Remarkable 3D model my man, for a good moment I considered this to be a machined cut away of a real Colt handgun. The pitting and scratches on the ferrous metal surfaces is what sold it for me at first to be real... seriously I am still taken aback by the detail you have put into this piece. Top shelf Abiator, top shelf work indeed.
Looks very good. Better than I ever could figure out how to render. Can you say where one can obtain a set of READABLE blue prints, to practice solid-modeling the individual components from? All the prints I've found are incomplete or have sections blurred out so that constructing an accurate model is impossible.
