I love the sandpaper talon grips on my Glock 23, but have the same problem. Losing a lot of weight would help, but that's not likely to happen any time soon. I'm thinking about switching to the rubber ones. I'm just hoping I like them as much.
I have a blog where I addressed this question, but have a different outlook on it. Just because something hasn't happened, or there is no documented evidence readily available doesn't mean it hasn't, or won't.
