I have a CBST knock-off - very happy with the fit, the draw, etc. I am not too happy with the back of the holster that is rough in some areas and when it is hot/humid it really bothers my back. Obviously adjusting it all the time is not an option.
When I say rough, I would compare it to maybe half the length of the threads on a bath towel. Weird, I know - but trying to give you an idea.
So, how can I smooth out this rough leather? High grit sand paper?
