Recoil Assembly came apart

[dimden]

Got back from the range today and was cleaning the CM9 when I took the recoil assembly out to remove the barrel the guide rod was unscrewed from the tube that the outer spring goes on. I looked at pictures and there appears to be a threaded section at the end of the tube which goes into the hole under the barrel (that part is now missing). Has anyone else had theirs come apart?

[Thunder71]

Never.

That's a new one for me...

[Bawanna]

If it's what I think your talking about it happens now and then. Theres a round nut like cap on the end that retains the inner spring. Some don't get locktited good enough and the nut flies off never to be seen again.
some have made their own new nut with a lot of filing and shaping.

I'd call or email Kahr and tell them what happened. They most likely will just send you a new assembly. You can save the outer spring for a replacement in a couple thousand rounds. I check mine periodically just to make sure it's not working loose. I just check finger tight, don't want to tighten or loosen it and break the locktite. It seems they are good and never fall off or they fall off pretty early in the game.

Almost. Caught it in time to apply a little Loc-Tite and have not had a problem since. There is a thread here somewhere in which the poster made a replacement round nut from a hardware store replacement. But, if you call Kahr, they will cheerfully send you a new one at no cost. Getting a new one from Kahr is definitely the way to go, IMNSHO. :)

Thanks, I'll call Kahr tomorrow. I just looked on their site for an support email address and couldn't find one. This is what it looks like with the gun assembled.

Good picture. I have an email address for one of the two CS representatives: jay.dandrea@kahr.com

If you send Jay the picture, I am confident he will respond quickly and helpfully. :)

Edited to add: I see that Mr. Thunder71 responded as I was typing. His address should work just as well, maybe better. As I recall, it was a response to an email sent to the general address that resulted in my having Jay's address. Best of luck either way. :)

Thanks Guys! This site is the best! I just fired off an email with the pic.

[CJB]

GREAT picture....

[OldLincoln]

^^^ Yeah DimDen, I'd say from the looks of that pic you're just plain screwed! :)

[340pd]

I would say you are UNSCREWED.

[jocko]

sometimes with picutres, no explanationis ever needed even.

very nice photos..

[dimden]

I like the idea of being unscrewed! It's better than having a screw loose. Kahr sent me an email today saying they would ship me a new one. I went back to the range today to see if I could find it but no dice. Anyway it was an excuse to go shooting again (life is good).

Has anyone else had theirs come apart?My PM9 lost the shaped nut at the range and Kahr sent one free First Class Mail

It's not hard to file a nut down to replace the nut on the recoil assembly, if you want a spare. Here's my post:

It's really easy and can be done in about 10 minutes using a drill as I did.

Wow thanks! I was thinking about getting some steel dowel rod about the right diameter to drill and tap as a stop gap measure waiting for the new recoil assembly. However if a 6-32 nut fits I don't mind grinding it down to fit. I think I'll make a couple of extra's too; nice write up and pics.:D

[dimden]

Back in Bid Ness! I couldn't wait for the recoil assembly from Kahr; had to get the CM9 running again. I made three at one time using my drill and a bench grinder. Oh yeah, it took about 20 seconds with both the drill and grinder wheel running; I had to touch it to see how smooth it was. Bad idea, as I now have a blister on my finger; that dam thing was hot!

[JFootin]

Did you locktite it?

[skiflydive]

Wondering if using brake cleaner to clean your slide and parts loosens up the Locktite. Lots of people use it and it works great but I never thought about it's possible effect on Locktite.

[dimden]

Yes, I used red loctite after decreasing it with brake cleaner. I do use the brake cleaner (non-chlorinated) to clean the gun, but I can only remember using it once on the recoil assembly.

[wyntrout]

Very good! Mass production. Did you use stainless steel nuts, though?

Wynn:)

[TucsonMTB]

Not bad. Stainless or not shouldn't be an issue, given that it stays lubricated pretty well. However, you might want to bevel the back edge, similarly to the way the original was shaped. Otherwise, it may hang up on the front of the slide.

That said, if it does not hang up cycling the slide by hand, you are probably good to go. Congratulations! :)

[dimden]

Thanks, I did use stainless nuts and a digital caliper to measure. I made sure they were about 30 thousandths smaller than the tube that the main spring goes on, so I don't think they will hang up. I looked at Thunder71 write up to figure out how to do it...Kudos.
