I got my 97B 2 days ago. The grip size is manageable. Stuart told me that the grip size was comparable to that of Sig P-220. And he was right.
The distance from the bottom of the curve right below the beavertail (?) to the tip of the trigger : DA/SA = about 3.5/3.25 inches. (Sig p-220 = DA/SA - about 3.5/3.0 inches) (CA 75B DA/SA = 3.5/3.0 inches)
And believe or not, the width is not much different from the width of the 82! (approx. 1.25 inches) But horizontally it is longer. And it does feel that way, when you hold it.
At the bottom it is slightly shorter than 2.25 inches. (the 82 = 2 inches) The CZ 75B's is approx. 2 inches as well.
As for its operation, I can switch off the manual safety without a problem. But putting the safety on without changing my grip is awkward. I need to change the grip to reach the magazine release. (it does not bother me. But you may feel differently)
The DA may be an issue for some people. The DA pull of this gun has been reduced to approx. 8.1lbs. So I can squeeze the trigger without changing my grip. If it were the factory setting (11-12lbs), I would have had a difficulty.
The checkering of the grip panels is very mild. I may try the thin aluminum grips CZ Custom carries. More aggressive checkering might be useful for me.
All in all, I am very pleased.
