I tried a search here but could not find anything. How does one lessen the roughness or smooth out the inside of a holster, if even advisable?
Personally, I wouldn't use other than a lined holster.Upgrade!
While some may not agree, I find that lined holsters (with suede) actually attract and hang on to debris more than once raw leather is smoothed out and they also make the holster bulkier. My first holsters (40+ years ago) were lined - but then I saw that it was counter intuitive (for me). I was usually in a saw dust rich environment.
The use of a smooth steel tool should smooth out a holster inside relatively fast, and regular EDC will do the rest.
It will smooth out just from use. I'd NOT use any oil on a holster because you want to keep its stiff shape as long as possible and oil will soften it up.
If it is abnormally rough (have not seen that scenario yet) I suppose you could just use a smooth rounded piece of wood or plastic and just work it in the areas of tight contact, but again with constant use it should smooth out in short order

I've used a hardwood burnishing tool to smooth the rough side of leather but as Chief38 said, "It will smooth out just from use."Don't do anything. What wears the finish on a gun is not whether or not the inside of the holster is rough or smooth; it's poor fit, which allows the gun to move around inside the holster in everyday carry. Smoothing that rough finish will actually make your gun wear faster, because afterwards it will not be held quite as securely.
Whether a holster has a rough interior or a lining, make sure it fits TIGHT when you buy it, almost too tight to use. After short usage it will loosen up just enough to allow easy draw and holstering. Once it gets there, don't do a darned thing further to it.
