Hi SCF,
If you are going to file the "pointy bit" of the CCM (KKK to european modellers) you need to take very little off it. A neddle point is no good, just a slam (about 0.5mm) well bevelled centering area. I would look first at the coupler shank where it centers and see if that is where the problem is as well.
Close couplers have been used for many years in europe, most work really well, but evey now and again, you get the odd one that needs to be adjusted. That being said CCM wagons do look a lot better than non CCM wagons.
