The .40 claw is angled rearward by 5 degrees to help raise the case mouth of the larger .40 casing up higher before it starts to exit the ejection port, the top of the claw is set a little closer to the breech face.
Some people have been able to drop a .40 extractor right into their 9mm slides and it fixed the ejection problem, however one person on this forum had to file down the top of the claw slightly to allow the 9mm case rim to slide under the claw properly. Once he did, it worked and fixed the ejection problem, but this lends to the idea that there is variation in how the cut-out in the slide for the extractor is placed.
The 40 non LCI extractor in my gen 3 19 holds a 9mm case to the breechface in the same manner as my gen 2.5 26 with non LCI extractor and gen 3 17 with non dip LCI extractor. The dip LCI, non dip LCI, cast non LCI, and Apex extractor all do not hold the case to the breechface well at all. If the 40 cal extractor doesn't work, I think my only option is to get a lone wolf or caspian slide or get rid of the gun.
The 30274 ejection stopped brass to the face, but I've had one horizontal stovepipe and one phase 3 malfunction in 500 rounds. Some folks with erratic ejection say they have not had a stoppage, but it is just a matter of time.
