Taurus "The Judge" Public Defender Poly

This time I tried to model a real firearm, the Taurus "The Judge" Public Defender Poly.
After a lot of work, I have achieved excellent quality, I know it is not perfect, so I accept any criticism or suggestion.
The following 3D model has a 4K texture, and ready to use with any graphics engine.

The following renderings were made in real time with Unreal Engine 4.
