G19, Gen 3, S/N TTL***, born on Aug 30, 2012, new style non dip MIM extractor

During the first 200 rounds I was getting about 5% back to face.

Swapped the extractor, firing pin safety, and spring load bearing assembly from a 2005 G17.

We then fired 350 rounds of Win White Box, Blazer aluminum and brass, and Federal Champions (100 of the 350 rounds and the lightest load). I, my wife, and a new shooter that had never shot a handgun before, shot the 19.

There were ZERO back to face.

During those 350 rounds I started reinstalling the original parts except for the original non dip extractor.

Today I reinstalled the original non dip extractor, and back to face started with about 5% of the 100 rounds I fired, mostly with Federal Champions (50 of the rounds fired today).

The new non dip extractor does show wear and mold marks. I don't shoot the G17 that much, so I'm just putting that extractor back in to the new G19. Just sharing.

Can you take a pics of the extractor? I'd like to see the mold marks compared to mine. I have a new 19 from 6/12 (USA made), non dipped extractor, with no mold marks...

Here you go. Non-dip MIM 2012, 300 rounds

 

[Buckshot Barry]

Cast, 2005, about 2,600 rounds total. 350 in the G19 and about 2,250 in the G17.

very interesting info. I especially like the pics of the cast vs. MIM ejectors you posted. Can the cast ejectors still be bought? I've read that you can buy the old style non-dip extractors, but are they MIM or cast?

I had an early 2010 production 17 gen 4 that had pretty decent ejection. Just for fun I installed a new non-dip extractor and a new Lone Wolf extractor in it. Ejection went to hell in a handbasket. I put the original dip extractor back in and everything was fine again.

I swapped out my extractor on my G19 gen 3 SN SDA*** The factory had a 2 stamped in it, and ordered one from Glockparts.com that didn't have any marks. This solved my 2 per mag BTF's.
I don't believe the RSA on the Gen 4's has anything to do with the ejection issues. This is a problem for gen 3's as well as gen 4's

Buckshot, you just taught me something! Thank you.

 

[19Glock19]

Thank you! As I suspected... Great pics...

Now knowing it was the non dip original extractor that was causing BTF, I took a very close look at it with a magnifying glass. There were 3 gouges on the top corner. There was no finish wear on the slide in that corresponding area. I used a ceramic sharpening stone to clean up the areas marked in red and to remove about 80% of the gouge marks.

I ran 100 rounds through the 19 today issue free. I shot it with both hands, right hand only and left hand only. No back to face. I think the original extractor was hanging on the slide. WHOOPEE!

Not all of the new non-dipped extractors come from the same mold. The one that came on my USA made G17 is marked "4". The ones I ordered from Glockparts.com are marked "1".

Let's remember, it's not the dip that's causing problems: that was just a way of distinguishing older cast extractors from the newer MIM ones. Now we have MIM extractors without the dip. It's entirely possible that some of them may be better than others. Some may fit certain guns better than others, which could get really confusing.

One of the ones marked "1" improved my G19 Gen4 tremendously.

Still seems as if either extractors or extractor cut in slide out of spec. ,boils down to something out of spec. SJ 40

Very interesting. Great photos. Thanks.

Here is the extractor after polishing. It's stamped with a "4"

That's very interesting. The factory original extractor in my Gen 4 G23 I bought new in the fall of 2010 has a MIM non-dipped #4 extractor. It works fantastic in that pistol.

Are there really two #4 extractors (9mm and 40), or is Glock now trying a 40 extractor in the 9s like some have had success with?

Buckshot,
Thanks for sharing and the attached images for clarity.

I agree that the "dip" as a result of the sintering process doesnt seem to have anything to do with the components performance.
Other than it being unsightly, and take away from the already decent clean lines of the slide.

I own all Gen3 Glocks, all mine are dipped.

I would like to shoot and test some non-dipped.

Do you know if this is a direct from factory purchase to obtain them?

I wish glock would stop messing around and go back to the original extractor and be done with all these problems.
