A good-looking grip is the sambar stag. I bought a set for 89.00 in 1980 for my mod.28-2 in 44Mag., before getting into the fitting, I put a set of pac. grips on it, while shooting it I realized how much I liked them, so I have never fitted the stags but they sure are purrtty, got some of the rough brown textured antler lines in them, maybe I'll get around to fitting them sometime soon the smith has a bead blasted nickle finish 6.5" BBl. As Larry said there are all kinds of materials and prices available out there. I also like the micarta material. the white or other light colors could be scrimshawed very nicely as well.
One of the knifemakers may know where you can get your desired material for the Python's new Scabs and then you can carry it in your Scabbard.
