Just a suggestion but have you thought about using Terro-Tuff? After several years of using stall matts Dan Keffeler told me that he was switching to Terro-Tuff because it adhered better and lasted longer than stall matts. He knows a thing or two about that kind of stuff.It also comes in lots of cool colors.
Terro-tuff is good for tactical and bush handles, but is not the same as rubber.
Consider it a slightly softer and grippier Micarta. It is similar to what many people get when they make home made MyCarta.
What I use is 3/8" neoprene sheets. Most of the knife suppliers carry it. You can get sheets and sometimes in blocks. A good resin, like G-flex, will adhere the neoprene well. Dye the resin black and the seam is invisible. I have used horse stall matting, but it is pretty ugly stuff. The only place I can see horse stall mat being the perfect material is on chopper, machete, or hatchet handles.
