to model using reference images. 123D catch will generate messy geometry and I don’t have a licence yet to own a gun and it’s pretty expensive 
so I have to rely on reference image my model will only be 98% correct to the original S&W’s product design because no actual reference, just some images of the gun
