PS:
Back in 2004 when I was just getting to know my R9 (No. 132), I stripped one of its grip screws using an inferior hex key which I happened to have in my tool box. After pondering the situation for a few hours, I steadied my nerves and managed to remove the screw using a small damaged-screw remover inserted in a power drill set on slow reverse. It's not a job for the faint of heart -- in fact, it may have been a reckless act on my part. Anyway, luck favored me that day. The screw came out with no damage being inflicted on the CF grip panel or the frame. Since then, I've acquired the finest hex key I could find and keep a supply of spare grip screws in the safe . . . just in case.
