great start for such a hard one. but it doesnt look right. i think it's because the metal (gray) part is shorter that the butt of the gun (brown part). i think the metal is supposed to be longer than the butt. could you edit that?
I tried making the metal longer than the butt... O_o
Ahh well... i'll edit that tomorrow...
[EDIT]
Meh... I couldn't be bothered waiting just to make a tiny edit...
Here you go... hope you like
...and yes there is a difference believe it or not... O_o
