Glock slides no longer tenifer coated ?

[BigSlick]

I see John made reference to Glock having new slides that aren't tenifer coated in the Tupperware Repair section http://www.glockpost.com/forums/showthread.php?t=10320

I've been out of touch for a while, and didn't know about the change.

What are the new slides finished with ?

i dont recall what they are going to be coating the slide with now, but from what i understand the tenifer coating process is illegal in the USA. something about the environment blah blah blah.

I heard some mention of this about a year ago, for replacement slides, but wasn't sure if it was gun show speculation or the coming thing.

I know a lot of the aftermarket slides are all stainless or coated carbon steel, I didn't realize Glock had gone to using a replacement slide without the tenifer coating.

I agree with John, if I were to get a replacement slide I would want the tenifer coating too.

Maybe Glock is keeping it low profile, or using a third party slide for replacements as a way to save a few bucks. :dunno:

The process to teniferize (I just made that up) is illegal here in the US. So maybe they give you a slide made here without the tenifer?

A phone call to Glock in Smyrna might be in order.

Glocks Front page of their Website still Claims Tenifer.

far as I know Tenifer is just a surface hardening process, not a coating. Kind of like case hardening but a different chemical process.

S&W does basically the same thing and calls it Melanite right here in the states I believe. The treatment process is a big plus for the GLOCK line, It'd be hard for me accept they would just abandon it.
Maybe they're going to a stainless slide or something.

Just because its on the Internet (or Wikipedia for that matter)
Dont mean its True.

Here is what I found...

The stuff I was hearing regarded the process being the issue. Having to do with (at least) local regulations.

I guess I could live with a stainless or hard chrome with a black phosphate over it.

Just about anything except those stupid looking flames on some of the third party slides.

Don't mind me, I'm old school, I think some things gun related shouldn't change.

i wouldnt want anything but tenifer, it's properties are amazing i think. i've never seen any metal finish that is as durable or as corrosion resistant

[ISUSteve]

I think it has to do with cyanide.

My new G-19 I got for Mum has the newer, flat finish. I hear it's practicaly the same as Tenifer, but done Stateside. I do like the smoother finish of the previous Glocks.

For the record: It's not illegal to use Tenifer in the United States; it's currently being done by other companies.

Buddy of mine put in an order for a G30SF this morning. I will check on it when it gets here in a week or so.

I think the issue is the way Glock does it in Austria which is illegal. There are other ways that provide the same end, which are legal.

[FireCop203]

Y'all quit saying stuff about Glocks is illegal. You keep it up and theres going to be a recall on every Glock ever made.

The flat finish has nothing to do with whether the slide's Tenifered. It is. The finish is just that, a finish. :)

yeah, I remember my 1st G-22 had the same flat finnish. Still worked fine for a factory refurbished jobber.

The Tennifer coating is Glock's name for a process very similar to Nitriding.
The exact process is slightly different, & can't be done here due to EPA regs; It does involve cyanide & the disposal requirements make it cost-prohibitive.
It is the same process that Porsche uses on it's crankshafts.....can't do those here either.
Interesting enough, the color of Tennifer varies from stainless steel matte silver to a rich honey gold.
I've removed the black oxide from many Glock slides in a glass bead cabinet & found a wide variety of colors in the range above.....never know what color it will end up till you blast it. But the color has no effect on the hardness, it's just slight differences in the metalurgy of the slide. All still within tolerance, just different.

Tenifer is merely a trademark name, and is identical to Melonite. They are the same process, owned and licensed by the same company. It's perfectly legal to use in the United States, assuming one follows the applicable laws.
