May end up with the excaliber oersize finger groove. They look the bigest of all I have looked at. They even have a spot for your whole pinky. I'm thinking this would keep the rear corner of the grip frame out of the palm of my hand.
I may have to grip a bisley frame the next time I'm in a gun shop that has one. I never liked the way they looked but I'm finding I like to shoot more than I like to look cool anymore.
