Very nice look so far. Going to use this in something or just for fun?

Using it as practice for the process of getting a weapon into dota. I'll be importing it into zbrush after this and practicing my sculpting.

Other than that just playing with the processes. My goal is to be able to work through the whole process and get a weapon I design onto the market place.

There might be a few places where you can cut down on some polys if you're going to put it into DOTA. Not many that I can see though. Looks rather clean.
Unless DOTA doesn't use normal maps. No idea if it does. I should look into stuff like that. I do love making weapons, and some games do let you make weapons for them. heh.

Can't wait to see what you have after you take it through zbrush!
