Lima, I just got myself a G27 yesterday and it is a nice little package (relatively speaking) but I can see why you wouldn't like it. I think my ginormous hands are the only reason this grip seems comfortable. If the heel of my palm were on the bottom of the backstrap, I don't think it would work as well. As it is, the backstrap swell sits in the "pocket" of my palm. I still think the M&P's ergonomics are superior.
