Question for Jocko and all enlightened ones!

[Bpc9876]

Hey all, I lurk here occasionally and have a parts question regarding my CM9. I was at Kahr's website to purchase some spare parts such as trigger bar, RSA, slide stop pin, striker,extractor spring etc. My question is can I purchase a PM9 slide stop and switch it out for the MIM'ed slide stop of the CM9? I called Kahr the tech was not very knowledgeable and gave me a standard canned response. I am curious to see what all you think? I don't see how it would potentially hurt to try and fit it, unless others know for sure. Thanks to everyone!

You lost me at "for sure". But I think you can use the PM9 slide stop.

[Bpc9876]

Pardon me, I meant to say unless others know for sure the slide stop won't work or fit, then I will not waste my money. Thanks for the reply.

[b4uqzme]

I'm pretty sure I've read here before that others have made the swap. It makes sense as the frames are the same. Just the slide details differ. And those are just cosmetic details.

Many people don't see any disadvantage to the MIM part. I haven't read about any of them failing.

[CJB]

The parts are interchangable.

Know this: The slide stop on the PM is not milled (or at least fully milled). Instead its a MIM stop on a very hard, ground pin. Its a two piece arrangement, the benefit of which is the harder than billy-snot pin.

The CM has a one piece slide stop, made with the metal injection molding process - just like Colt and Ruger, and Smith & Wesson have done for years. Nothing wrong with 'em. And yes, Ruger does in house MIM as well as thier trademark IC process. Smaller intricate parts do better with MIM.

There's no benefit for changing the parts. You just about never hear of a failure in the MIM part.

[Bpc9876]

Thank you very much for the replies! I was simply going to order one to throw in the spare parts stash bin and figured I would probably be better off with the PM style of stop. I have never had issues with the MIM-ed piece I have now; other than my straight thumbs always ride on it when shooting which is naturally my fault. Thanks for your expertise.

If I may ask you guys whom are intimately familiar with the design which springs and items should I have on hand for backups as they do not sell a kit for the CM as they do for the CW? Other than spare RSA? Thanks again.

[Alfonse]

My suggestion would be to just get a whole backup pistol. With recent prices, they don't cost much more than some pieces.

[CJB]

If I was inclined to make up a spares list -

Wolff recoil spring(s)
Wolff striker spring

Then from Kahr a slide stop spring, screw and washer.

Thats it.

Slide stops, ejectors, strikers, striker spring guides, trigger bars, triggers ... almost never an issue. Just read up all over the forum and you'll see. Occasionally an extractor issue. You can break followers if your barrel is smacking them, so check that and fix the cause, instead of getting spares.

Really, the Kahrs are pretty reliable. The only fubar folks make is fat fingering the slide stop into place and bending the spring. And the recoil and striker springs do wear with use.

Your first mistake was calling on Jocko. You second mistake would be trying to decipher his reply. Other than that you came to the right place for answers. :)

READ THE FOLLOWING POSTS UR ASK THE QUESTION ON AND THEIR ANSWERS ARE RIGHT ON TARGET. cjb IS DEAD RIGHT TO. lEAVE THE mim PART ALONG. NO HARM NO FOUL in that part

u can g to wolffs gunsprings site and just order the outter recoil spring that is listed under the PM listing and it is the same. They offer two weights, even, factory and a tad heavier.

I would also while there order their 5# drop in striker spring and a few of their 5% more strength magazine springs tha tthey list also. These are parts that you will periodically need to replace as normal maintenance. I would pass on the slide stop lever, but its ur money. Sometimes it is very hard to over come bad PR given to a process once it hits the internet..

[muggsy]

Jocko, I take back almost everything bad that I've ever said about you. You are right on the money on this one. Now don't let that comment go to your head. It's big enough already. :)

which head are u referring to???? Just sayin:amflag:

[b4uqzme]

^^^^ THAT should be obvious. :rolleyes:

[wyntrout]

A couple of more parts to think about are the extractor and the pins and spring. If you ever have an overpressure event, that extractor is likely to disappear. It's very hard to find... been there done that 3 times... found ONE extractor, and that was at an indoor range... with a very littered range floor.

Along the same line, the screw that holds the side plate could be lost, too.

I bought a case of remanufactured 9mm ammo about 15 years ago and shot 850 rounds before having case ruptures at the base near the rim... with a specific brand of brass. I finally had to destroy the rounds left... only a few of those, because they did rupture and even blew the extractor out of my K9.

Another thing is the nut on the front of the recoil guide rod. Get a spare recoil assembly or smooth a nut down to fit the slide opening... #6 hex nuts... #6-32 in stainless steel and use a 5/16" wrench for this nut:

Then there is the magazine follower/spring... on sale for the magazine kit at Kahr.com $9.99 for the follower and the spring in a kit.

I carry a lot of this stuff in a bag in my range box so that I can repair my pistol and keep shooting, or be able to continue to carry the one I started with. That includes the proper Torx screwdriver bits, numbers 5 & 6.

[jocko]

I would also have on hand two extra magazine followers. Justy sayin

[Bawanna]

You guys keep a veritable junk yard of parts on hand.

I got nothing. Confidence.

[jocko]

whats veritable" mean. Just sayin.

[Rubb]

whats veritable" mean. Just sayin.



Fancy word for "real" and because I keep nothing on hand but spare recoil springs...I too feel buoyant :)

[wyntrout]

There might be a shortage... or a breakdown... in EVERYTHING! :eek:

:behindsofa:

Wynn:)

PS: I also keep a lot of fiddly bits for my Glocks... in case I break or lose something while cleaning!:eek:

[Rubb]

There might be a shortage... or a breakdown... in EVERYTHING!




Good point and a good reason to have 2 :)

[Bawanna]

Or 10 or 25. I can have 1 or 2 break and still not be nekkid.

[Rubb]

Or 10 or 25. I can have 1 or 2 break and still not be nekkid.


trudat, but I find it tuff to conceal 10 ;)

[wyntrout]

I like choices... why I have 5 polymer Kahrs... so far... and three Glocks for heavier stuff.

Wynn:D

I'll say. I don't think I've got organized part #1. What I do have is leftover project parts from 1911's and browning HPs. Maybe an odd AR buffer laying about....

[CJB]

whats veritable" mean. Just sayin.

Is what grows in the ground and gets eaten, or made into soups. Like veritable ministrone.

Or, coud be its about some poor soul whats lost their marbles big time. Like, "after his head hit the pavement, we know'd he was gonna be a veritable for the rest of his days"

[Killab]

If I was inclined to make up a spares list -

Then from Kahr a slide stop spring, screw and washer.



For clarification, do you mean the slide stop spring (029CM9)
or the slide stop spring screw and washer (030CM9)
or both ??
Thanks for your help.

[Buzzard45]

spring, definitely. (can bend, break,wear out) screw & washer, cause their so darn small they get lost easily.

[muggsy]

If my Kahr breaks down I'll ride in my 1911.
