I'm new here and would like to come up with the following question: I've two GP9s where I chopped the noses. On the older P2k it was possible to remove the upper part of the metal-weight which was hold by a screw. Now I'd like to put the shells of my low-nose GPs on the new drive with the QSI-decoder. Is it still possible to remove the upper part of the "nose-weight"?
