I just installed the new version of CT grips on my Glock 23. It took me a while to get used to the new lumpiness of the grip. After 1/2 hour at the range I still haven't got them sharply zeroed and will have to go back and redo it on a bench rest -- the 23 has much more recoil than my 19. Anybody have these grips on a Glock? How are they working out?
