The Glock Slide Finish

What you see is not the old tennifer or new metal hardening process. It is the black phosphate coating. Tennifer and it's new EPA approved replacement is impregnated into the steel and is colorless. The black finish is applied on top of it, and does not effect the corrosion resistance of the slide, which still has a Rockwell harness of around 68--much harder than stainless steel, which I think is around 54.

Final slide finishes have varied over the years, and I cannot explain that. I've always liked the flat black of the 90's best.

My 2012 G23 has that finish, not a mark on it after a year of carry.

That's why I love it, no marks at all after all the beating!

Sticky needed for sure.

But yeah, the dull black coating of the 90's I liked best. The most recent coating seems the closest they've come to that in a while.

The glossy black I hated. Found it to be too slick in certain scenarios.

I will give you that about it being a little slick at times, but man that finish is tough

The new slide finish is not a kind of phosphate finish. Since Glock began to use plasma gas nitriding surface treatment instead of salt bath ferritic nitrocarburization ( Tenifer ), no additional surface treatment or finish is applied on the slides after the surface treatment process. At a certain degree of heat during the plasma gas nitriding process, the metal itself gets oxidised and darkened. The new Glock slides are surface hardened and oxidised at just one step, instead of two steps of surface treatment and epoxy baked on finish that was used to be...This is why the dark dull black colored surface of the newer slides get scracthed easily.

By the way, while Glock claims that the newer surface treatment is much more rust resistant, or at least as rust resistant as it was used to be, it is exactly false, the new slides get rusted easily.

I do realy want the two steps of surface treatment and baked on finish of the Glock back....

Best.

This^^^ exactly why my avatar pics are my only gen 4 guns that have been nickel boron coated. My older gen 3's look fantastic after carrying everyday.

I am all confused about finishes now. My older glocks have the dull flat finish "Tenifer treated", and my new have the Teflon looking finish (not flat, not easy to scratch). My barrels after 3k rounds hardly show any sign of chatter or slide. So little that you would have to hold and inspect it, it wouldn't show in a picture. I really like the Teflon finish minus the slickness at time. I can scratch my finger nail in the side until I have no finger nail, there wouldn't be a mark on it.

They were all tennifer treated until recently. The tennifer was under the black. The older Teflon finish was the best IMO. But some like the dull flat. Matter of personal opinion.

Whatever dull gray finish is on my 10 gen 4 G22 is a POS. Thing looks horrible, nicks, scratches, worn spots. My 06 G17 & 09 G27 looks brand new. My newer 12 gen 4 G22 has held up much better though. It's that shiny finish.

Having owned them (all Austrian and purchased NIB) since the early 90's, and early to mid 2000's I have seen a variety of factory finishes.

First model 19 from 1991 had a very rough, almost "parkerized" finsh. It sucked up CLP like a sponge, showed all minor scratches and holster wear BUT 1000% resistant to corrosion.

Next came a Gen 2 23 (maybe 1998-99) with more of a Beretta "Bruniton" feel and look. Pretty slick but sometimes looked unevenly applied (depending on the angle/lighting).

Mid 2005 model 21 that was not as shiny but has showed zero scratches after MANY presentations.

Ok I don't guess the new flat finish has made it my way yet. I was in a LGS today and they where all still the Teflon glossy finish (which I really like).

My vote is for the Teflon like finish (btw I know it has nothing to do with Teflon, it is just the easiest way to describe it)

I was issued a new G22 Gen4 about a year and a half ago. It has a semi shiny finish. It looks like its finely pitted underneath, but smooth. Awful finish. It's got bare steel showing on several places.

I have a 13 year old G35 that was previous issue with the older grey parkerized looking finish that held up remarkably for the 10 plus years I carried it.

I agree. I had a 4th gen G34 start to rust. First I'd ever experienced that with a Glock. The gun was oiled and stored in a foam-lined case (a huge no-no for most guns, but I figured that this Glock, like all the others I've owned, was almost impervious to rust). Lo and behold, in a couple of weeks, the slide had several small orange rust spots, and numerous dark splotches indicating the beginning of corrosion under parkerizing.

The Teflon (or epoxy, whatever it was) certainly looked the best and was most durable. Functionally, however, I found the rough oxide on the early guns to be the best, as it added extra purchase when grasping the slide.

All my Glocks are gen3 or earlier.'08.
