I'm not sure about the website address, but check out the grips from VZ Grips. They make some of the grips that Wilson sells (with the Wilson medallion in the center) so they might make the G10 grips too. (Specifically they make the grips that are currently on my CQB: Black Linen Micarta) Between the checkering on the frontstrap and the mainspring housing, and the checkering on the grips, I think I am good to go unless the gun and I are completely coated in oil.
I have a set on my 2 bobtails, my EMP and my Tac Pro II that has a mag well. He will make them the way you want them. I asked him to cut a hole for the mainspring housing pin for my bobtails since I liked the look of the Ed Brown Grips...no problem at all.
