The V Rad came out in 2007, so it has been a while. The Pro Only Green Star is an all rubber grip with a similar piston shape, from what I can tell comparing it to the images of the V Rad I could find. Not sure how the sizing compares. GP has several Pistol type options you might look at. Their website shows more view of the putter grips than ours, so you might take a look so you can compare shapes of what they currently have.
