K9 Erratic Ejection Problem

[batman16]

I just picked up a 2006 era K9 second hand. Previous owner claimed it only had 400 rounds through it. I've shot 200 rounds through it and I'm getting very erratic ejection patterns. 50-60% of the ejections are normal (3-5 o'clock) but the rest are all over the place - vertical, left shoulder, right shoulder, forehead, top of head, etc. Tried different shooter and ammo with same results. Gun seems to function fine and very accurate. Spring "feels"/looks normal for round count and extractor looks fine. Most Expended Cases are dented at the top but I believe that is normal.





I'm just looking for advice on how to fix this issue - more of a nuisance than anything but none of my other guns have such erratic patterns. I'm wondering if there is a larger problem brewing. What could possibly cause such erratic ejections?





I could order new spring, extractor for about $30 and see if that helps. I called Kahr - they were no help but did offer to look at it. I just don't want to pay the $90 for shipping if I can fix myself.





Any help would be appreciated - thx!

Probably should have titled this differently...

Two more questions if anyone has time. I was looking at the ejector and comparing it to my PM9. I noticed two things different. First, the K9s ejector is straight and blunt at the end while the PM9s slopes down towards the tip. Probably just the way it was designed. Secondly, with the slide off, the K9s ejector is a little loose. It moves just a little while the PM9s ejector is rock solid. Any idea if the ejector being slightly loose could cause a problem? I would appreciate it if some could break down their K9 and take a look...

the k9 should not be loose & sounds to me like that is the root of your problems, I checked my e9 (same frame as the k9) and it is rock solid.

I tried to take a picture, but between the poor lighting, my shakey hands & the fact that I have to get ready for work - they didn't turn out, I will try to get some better ones tomorrow.

Thanks! I'm starting to think that is my issue also.

My partial dyslexia made me misread the topic of this thread and I thought it was another weird spam post from China.

I thought your dog was having erratic erection problems.

Ejector on my late 90's K9 has a little up/down wobble to the point I have to push it down to get the slide toslilde over it. But never had an ejection issue. Check the extractor for a chip or gummed up. It it is not holding the case properly, it may not be holding it correctly for the ejector to kick it out as designed.

K9 Erratic Ejection Problem

Thx for the reply. I guess it just depends. I have heard from some that the ejector has no movement and others have a little play with no issues. I'm not sure - maybe I will give Kahr another call...

I'm also noticing a lot of brass dings on the left side of slide ejection port. Any ideas on that?

K9 Erratic Ejection Problem

OK - the more I check out the gun and research problems I'm lost on what could be the problem. I do not have enough knowledge to understand what is happening during the extraction process. I need an expert to weigh in on this. So far:
1. Erratic ejection 50% of the time
2. Cases dented or crimped at mouth - obviously hitting something. Not all cases but most. I have not correlated damaged cases to erratic ejection yet.
3. Many brass dings on left side of slide at ejection port. Looks like brass is bouncing off slide.
4. Ejector has a little play in it but based on other posts probably not a problem

Any ideas? I'm concerned about all the bent case mouths and dings on left slide.

Based on my experience with other guns...

- a rounded / slanted tip on an ejector means the ejection pattern will be erratic depending on where the case hits the ejector.
Square ended ejectors usually give a consistent pattern.

- the dented case mouths mean that the case is still in the breech area as the slide comes forward, the case mouth dent comes from hitting the rear of the barrel or slide. So, the ejector is not getting the case out of the breech area fast enough.

- some wiggle in the ejector is OK as long as it is square ended and stays in the same place while in use.

here are a few pictures of what my ejector looks like.

Thx - looks pretty much the same except mine is not coated black.

It's normal for kahrs to have a "D" shaped case upon ejection. It says so in the manual. I have had two K40's and they both have done it regularly. The ejector pulls the case, it bounces back forward and hits the front of the ejection port. Then it flies wherever it it wants, in back of you, a few consistently to the side, and then some forwards. It sucks that it happens but it's normal. It's one of the main reasons why the K40 is not my favorite gun. Everything about it is perfect except the erratic ejection because I collect all my brass and reload it. It takes way longer to track down all the pieces because they aren't consistent. The D shape brass doesn't really matter but some cases get crushed by the reloader because they aren't round like normal spent cases.

Thanks for all the tips and advice - I did not realize the D shaped case was mentioned in Kahr manuals. I guess I just got lucky with my PM9. I just wish the K9 ejected cases were not so erratic. Everything else about the gun is awesome!
