Yes, I have those grips. Used them for a while as they are a little smaller than the factory grips and are a little harder rubber, but they were uncomfortable and caused some blistering of my palm. I switched back to the originals for a while and then replaced them with a Hogue Monogrip.
The good points about those grips from CDNN are the price and the harder rubber tends to let one draw from the pocket better, but they were still not a good shooting grip. I even tried using sandpaper to smooth up the parts that were rubbing my hands raw. I guess if all you're going to do is carry and not shoot very much, they would be pretty good, but I shoot a lot.
