Grip Info

I have a New Model Blackhawk Revolver in 41 Cal. with a internal locking device under the grips. I'm looking to replace the laminated grips with rubber ones. The problem is Houge does not make grips for that revolver (It's a Post 2006 Model). I'm in the process of getting in touch with Pachmayr on this matter. I'm looking for oversized grips for this weapon. Can anybody help me on this problem???
Thank you
