The original grip bleg.
This is the new 642 with the Pachmayr grippers I found at the gun show last weekend, with the stock grips on top for comparison:
You can see why the grippers wouldn't be that great for pocket carry. HUGE. The other thing about them is that my fingers actually go right on top of the finger grooves unless I hold on to it really low, which actually makes it less comfortable in some ways to hold on to than the little stock grips.
So yes, I'm still looking.
