Tenifer and Melonite are metal surface treatments. They vary slightly in chemical composition but accomplish the same thing. You cannot see the surface treatment - by any name - under the finished slide.
Tenifer isn�t performed in the U.S. ... Melonite (and other trade name processes) is peformed in the U.S.
Pistol slides made in Austria have Tenifer ... Pistol slides made in the U.S. have something else - like Melonite.
Glocks slides used to be parkerized ... Now they have an applied finish of some kind.
Perhaps that helps clear things up.
