Gun Model Issues (please help)

So this is my first time modeling anything like this, and I feel i’ve come a long way. Unfortunately i’ve come across some problems that I can’t seem to figure out how to fix. As you can see in the pictures below, the handle is oddly deformed in certain areas, and I can not seem to achieve the smoothness I want no matter what I try.

If anyone can please give me some advice on how to fix these issues it would be greatly appreciated. I know it’s not that great, but I really wish to improve, so any criticism on anything else is also greatly appreciated! :slight_smile:

I don’t really see whats the problem, to me it looks fine.
Do you want the handle to be evenly think everywhere?
