Degueldre pinfire revolver. ~2400 triangles, 1024x1024 diffuse, normal, and specular. That weird seam line on the back of the grip is a render error, ignore it.
Looks real nice dude, the one thing i would say is that your lighter metal should be darker in the diffuse, so you can push the reflection contrast more than the diffuse contrast. As that is why that material would be brighter, because it is more reflective right? A brighter diffuse there would tend to describe another…
