Failure to feed. extractor tension.

[Jim K]

What is factory specification for extractor tension?

KP9093A. Measured 64 OZ. Shortened rear extractor spring PIN 0.045" .

Extractor tension is now 32Oz. and pistol feeds perfectly. no problems after 500 + rounds.

I am not happy with the experience I had with my Kahr pistol.

Quote from Kahr service:


Some info they just do not want us to give out. Please let me know if there is anything else that I can help you out with.

They dont give out tech info like that because they dont want people modifying their pistols, it voids your warranty. Kahr is pretty strict on stuff like that.

would you want to shorten the rear extractor spring pin??????? Un less you know more than the designers at kahr, it makes no sense to me..

Jocko,

I shortened the rear extractor spring PIN, part number 027P9 in order to lower the exractor tension. The extractor tension was way too high on my P9 which caused a failure to feed problem.

A new pin costs $1.10 purchased from Kahr. This is not a modification, it is a REPAIR. I make no claim to know better than someone who "designed" the pistol. I merely ask what the engineers had in mind when they put this idea to ink. My question remains; what is the factory specification for extractor tension of my P9 pistol? I would like to know if this is a quality issue or an engineering issue.

Don't tell me about that "break-in" BS. A $700 pistol should be 100 % reliable right out of the box. Do you have to drive a new car 10,000 miles to make sure the wheels don't fall off?

Now for the range report. I have fired my Kahr P9 over 1000 rounds since lowering the extractor tension. No FTF's, no extraction problems. It is NOW 100% reliable.

I could not care less about warranty. I would rather have a reliable weapon.

Again, what is the factory specification for extractor tension? Is there one?

Jim K..
I'm just curious.
How are you measuring your extractor tension?

I've seen gunsmiths use an extractor tension gauge and
a trigger pull scale. (I think)

[jocko]

Jim K, u do seem to have all the answers, you should send your resume to Kahr??

[Jim K]

Jocko,

I don't have all the answers, only one question.

AGAIN, what is the factory specification for extractor tension of my P9 pistol?

Please read the thread. I know what works. I just want to know what Kahr specifies.

Does Kahr have any answers at all? They seem to be nice people, but they don't seem able to answer one small question.

Regards

500KV,

Extractor tension was measured with a
Weigand Extractor Tension Gauge Set, Brownells part number: 957-101-000
and a Lyman Trigger Pull Gauge.

Takes all the guess work out of the problem.

O.K. Thanks.
That method I'd seen probably isn't too accurate.

(ETA) Well after a second look, I guess that's the method I saw them using.

I was ready to saw my Kahr in half. Now I love it.
