Which is harder, NP3 or Roguard?
NP3 will be more abrasion resistant because of the Nickel. However, keep in mind that Roguard will wear much better than Bluing, Blackening or Parkerizing! Regardless of the finish, holsters manufactured from Kydex or Nylon seem to wear the finishes faster than leather or horsehide. The NP3 is harder than Roguard.
