Our local gun shop and range has a brand new Ruger SR9 in the case and I got to handle it Thursday.
All I can say is, the grip is amazingly thin. I had read several articles on the gun before actually holding this one and I knew it was thin but you really don't understand fully what the authors are saying until you actually have one in your hand. It's amazingly thin for a gun with a double stack mag that holds 16 rounds.
Other than that, I wasn't real impressed. It isn't that different from any other polymer framed gun except for the thinness of the grip.
