What is Nitron, Bruniton(beretta), tenifer(Glock), HE(Hostile environment)finish(HK)?..Whats the diffs? Is it the same with different trade name? is one better than the other? How does it differ with Parkerizede and Anodized? or Electroless nickel?

Glock’s Old Tenifer was one of the toughest. Tennifer is actually not a finish at all, but a metallurgical process performed on the metal pistol surfaces. The metal is treated with a cyanide mixture bath to increase hardness and corrosion resistance. It is actually impregnated into the first few microns of the metal. The Tennifer treatment is colorless. Glock simply powder coated the slides black after the Tennifer process was complete. You can take a piece of sandpaper to your slide and remove all of the powder coat, leaving your slide a dull stainless color (which looks pretty cool) and the Tennifer properties will be left intact.

Diamond Like Coatings. Guns such as the S&W M&P series, SIG, FN, and some others are all using these as their finishes. There a couple different types of DLC and a few different ways to apply it, but each one has the same result…. a super hard, corrosion resistant and low friction coating that is very thin, and looks good. Hopes this helps.

So is Nitron like or similar to DLC? How will I know if my Glock has tenifer finish? Mine is Austrian made around 2004 manufacture..I also have a new Gen. 4 US made G17...

How about the Melonite finish SA uses on their carbon steel XD slides?

Only license names seperate Glocks "Tenifer" process from "Melonite" , which are licensed brand processes. The original German formulation for the "Tenifer" carbonitriding salt bath uses a 60% sodium cyanide and cyanate and 40% potassium cyanide and cyanate.... The EPA won't permit this specific process here in the US as the process has to be cyanide free here.

As far as DLC, Diamond Like Carbon or otherwise referred to as DLC or amorphous carbon coatings are unique in that they are the only group of low friction coatings that exhibit a high surface hardness and a low friction coefficient providing wear resistance which keeps the low friction coating at the wear interface where it is needed for a longer period of time. Although DLC coatings are not applied primarily for corrosion protection, they will provide improved corrosion protection from corrosive environments.
