Yeah, there's really no substitute for handling a model 97 yourself, but as a point of reference, my hand measures 7 1/4" in length, measured from the tip of my middle finger to the base of my palm. And the factory grip was a good fit for me. But I got the square butt and with max .45 Colt loads, the sharp base caused a bit of pain during recoil. I think the round butt would prevent this. Anyway, I had Grashorns make me a pair of elk antler grips that he beveled at the base just a bit, and they feel much better.
