Maybe the fact that you haven't posted any wireframe shots or such but only two shaded shots of it affect how many people comment on it, and besides people can be busy. No need to expect responses after only a few hours.
Looks pretty good but as I noted above, no wireframe usually doesn't help anyone help you. The only thing I can see right now is that the handle is quite thin and you have some very sharp edges by the trigger guard.
EDIT: Fixed the text a bit, and wow you responded fast.
