Naturally, a multi-hour pack case hardening job is going to wear better and longer than a Kasenit job. But Kasenit and other surface hardening methods do work when done properly. Of course, done improperly, you can over-heat and actually burn carbon out of the steel and end up lower than when you started. Just try cutting the side before and after with a jewelers file to see if you did it right. If the file still cuts after hardening... it ain't. If this is a gun that will see heavy use, you would probably be better off getting someone here who does bone pack hardening to put your little parts in the crucible when they make up a pack. I wouldn't think it should be too costly.
