Scuffs and scratches are one of the most frequently cited downsides of Kydex holsters. However, the reality is a bit more complicated than some would suggest. For one, the gun’s finish matters. Some finishes scuff and scratch more easily than others. A properly applied Cerakote finish, for example, shouldn’t experience any damage from being holstered and drawn. Second, if you choose a well-made Kydex holster, the retention system will rely on the trigger guide, not the slide. This reduces the surface area in contact with the holster and therefore minimizes the opportunity for scratches. A well-made Kydex holster will also have a smooth interior. This, coupled with regularly cleaning the inside of your holster to remove dust and debris, helps reduce friction, which is what causes the scratches and scuffs.  Finally, leather isn’t immune to leaving rub marks either. Repeated contact between two surfaces will, eventually, result in marks. This is something to be mindful of when you buy any holster, not just a Kydex one.
