Awkward feel in my hands - FAB Defense Tactical Folding Grip

I am a fan of Fab Defense products but this one fell short in my opinion. For the most part it is well constructed. I just noticed that when it is in the vertical position, it wobbles a bit. That coupled with it feeling too bulky at the top and too little material at the bottom. I have wide, but smaller hands which might be why it doesn't sit well with me.
