Avoid suede lined holsters,,,
Avoid suede leather as a liner,,,
It seems like it would be soft and non abrasive,,,
But what happens is that dirt and grit embed in the suede nap,,,
Eventually (unless you clean it religiously) it will act like sand paper on your gun.
Suede leather (and most all garment and upholstery leather) are chrome tanned,,,
This means that the leather is tanned using chromium salt solutions,,,
If your holster gets wet and stays in contact with your gun,,,
The salts react badly with blued steel,,,
Corrosion will be the next result.
The best lining for a holster is smooth vegetable tanned leather,,,
That's the same type of leather used for the outside of quality holsters.
Look at the cut edge of any leather,,,
If it has any gray-ish color to it,,,
Chances are it's chrome tanned.
