I knew Glock had been playing with different finishes the last couple of years and had heard rumors about them stopping using the actual Tenifer process and today I talked to Glock Inc. and they said that yes they have stopped using Tenifer and now use a similar although not exactly the same process.The CS rep could not tell me why or when they switched.

Does anyone know when Glock stopped using the actual Tenifer process?

Be aware that the metal treatment and the top coat are two different things. The Tenifer is underneath the top coat.

I just picked up a Gen 4 23. The improved grippiness of the lighter gray finish is really welcome.

GLOCK has indeed replaced the Tenifer process with a Nitrate (or Nitride) process. I think the transition took place at least a year ago. I learned of it in March 2012 at Armorer's Class.

Tennifer was a nitride process (ferric nitrocarborizing?) From what I heard, they switched to Melonite, which is a different name brand of ferric nitrocarborizing. Interestingly, they're both sold by the same company.

And yes, Glock puts a cosmetic top coat on top of this.

Tennifer uses cyanide as a medium and is either illegal to use in the U.S. or is strictly regulated (with obvious good reason). Melonite uses a different medium and is much more common here and is probably catching on in Europe.

Last new Glock I purchased was a G26 with a Manufacture date of July 2009. Slide finish is black and shiny, but the barrel looks more greyish. I had never even noticed it until reading about the different finishes and went and compared it with my older Glocks. Not real concerned about it as long it has the Tenifer under it and it sounds like I should have based on the manufacture date.

It's all about using safer chemicals in the process.
Basically the same metal treatment.

I was wondering that too. Got my g19 gen 3 (US not Austria) and noticed the duller finish of the slide compared to my brother's g19 gen3 mariner (Austria) which had a more glossy texture.

Anytime a proven process (Tennifer) is changed, people become nervous. The big question is whether the new treatment will be a durable and rust resistant as the old treatment. Time will tell.

Tenifer and Melonite are essentially the same process, both manufactured by HEF. Both develop a small amount of cyanide, along with the cyanates produced in the salt bath, which create a compound layer of nitride over a diffusion zone.

If they both are so similar and both have the same byproduct of cyanide, why did Glock switch?

Time has already told. Many reports of the new finish sucking for wear & more reports of glocks rusting in spots from normal holster wear & carry.
Many more reports then the older glocks before they started this new process.

At this time, I'm not convinced that they have. However, that said, both the Melonite and Tenifer processes develop small amounts of cyanide and cyanate in the nitriding salt bath as the process is performed. The cyanide and cyanate are important to the reactions that take place in the salt bath as the medium interacts with the surfaces of the ferritic materials being processed. The compound layer of nitride is formed, and a diffusion zone made up of carbon and nitrogen components is immediately beneath. Once the process cycle is completed, the parts are removed from the nitride bath and immersed in a second oxidizing salt bath that chemically destroys the cyanide and cyanate. Subsequent to immersion in the oxidizing bath, the parts are removed and cooled in water to near room temperature, followed by washing to remove salt residues.

With proper immersion of the parts in the oxidizing bath, cyanide and cyanate by-products are destroyed. Analyzing the wash water will reveal that free cyanide is not present. If both processes are performed correctly, Glock should not have significant concerns with cyanide being present on the parts they surface treat after they are FNC processed.

My direct familiarity with the salt bath FNC processes noted is limited to the Melonite, as we perform said process in our company, which is involved in commercial heat treating.

The USA "tennifer" is indeed different than the Austria "tennifer." It came down to the EPA which would not grant US the various certificates to use the same materials. Hence, US had to fine a like and very close product that met the EPA.

This was a detailed topic in an armorer's class nearly three years ago. Gwdex writes up some of what Glock USA dealt with, in dealing with the EPA.

It's not like Tenifer Glocks are the only pistols that are resistant to rust. If the new Glocks are experiencing spot rusting, then Glock picked the wrong thing to replace Tenifer (if not truly Melonite) or needs to get better at Melonite.

However, I would not care a hoot whether I got a gun finished properly with Tenifer or with Melonite.

OK.

A short Glock history lesson.

Glock used to make all kinds of products.

When Austria wanted a new army handgun, Gaston Glock decided to get into the gun business. Apparently there wasn't that much money in shower curtain rings and tampon applicators.

