Apache pistol? Plus there is a problem with the link.

I am' really into weird revolver desings, and you, sir (Or miss?), have gotten 5 stars

Best weapon idea ever

A couple amateur mistakes but for an amateur3D photo its pretty damn good

I see three amateur mistakes in the 3D modeling.
(a) The image isn't anti-aliased. You can see it most clearly on the blade and the handle.
(b) You only have one light and it is WAY too bright. Cut the brightness by half, and then add two more lamps that are much dimmer and don't generate shadows. Those lights will fill in the details that the primary light misses.
(c) The model isn't high enough resolution in terms of polygons. I can see the polygons in almost all of your round edges, particularly at the handle and the base of the blade. And here's the advice I give to almost half of all 3D submissions on NG: BEVEL YOUR EDGES. The rectangle under the hammer, the triangles on top, the barrel, the gears, the handle; so many places in your model have those infinitely-sharp edges that are unrealistic and reveal the fact that it's computer generated. Edges on real objects are just *slightly* smooth at the corners.

I have no problem with the concept and design, but LegolaSS already made recommendations for you that you might want to employ. Keep trying. 3D art is like algebra; you have to do 20 steps exactly right or the whole thing can fall apart.
