I use Pachmayr grips on my 29-2. The "square butt" ones. I think they are the Presentation series not the Gripper, but I'm not sure about the name, sorry.
I use the rounded butt finger groove ones on my model 28. On the 28 I find them a huge help. On the 29, I consider them a virtual necessity.
Full house .44 Mags and stock grips hurt me shooting the 29. Pachmayrs help a lot, turn hurt into discomfort, and because of that I limit my model 29 loads to 240s between 11 and 1200fps. The gun isn't unpleasant to shoot then. Still plenty stout.
I have other guns for heavier .44 mag loads.