The first model pistol was called the model 1. It didn't work.
Models 2-16 had problems but model 17 was perfection.

Then came the other models.

Now, to address the question about finish:
The first finish process Glock used on the model 1 was called Ifer finish but it did not work well and he could see it needed improvement. He called the first process Oneifer.
Changing basic chemicals, he tried it again with Twoifer.
Perfection occurred with his tenth try when he used good old fashioned sugar as the active ingredient, He named it Tenifer.

When Glock opened his plant in the USA the Federal Government (the FDA) would not allow him to use the main active ingredient (sugar) in the process. After several years he finally reached Glock perfection once again by using Splenda in the process. It is now called Elevenifer. Nitride for short.


Don't even ask me how I know this, but Gaston's Mom vacations in Wythe County a couple times a year and I take her catfishing on Claytor Lake. :animlol:

I had already seen that thread, but found nothing real definitive. I even emailed the source(lynn freshly) listed on page two about where he got his info and he stated ...

"The information came from my boss at Glock Professional. It is my understanding now that 2007 was the start of the switch from Tennifer to Nitration."

Another Glock Inc.CS rep told me today that a total across the board of all calibers switch from Tenifer to the new process took place in mid 2011. I guess it's possible and/or likely there was earlier use of the new process, but I can't imagine it really being before 2010.He also said my July 2009 G26 with the Black Slide and Grey barrel would have Tenifer under both finishes.
Some may think this topic is redundant, useless or flat out annoying, but the Tenifer and it's performance history was a big selling point for me.The newer metal treatment although very similar and/or in the same general classification as Tenifer just doesn't seem like it's performing as well based on what I'm reading on various forums. I'm not sure if it's possible to get the real answer of when the switch was made or if/ how many early models where sent out with the newer metal treatment short getting the information from records directly from Austria.
I will personally stick to buying older Glocks(pre-2010)for now to be on the safe side.

the answer is no, the new treatment is not anywhere near as rust resistent. ive never rusted a tennifer glock. and within a month the new grey slide i bought with a march '12 test fire had specs of rust on it. i sent it to CCR and i havent had a problem since. the new finish is junk compared to the old one.

I found some interesting reading material on finishing.com

Like:
Gents, I can say with 100% certainty that the cyanide process that involves surface nitriding of metal is perfectly legal within the USA. I know this because I currently regulate 2 such processes right here in Springfield, Ohio. They both use a molten cyanide bath to introduce the nitrogen into the structure of the metal part being nitrided. Please see

Remember that Tenifer is not a Glock-only thing....and that it is very important how the process (Tenifer) is applied to material....wether it's a slide or a crankshaft.

Because Tenifer is not a Glock-only-thing, I doubt that they can mention the Tenifer being applied to Glock pistols on their website when they don't.....
I think Herr Tenifer won't be happy with that....

So I think they still use the Tenifer process, regardless what Glock CS reps say......or people at Armorers Courses.....I think that they only tell you things that they have heard from others they have heard it from others etc etc.....but no one really knows.

One thing I've learned is that about only half of what Glock inc. CS reps or any gun manufacturers CS for that matter tells you is correct. I learned that the hard way after making some purchases of guns that were not what customer service said they were.
You pose just about any somewhat difficult to answer question to 10 different sales reps at Glock Inc. and your likely to get 10 different answers. I had read on the internet (right here at Glock Talk)a couple of years ago that Glock was using a grey finish on all new production guns(both Gen 3 & 4) as well as the dipped extractor and I wanted neither. I called Glock Inc. and the CS rep assured me said that the grey finish was only on the Gen 4 models and that the Gen 3's were still the same with the slick black finish and old style extractor and would remain unchanged.I told him about the posts at Glocktalk and he dismissed it as internet rumors.
Based on that info, I ordered a new Gen 3 G17 from my dealer and when it arrived it had the grey finish. I rejected it and my dealer sent it back and from now on I double and triple check with customer service as well as hit the forums before ordering anything.
You call up S&W customer service and ask about Internal Lock failures and they'll tell you it's internet myth even though it's been confirmed to happen by Massad Ayoob,Grant Cunnigham and David Kenik to name a few who recommend avoiding it on a defense gun. Are those men buying into and spreading internet rumors? Most CSreos will just tell you want they want you to hear to make you buy their products. Buyer beware indeed.

