The are out to the sides as far as they will go in this picture:
And that is fine for me.
The real "problem" is that the rivets holding the plastic to the canvas belt are not positioned properly. The should be further out to the side. This is an easy mistake, and I made the same mistake when I built an RS this summer. It's an easy mistake because the RS belt comes with formed indentations that fools you into thinking the rivets should go there. If you're not thinking about it, it's very easy to just go with those. That creates the problem that the drop boxes cannot sit further out to the sides, since the are blocked by these rivets.
