I thought that the texturing was lacking grip to.
I found the texture almost painful with extended use in bare hands, because the tips of the plastic "checkering" was so sharp.
I've heard a lot of complaints about that on several guns, in addition to CZ.
I just gave the grips a few quick swipes with sandpaper. The grips are still agressive enough so that they don'tmove easily in your hand, but are no longer uncomfortable for me.
