Resistance to corrosion is paramount to wear in a carry weapon. And np3 beats the puss out of pvd’s for corrosion resistance. That’s why the holy grail of gun finishes was and probably still is, a dlc/pvd over hard chrome.

So for holster wear/daily scratch resistance, you're primarily concerned with how hard the coating is. The NP3 Plus is some fairly hard stuff with a Rockwell C hardness of 35-50 which converts to a Vickers hardness of 320-550. As a comparison, the proprietary DLC and AlTiN we use has a Vickers of 2,600 and 3,300(respectively) which in Rockwell C is converted as (RC +90). THEORETICALY (meaning not recommended) as Hardened Tool Steel generally has an RC hardness of 62-66, scratching a hammer from home Depot against a DLC/AlTiN coated slide, should produce wear and scratches on the surface of the hammer well before it affects the pistol slide.
