How hard is tenifer finish on Glock on Mohs scale?

The Tenifer finish on Glock handguns is typically around 5 to 6 on the Mohs hardness scale. This finish, achieved through a nitriding process, enhances the surface hardness and corrosion resistance of the steel. While it is harder than many common materials, it is important to note that it is not as hard as some specialized coatings or materials used in other applications. Overall, Tenifer provides a durable option for firearm finishes.
