How about calculating the maps using a larger grid size? You'll lose some detail, but if you're looking at 120 A slabs you're probably not looking at individual atoms/residues anyway. I'm not sure if you can do that in coot or whether you need to calculate the map using ccp4 (or some other program) and read in the map.
