This seems like a good place to post this little tip on grip screw removal:
We always had a tough time removing "frozen" grip screws, especially with the extremely small 1/16" Allen head. I don't want to say how many early carbon fiber grip sets I had to eat because I did not know this trick until just a couple of years ago when I phoned Loctite and asked them if they had any advice. . . . . and did they ever! Here is the best way to remove the grips screws from your R9 pistol:
Take an old school soldering iron, the straight tipped "pencil" type, not the high tech "gun" looking thing. Plug it in and let it heat up for a few minutes. Once it is ready, take it and carefully place it inside the Allen head area of the grip screw with the tip hitting the bottom of the indent where the Allen key goes. Keep it there for about 15 - 20 seconds at the most!. . . . leaving it there longer could damage the grip panel by melting it with the heat from the soldering iron. Put the soldering iron down in a safe place, such as it's holder, and quickly take a fresh 1/16" Allen key, place it in the screw head, "load it up" and the briskly . . . . Twist it with a snap counterclockwise and the screw should spin freely out from the frame. The trick here is simply this. . . . Speaking with a Loctite Tech, he mentions the Loctite cement melts around 300 degrees back into a liquid form, thus releasing it's hold on the screw and the frame. It's that easy and will safe your grip and you from destruction. Now, go swap those grips for something different with confidence!
