First couple of hybrid holsters bought were supertucks horse hide. They all wore holes in pants from the clip attachment screws, and never could permanently stop the squeaking. None of my iwb hybrids cover the outside of the muzzle, but hey are worn at 3 or 4 oclock. Can easily see where wearing one at 6 oclock could wear through, especially with any slight bending motion.
Any of the hybirds bought were modified slightly, mostly by very slightly modifying the plastic molded part for better fit and ease of holstering.