Glock corporate likes to deride boards like this because they claim that the information is partially true.

The problem they continually face is that real world users are wringing out real world problems with their perfection. Glock had a history of quietly resolving problems before they became public. Then the internet flowered and boards such as this grew so that real users could post consistent issues they saw with the pistols. Corporate derides what is posted yet they are fearful of what we find, develop, and share. The reality is that in the years I have been going to armorer schools, the factory reps while smile and chuckle when someone mentions something they read on the internet. But that smile quickly fades when the end users agree it's an issue (Gen 3 light rail and cycling, G21 trigger bars, Gen 4 finish, Gen 4 RSAs, broken locking block pins, etc.).

If Glock were to grow up as a business entity, they would recognize that real world testing and data is posted here and "experiences," as a collection, speak to their line more than any CS or rep can ever hope for.

I enjoy Glock pistols like so many but I certainly won't dismiss something a poster writes when it is a legitimate problem, such as the quality in the "tennifer" processes.

Bustedknee - you, sir, are disturbed!!:thumbsup: I'll be saving that!

I, too, become concerned whenever Glock changes anything in their design, because almost every design change has caused a problem that required a subsequent correction. I can't help but believe that there are certain "known-good" serial number ranges for Glock pistols. I try to confine my purchases to older guns within certain S/N ranges. None of them came after the "shiny" slide finish characterized by "Fxx" through "Lxx". I avoid anything in the "Exx" range due to the possibility of the frame requiring an "upgrade".

We DO know one thing for certain. During one very significant period of time in Glock history (i.e. 1991 - 2010), almost no-one complained about Glock's metal finish. It became the standard against which all service weapon finishes were compared. It contributed to the sale of A LOT of guns to police agencies, and resulted in guns so durable that they could actually be refurbished and sold again through the "factory refurbished" program. Now, by contrast, we are starting to see and hear complaints about Glock slides developing spot rust. So, we can conclude that SOMETHING has changed. And, not for the better.

Corrosion resistance is part of the "simplicity" equation that made Glock#1. If they lose that advantage, S&W now (finally) has a competitive product that could put a serious dent in Glock's market (notice I said "competitive", not superior). Glock needs to not mess with their own "perfection".

I have had rust on my G19 made in Oct 2011. I have always used hot water when cleaning and noticed some rust on the slide in the extractor groove. The extractor was rusted as well. I have always used the same process for cleaning my Glocks, and this is the only one that has rusted. The finish is the dull color compared to all of my other Glocks. I live in a very dry climate and have never had to worry about rust.

+1 to this Ridder. As mentioned previously, HEF USA distributes the ferritic nitrocarburizing salt, additive and oxidizing salt for the Melonite process we use. Tenifer is the European equivalent to the Melonite process. The EPA regulates the discharge of free cyanide into the environment. The Melonite process, when operated correctly, destroys free cyanide in the oxidizing bath before the parts are washed in water to remove salt residue.

From TeamGlock@glock.us

Glock discontinued the TeniferŪ heat treatment mid 2011, and is now using a gas nitriding process. Same end result using a different process. Unfortunately, we don’t have an answer for you as to whether it was a gradual phase out but we are assuming it was done at the same time.

Best regards,
Emma

I then asked a follow up question to that email and got the following answer...

The TeniferŪ heat treating process ended sometime in 2009, but the slide finish had no bearing on which process had been done.

I am new to Glocks, I picked up my first in 2011 and now have two, born in 2010 and 2011. I have no experience with the Tenifer-treated Glocks or the black shiny finish. But, my grey-finished non-Tenifer-treated Glocks are by far the best wearing pistols I have ever owned. I have never had any trouble with finish wear or metal wear in either my Gen 4 G23 or my Gen 3 G24. As far as I can tell they are built like tanks and will take all of the abuse I can give them.

However, I tend to treat my firearms very nicely (I am not trying to imply anyone else in this thread isn't). I definitely use them, but I keep them clean and maintained.

I am not trying to say that newer Glocks are superior. I am just passing along my experiences with my Glocks. If older Glocks are even better, all I have to say is, "WOW!"

