So I can see that you design weapons, mainly guns. I design weapons as well, mainly things with blades. Check out my gallery sometime. I don't have very many designs up yet, but I could use some feedback on some of them, and there are some more coming soon!
Or maybe the grip is a little big? It's all reletive. This design is actually supposed to be 100% workable, the reason for the tall frame has to do with internal mechanisms, particularly for switching calibers and the quick change barrel system.
