I have a couple very similar 696's and my favorite grips after trying several are the Altamont Altai K-round conversion grips.
They are similar in shape, comfort, and pointing to a Miculek grip.
The rubber grips are fine for the range, but for carry they can hang on your clothes.
These plywood grips are so comfortable to shoot with Specials I never went back to the Goodyears.
If you try a set of these, get the ones
without the medallions.
That leaves the left panel a little thinner and easier to speed load.

They have excellent customer service.
One of these sets stood a little proud of the backstrap.
They said send it back.
Got it back about a week later and was perfect.
No charge except the one way ship and that wasn't much.
