I believe that GJ shut down his website, but he is still making grips, I have a set of his and I also have a set of Tony G's grips. I like both, G.J. grips are very nice but not a true custom sized to your hand, you would have to shape it a little like I did if your hands are small. Tony G will ask you for a couple of measurments and will make the grip for your hand at a very reasonable price.
Also, there's Dave D. on this forum that makes very nice grips also. Dave's grips are also true custom grips. Give Dave a PM, I'm sure he'll send you a few pics of his work, or you can do a search on here. I know he's posted a few pics.
