I've had the Talons on my CM9 (my primary EDC) for about a year, and today I finally put the grips on my other two that I typically carry. I expect they'll be especially helpful on the squirmy TCP.
For only a couple of bucks, you can order a decent size piece of Talon rubber grip tape to use on guns they don't offer cut grips for. In addition to running Talon grip tapes on all of my Glocks, I also use it on the front strap of my Kimber Compact 1911. I have also added a bit to the extended mag base plates. It's pretty good stuff and works better for me than skateboard tape.
