About the only thing I have heard of people doing is putting a slip on. Cabelas sells a leather lace up for around 30bucks. Seems to be pretty popular with the buffalo classic owners. I guess because it fits the style of the gun better than others. Here is the link. I know you can find the all brown style also. I think the medium size is what fits this gun.
