My 97 came with the Aluminum grips also. After shooting 100 rounds through it, I bought the CZ-USA rubber grips and I liked them a lot for about a week. While at an outdoor range, the RSO asked if I liked the Hogue fingered grip on my 75B? I said yes. He then told me that it takes a little stretching and warming up, but the same grip on my 75B would fit on the 97 also. A year later, the Hogue grip is still on and no intention to go to anything else. Your results may vary.
