I'll be interested in seeing what the culprit is, when you get it figured out.
Help me diagnose and fix my EDC

It must be...I can't even find my ejector spring.

Well, based on the difference in length between the new and old springs I think it might have been past time for a replacement.

Sounds like a good excuse to buy another gun, seems to me....

You might be on to something there.

Update: with the replacement recoil spring the gun shot Remington 115 +P flawlessly but choked exactly the same way using regular pressure 124 grain Gold Dot. 4 out of 20 shots suffered exactly the same failure to eject with the empty case trapped longwise between the breech and top of the barrel hood. I’m at a loss to explain why it suddenly won’t eject ammo it used to handle flawlessly and yet function perfectly with everything else.
And of course I just ordered a case of 124 Gold Dot +P. I’m crossing my fingers it will work with the +P, since I was testing it with some of the regular pressure I happened to have. Function testing with premium defensive ammo gets expensive! It might actually end up being cheaper to just buy a new gun

Would change recoil spring for sure since you have shot it a lot over the years. I would also find a spring for shooting the +p or stop shooting +p.

Have you tried loading (1) round at a time in the mag and firing it?

Still sounds like the extractor to me; it's not holding the case looking enough for a solid tap against the ejector. Either the spring or the extractor itself could do this.
And, don't order a replacement spring; order replacement spring kits, compete with all of them. Always have at least one compete kit on hand for any social weapon.
So speed of the slide is affecting it now... change mag springs, extractor spring, Id probably order a new extractor just to compare your current one too.

I have another Kahr 9mm (budget model micro compact) that has basically been a spare gun. I completely stripped the slide and swapped every part with my P9. We'll see if that makes any difference.

Elkins45,
How did you make out replacing the different parts? Just interested in the outcome. I beleive you are looking at an extractor wear issue. Do you by any change ever single load a round in the chamber and send the slide home? Or do you always run your ammo through the magazine?

I won’t know until I get a chance to get back to the range next week. I always run it through the mag because single loading is suppposed to be hard on the extractor. A visible inspection of the extractor didn’t reveal any obvious problems, so I’m hopeful it’s just a weak spring. I ordered a full set of springs from Kahr under the assumption it certainly won’t hurt anything to replace them all.
A question... Have you ever timed yourself on Wilson's 5x5 drill? It pretty well broke me on +P on a Micro 9mm (Ruger EC9S). I'm thinking of going even farther down this path with 9mm "Chubbies" for practice and Micro HST for Carry. This from a guy that used to carry Federal 135 +P Tactical Bonded in the little guns.
I also found out I'm faster with a .45 Shield than a .40 but faster yet with a M&P M2.0 Compact in .40.
The reason I'm asking is you might reconsider if you actually need +P. That said you still need to replace the springs.

Well, the parts swap didn’t fix the issue. It didn’t jam as often but it still won’t go 30 rounds without one. I’m at a loss to explain why it only happens with Speer 124 grain Gold Dots, both +P or standard. I can understand a gun not feeding a particular bullet, but ejection failures with just one brand doesn’t make sense.
I guess I need to either choose a different gun or different carry ammo. That’s kind of a bummer considering I just spent $500 for a case of it.
I took a file to the ejector and gave it a slight angle in the hope it might send the cases more to the right rather than up. I figure I can’t hurt it at this point since the slide and barrel are the only original parts left on the top end.

Reprofiling the ejector angle and thoroughly scrubbing the breech face didn’t solve anything. It jammed on the 9th round in the last test so I just quit.
I used ammo from a different lot and that didn’t make a difference. I am well and truly stumped.

After the failed parts swap I gave it one last try with a brand new extractor, extractor spring, striker spring and plunger fresh from Kahr. I went through a full box of the problem ammo with no failures to eject. Visually I can’t see any defects with the old extractor, but as long as it’s working again I’m not going to look my gift horse in the mouth.
If it truly only malfunctions with Speer 124 Grain Gold Dots I would simply use the 115 or 147.
If you haven't actually tested with other Speer Rounds that use the same case it could be an issue with the extractor groove dimensions. In that case switch brands.
It's not like the 124 GD is the only effective 9mm.
Edit: I see you believe you have the issue solved. Good Luck!
