My only complaint initially are that they are not a perfect fit. I imagine it is due to the thinness of the grip, and Jon8357 over at berettaforum.net noted the same issues. I don't think it will cause any function issues, but is something to be aware of just in case.
I did not have the same issues with the length of the grip screws and magazine interference as Jon8357 did. I am not sure if there is maybe some minor difference in frame thickness or what exactly since his gun was a 92D and mine is a 96D.
My only other issue that is more a personal preference than a legitimate complaint is the large smooth space on the upper portion of the left grip panel.
The way I grip the handgun, this is a prime gripping location for me and I prefer a very aggressive grip texture in this area. So to fix the problem, I did what I did to my Glock and added some grip tape.
I may be putting the cart before the horse a little since I have not run any rounds through the gun with the new grips yet, but somehow I doubt it.
I should be on the range later this week and get some live fire through the gun with the new set of grips. I have a lot of catching up to do on the Drill of the Week. Unless the grips start causing some type of unforeseen problem, I see no reason to switch back to the stock grips. I even think that I might see a measurable performance gain with these grips in terms of split times, it is just a matter of how much. There is definitely an improvement of "feel", although I know that can be misleading and the true test of "better" is measured performance. We will see how they stack up on the range later this week.
