Holster wear comes with being holstered. I can't say that I consider it desirable, but I don't mind it in a carry pistol because I accept it as an inevitable consequence of their use, like mileage, tire wear, and so on for a car.
I do have one pistol that is not a safe queen in that I enjoy shooting it, but which was purchased with a "pride of ownership" motivation. I try to keep it real nice. Other guns I clean to maintain functionality and don't worry about cosmetics.
