Glock finish issues ?

[481]

I picked up a nearly new gen4 G17 on via Armslist a few months ago, and noticed the finish looked weirdly different than any other Glock I'd owned. Comparing it to others, it was smoother, and very thin looking, and the color was difficult to describe, but it wasn't your basic black.
I did some research, and apparantly they stopped using Tennifer several years ago, supposedly due to environmental concerns, and this new,thinner finish is now used. I've read numerous complaints about it scratching and wearing through very easily, as well as rusting more easily, and most owners didn't sound very impressed.
My others G's are early gen3's, and I believe have tennifer finishes (yeah, I know it's a 'treatment', not a finish), with no complaints.
I called Glock HQ about dating a pistol with a serial number I couldn't find a manufacture date for, and asked about the Tenifer while i had him on the phone, and was told by a tech I spoke with that they stopped using it in early '11, but I've read credible reports from others that the date was a bit earlier, so who knows.

I'd heard much the same thing as you except that the quoted changeover occurred in mid- to late-2010. The 'new' process is apparently carbonitriding done in an ammonia atmosphere -the NH[sub]3[/sub] acts as a nitrogen donor which also aids in increasing surface hardness.

Which provision or provisions? You'll find it awful hard to cite anything from this "clean air-clean water act" of which you speak as no such joint act has ever existed.

(HINT: I admit that I'm playing a loaded game here because I tire of debunking this Internet myth every five or six months when it resurfaces again. As of yet, I have found no one with a working knowledge of either the technical or legal aspects of this topic who claims this is some 'banned' industrial process.)

It isn't a myth because the finish surfaces ARE different on older Glocks verses American made Glocks and even on my new Austrian made Glock.

I'm not a chemist nor affiliated with the EPA or any environmental groups so I cannot give you specifics related to the exact processes.

My 2 cents worth

Own 3 Glocks G27, Austrian 18yrs old, Glock 22,G3, Austrian, 3yrs. old and a G19, G4 Austrian, 2yrs. old. The finish on the G19 is a lighter gray-black tone. As far as care I shoot, holster and clean all 3 the same with no difference in wear or damage. Still love my 27 best, especially since I got the LW 357 sig barrel.

Anytime I think there's a scratch on a Glock slide, it turns out it's just metal residue from whatever it rubbed against because the Glock finish is so hard.

Besides, they're utilitarian pieces based on fulfilling a military contract. They look their best when they have a little 'character' after a few thousand rounds & holster presentations!

You're asking a bunch of Glockers if the finish is ok on the Glock. That's like asking a realtor if it's a good time to list your house

Um, posting a question on a related internet forum pretty much IS a form of "looking it up".
