CM9 cleaning - afterwards there are problems

[odn08]

So i've put around 400 rounds through this weapon by now. Last time i took it to the range it performed awesome, no jams, no issues. I've had it at home for 2 days now and finally got around to cleaning it today. After i put it back together, i slapped in a 6 round mag, hit the slide catch and boom, a nosedive. I've never seen that before. I tried it again, another nosedive. The rounds were totally pushed in and deformed. I racked it a couple times to lube it/smooth it out. Then hit the slide catch, and it chambered the round, however upon inspection, the round (hollow point) is deformed. The hollow point is pushed back into its cartridge. This is pissing me off. How can you clean a gun, and it ends up being worse than before? I dissasembled, reassembled a couple times to make sure it was put together right. It seems to be.

Now it will chamber rounds, but deform them as said earlier.

Kahr wants me to send it back, the tech rep was completely unhelpful, not giving any advice/or information saying he's never heard of this before (really??). this is turning into a major pain in the ass.

Anybody come across this issue?

Did you check the magazine? I had the same issue with my CW380. Flawless at range. Clean, lube, nosedive. It was a mag problem.

Exactly what I was thinking. If you took apart the mag spring make sure the spring is angled at the top the same direction as the follower. Oh, make sure the follower isn't damaged too.

I didn't touch the magazines at all. Been working flawlessly at the range. The only thing changed in the equation is the gun that i took apart, cleaned and minorly (small small amount) lubed with clp.

also i noticed before it was taken apart that the feed ramp was angled a little to the right upon inspection of the chamber, i though that weird but it worked great. After the dissasembly/cleanup/assembly, i noticed it straight up and down, neither angled to the right or left. Could this be a part of the problem?

Do you have another mag to try?

[codegeek]

Ah, the notorious nose dive issue. *sigh* CM9s seem to be more resistant to this phenomenon. Kahr is in denial about that and their broken follower issue. The follower mod solved this problem with my CW9. My CM9 doesn’t have this problem.

I used it on all three mags. Two 7's, 1 6. When i chamber a round again, it just keeps smashing that hollow point inside its expensive cartridge lol. ****** A.

With the slide open, insert a loaded mag slowly and see if the bullet is contacting the slide release and being pushed nose down.

I guess you could double check that the recoil springs are oriented correctly. Open end toward the muzzle. Beyond that you're going to need more help than I can offer. Linking to a picture might be helpful.

The first place to look is at the last thing that was done to the gun. You shot it. You field stripped it. You cleaned it. You reassembled it. My guess would be that you reassembled incorrectly. Did you read the manual? Did you watch the field strip video. Might be a good place to start.

thanks guys for your help. i'm gonna send it back to kahr, i'll let you know what they say.

I agree with this. It solved a couple of my problems. Make sure the point of the recoil spring on the guide did is pointed towards the barrel.
Good luck!

This is the exact problem I'm having with my new CM9. I cleaned mine before going to the range. Fired 125 rounds through two 6 round and one 7 round clips, no problems. Come home last night, took it apart, cleaned it, and when I went I went to rack it the bullet nose dived and the slide stuck back. I've tried all three mags. I took it apart again and now if I put just one or two bullets in a clip I can rack it and the slide doesn't stop at all. If I try to insert a full clip it nosedives. What did I do wrong? How can anyone trust this gun as a carry piece if its that sensitive or defective. I am really disappointed.

This is why I always put the old dirt back in after I give my PM9 a good cleaning.
