What do you intend to do about the grips? I have a MGC with red 9 grips. Unfortunately, the MGC frame is still too large for a real replacement set. I felt I'd be loosing accuracy if I modded the MGC frame to accept a real set.
I will either try to find a set of MGC grips for sale, or I have another set of MGC grips from another gun which I think I might cast them in resin and paint them black (since the grips on the ROTJ blaster were black).
