I basically downloaded the free version of XSI Mod Tool and made my own variant of the HK1911
Reference Picture:

Smooth Shaded no lines:




With some lines:




Now if you look down into the ejector port where the chamber is, you'll notice that it's not completed on the inside of the gun. I'm not sure if most people leave that alone or what, but I wanted to make a more or less complete gun so that if you were to do an animation where the character does a systems check on the gun, you could look right down into the chamber and see a bullet there.
I also have done a bit with this model since I took those screen shots, I straightened a few lines here and there, made the magazine and 2 bullets for the gun as well.
Let me know what you think!
