I recently inherited my grandfather's Hi Power that I plan to run for the next year in heavy IDPA use in preparation for the 2015 IDPA World Championships in my home of Puerto Rico. But I'm kind of worried of destroying the finish on the gun with a kydex holster. How much of a worry is holster wear? Do certain types of holsters prevent wear and tear? I see recommendations for smoothed-inner holster, kangaroo leather, lined holsters, etc.
My other pistol is more of a tool and I don't particularly care if it gets dinged, but this I kind of do care. Am I worried over nothing or is there a holster I can get that I don't have to worry about the finish wearing off?
