Ruger LCR - Larger Grip?

[Black Dog]

I have recently acquired a Ruger LCR. The Hogue rubber overmolded grip is superb. But if the grip was a little longer, it wjould fit my hand and little finger better, and afford more control. Does anyone here know whether the Hogue rubber overmolded grip for the Ruger SP-101 or the Ruger Redhawk would fit the Ruger LCR, or are the grip pegs on each of these revolvers a different size? I emailed Hogue Customer Service but have not heard back. Black Dog
