Kahr K9 and +P+ ammo?

[Gewehr98]

My early model Kahr K9 (law enforcement trade-in) was well-worn, with lots of missing finish on the frame and slide. But it was smooth, comfortable, and accurate, often times replacing my Caspian Officer's ACP as my carry gun.

Yesterday, I did the unthinkable. I ran three rounds of Federal Law Enforcement +P+ fodder through the little guy. On the third round, the extractor flew off to parts unknown, and the trigger return spring gave out. I'm attributing it to the hotter ammo and a weak (old) recoil spring, with higher slide velocities and the subsequent battering. As I read and reread my owner's manual, I don't see any mention of +P or +P+ loads being disallowed. So no more +P+ ammo for my K9, assuming that's the worst I did to the gun is break a couple small parts.

I THINK that the K-9 is supposed to be able to handle +P+ ammo.

You may want to e-mail Kahr to see what they have to say, and see about getting your gun factory reconditioned.

The K9 was origionally designed with a 24lb. recoil spring, and the factory now uses 18-20lb. springs because people complained that it was to hard to rack the slide. This was printed in a recent article in one of the gun magazines as supplied by Mr. Moon. Maybe one needs Wolff 23 lb. springs for such hot loads.

I have a very early K9 and a new P9. Both manuals only say that reloaded ammo will void warranty and that it (reloads) may exceed SAMMI or NATO pressures. If I'm not mistaken NATO is about the same or higher pressure than +P+ so your K9 should handle those hot loads. I'll attach what it says on the new manual of the P9.

Hope this helps.

I believe on the Kahr website and in an article I read "house of
Kahr" they said the K9 is rated for ANY factory ammo. The K40
isnt recommended for P+ or +P+. You should get ahold of Kahr
and have them fix your gun. Shoot well

The loads I currently carry are Georgia Arms 115gr +P+ GoldDots.
I have put about 300 rounds of these through my K9 without any indications of problems.
I believe the K9 as designed around the 115gr +P Cor-bon cartridge.

To date...

E-mailed Kahr Customer Service Saturday. Methinks they are on Thanksgiving break. So far, no response, but I'll simply wait until later next week and for 9mm, just shoot my 1918 DWM Luger this coming weekend. (No +P+ loads in her, though!)

FYI...I spoke with Kahr customer service this afternoon on an unrelated matter, but they were open for business...

I'm pretty sure Kahr recommends the recoil spring be changed every couple thousand rounds. Since this was a used pistol that may not have been done by the previous owner. The Kahr is definitely okay with any 9mm ammo. They have great customer service. Good luck. Incidentally ut83, I'm not aware of any +p or +p+ .40 caliber ammo. It is loaded pretty hot in its original configuration.
