I have a horsehide holster that I took a look at today when I took a picture of it for another thread. Looking at it, I'm wondering if this darker area is just wear from rubbing on clothes when being worn, or if it is mold growing on the holster? I'm a lefty, and this is the side of the holster that gets sweat on it if it is hot outside. This area has no smell and the black discoloration will not wipe off with a rag.
Any ideas? If it is normal discoloration from wear, then fine, but if it is mold, how would I take it off without damaging the holster?
Is this normal for IWB horsehide holsters?