In the last armor's class I attended, we were told to wipe down the slide with a light coat of oil. I just wonder what happened, remember the, "you only need oil in these spots, not too much."

I can attest to the fact that our newer Gen 3, G23, pistols are showing signs of rust if not cleaned at regular intervals. My Gen 2 G19 has never showded any sign of rust, nor has my Gen 2, G23s.

I understand the EPA guidelines, but the new process isn't nearly as resistant to rust as the old one was.

My wife's G19 has a test fire date of 2/09 and my G30SF has a date of 1/09. Both have worked great. Unlike what was mentioned earlier I've never had to wipe down the slides with oil. I just wipe the dust off and solvent for the powder residue.

I really like the new matte gray finish. At first I didn't, but it quickly grew on me and now I wish all my G's had the gray finish.

I have all the generations except for the first. My gen 4 27 didn't have any rust issues at all. But I sent it to failzero anyway bc I was bored. I can say that the nickel boron finish is freakin awesome durability wise

Is that finish very expensive? They certainly look nice. I'd like to find an excellent semi-gloss black finish. I'm thinking about Duracoat.

I've noticed that my early Gen 3's held up a heck of a lot better than my Gen 4.

I think the new gen 4's suck compared to the earlier years. I have an early edition of a 27 and 23, the finish has held up great. I have a gen 4 35 thats a little bit over a year old that has the finish worn and 2 small rust spots. I also have a new 35 I got 2 months ago and after less than 12 draws from a kydex holster has the finish wearing off at the front. I never had a problem with the older glocks. I am dissapointed in the new finish. I will only get older glocks, no more new ones for me.

Sounds similar to the difference in German Sig's with Ilafon finish compared to the US Sig's with Nitrite. I've tried to avoid US made Sig's for many reasons including the finish, all of mine are German except one. This makes me sorry I sold my old Gen 2 Glock 22 a few years ago, but it was just too large for my hands. I ordered a Gen 4 since the new backstraps do help, I will have to keep it well oiled it seems.

OK.

A short Glock history lesson.

Glock used to make all kinds of products.

When Austria wanted a new army handgun, Gaston Glock decided to get into the gun business. Apparently there wasn't that much money in shower curtain rings and tampon applicators.

The first model pistol was called the model 1. It didn't work.
Models 2-16 had problems but model 17 was perfection.

Then came the other models.

Don't even ask me how I know this, but Gaston's Mom vacations in Wythe County a couple times a year and I take her catfishing on Claytor Lake. :animlol:

You failed to mention an important detail. The Glock SEVEN model was fabulously successful, but fell into the wrong hands and was therefore banned by the US government after that notorious "airport incident". Gaston was so despondent over this imperious government action that it took him another ten design variants to come up with a commercially viable product. That despondency would also eventually destroy his first marriage.

I have a Gen 3 G23. I keep the slide wiped down with CLP, and I lightly dry off the excess. When I take it out of the holster, it has dry, white lookng streaks on the slide. The only way I've found to get rid of the white or gray streaks or spots, is to put CLP (or Remoil) on it again. No rust so far. If I don't find something better and more affordable, I'm going to have my G23 done in Duracoat, black semi-gloss.

Yeah, they are nice. Just glad that all of mine were manufactured prior to the 2010-2011 cut-off period for Tenifer.

Gen 3 is quality, but Gen TWO was the true golden age of Glockdom. Western civilization began its long slide to oblivion when Gaston put finger grooves on the frames!

The USA "tennifer" is indeed different than the Austria "tennifer." It came down to the EPA which would not grant US the various certificates to use the same materials. Hence, US had to fine a like and very close product that met the EPA.

This was a detailed topic in an armorer's class nearly three years ago. Gwdex writes up some of what Glock USA dealt with, in dealing with the EPA.

Just one more reason (the EPA) to dislike that no good piece of garbage, Nixon.

Sorry for the extremely late reply. I've been away for a bit. No the failzero treatment costs 200 for slide and barrel. Leo get a discount but I can't remember how much. My 27 rides iwb on duty in humid Baltimire. Still looks brand new. Had my p2000sk, xds, and am in the process of sending in my new gen 4 23. 10 day turnaround. Can't beat it
