A fantasy pirate pistol I made a while ago. It's using about 13.000 triangles and a set of 2048^2 PBR textures (that is albedo, normal, gloss, metallic, occlusion, cavity maps and an SSS-mask).
The concept art is created by Darren Bartley and can be found here
Software used: Blender, ZBrush, xNormal, Photoshop and Marmoset Toolbag 2.
