The semi-circle shaped ends are causing a bit of trouble. I've tried different ways of trying to model this indent but everything I've tried ends up in god awful topology which would require a lot of clean up, or the shape just doesn't turn out right. Just wondering what the most efficient way of doing this would be?

There's also 4 of these indents on the part that goes around it, so a mirror would be mandatory for perfect symmetry (which I'm already using).
