The Rami has a screw bushing in the frame. Take the grips off, you'll see a bushing that the screws go into. That bushing will also screw farther into the frame. Take care not to go too deep or your grip screw will catch on your mag. Also the grips have little notches to lock onto the bushing. When you screw the bushing in a little, just make sure it's orientated correctly for the grips to fit correctly.
