New 226's have a one piece grip while older 226's have a 2 piece set. There are internal differences between them. As of now, there are no other grips for the new models. This will probably change in the future. Have you handled and compared the different grips ? I love the new model. I converted my old german 226 & 228 to the one piece grip. The only downside is the new grip is more difficult to remove and reinstall. There is a t-handle tool(it comes with the conversion set) that makes it easier, but I don't know if it comes with the new models. Whichever model you chose, you will not be disappointed.
