I recently bought a mint 240mp and wanted to try it with a grip. I had an m9 for years and used a thumbs up. After searching around I bought the M-Grip from Eric Paulson at Photo Equip, (Photo Equip | The finest photographic accessories for the discriminating photographer since 1989) This thing is beautifully made, machined from single block with a very comfortable soft rubber grip. After trying it out, I returned my gariz half grip. It makes handling and focusing so much more stable. I highly recommend this grip.
