Hello, do we know what the slides finishes were over the years ?

For instance the 1st thru early 3rd gens had what appeared to be a flat black oxide finish.

At some point the frying pan finish appeared. I want to say 2009 but I could be wrong.

Thanks in advance.

I see this term- 'frying pan finish'- and I don't know what you guys mean. The original Glock finish was phosphate (parkerizing) over Tenifer. My very early 3rd generation G17 (September 1998 production) has this phosphate finish. I have a G17 made in October 2003 which has a slick, shiny finish to the slide. If that's what you mean by 'frying pan finish' it was used starting around 2002, I think.

My Gen 3s from 2004 have what you are referring to as frying pan finish. It almost looks like the inside of a Teflon pan and is very slick to the touch. My Gen 4s definitely do not

I have both a G19 and a G21 (Both Gen4) with the “frying pan finish” and I suppose it looks like a Teflon of sorts. It seems less black to me than other finishes. I kind of like it but I like my other Glocks just fine too.

Did Glock ever use an Ilaflon finish? I haven’t heard it mentioned in connection with SIG pistols recently, but for a time it was the finish to have according to its fans. It is also used on nonstick cookware.
