Wish I had an easy answer for you. I started with the CT grips for the 59xx series and cut them down. I first did a 6906 - a doublestack - then figured out how to do a singlestack. The CS9 was the real challenge because the grip is so short that it interferes with the circuit board.

There was lots of trial and error. I typed up my notes - one line per step - and it is more than two pages, if that tells you anything. The masterswitch has to be removed and filled. The inside has to be ground out and new locating points built. I built jigs to cut the length and edge and locate the retention screw.

It has been kind of a fun challenge, but I wouldn't do it again. However, I really like the CT laser and it has been worth the pain.

Best,

John
