Am considering buying a CM9, and I have a question about clearing any possible jams.

From what I've read, the proper way to load the first round into the chamber in a CM9 (maybe others, too, but I haven't checked) is to lock the slide back, insert a freshly loaded mag and depress the slide stop. Sling shotting the slide is not recommended, right?

Here's my question. While I enjoy using the slide stop on my other pistols as is suggested for the Kahr, what if there's a jam, or failure to eject, and the gun must be cleared. Will normal tap and rack drills work properly with this gun?

Very important question for me.

Thanks!

Yes, tap/rack/pull will work just fine.

The main issue is that Kahrs are really tight, and some people tend to ride the slide forward, which can cause a Kahr to not go fully into battery.

A proper slingshot, especially as your gun is more and more broken in, will work fine.

Thanks, Glock23. Will it become similar to the way my Glock 17 and G26 and G30s operate?

How long before the gun breaks in? If I get one, the first time at the range will probably be 250-300 rounds. Should that do it?

It may, it may not................but usually it's enough. In my case, it was enough. Firearm is still very tight, even after lots of rounds.

I've heard different things from different Kahr owners....but my PM40 will load either way....slide stop at first and when broken in it worked just fine by slingshot...properly done. I always load for SD from slide stop, but won't hesitate to switch to slingshot on the range.

As others have said, it is a tight gun and takes some time to break it in properly. I did the prep described on the forum. I worked the slide over and over again to help debur and loosen things up....followed by another cleaning and lube....before going to the range, shooting. After shooting I always clean. I repeated the break in shooting several more times without any flaws. I've used various types of ammo with no problems. I am very happy with how mine has performed after a good break in period. Understand however, it remains a very tight tolerance gun. Properly broken in, cleaned and lubed, I'd be surprised if you have any problems with yours. They are a great gun but the long trigger takes some time to adjust to. Folks on this forum are also very helpful. JMO.

Thanks, Gary.

With all the talk I've heard about the action being really tight, there's another concern I have. When I first heard about the Kahr PM9 and then the CM9, I really liked the small overall size of a gun chambered in 9mm. On the outside, it somewhat resembles a Glock, of which I have three. All those guns run flawlessly (G17, G26, G30s) and I've only had one failure to eject a round in probably 5,000 rounds fired cumulatively. One of the selling points for me with the Glock is their ability to run really dirty.

If the Kahr is as tight as it sounds, it seems to me that if I'm not really careful how clean I keep it that it's performance as a self-defense gun can be compromised. What think ye? How many rounds through the gun without cleaning before I start having problems with functioning?

I personally don't consider it an issue Your not gonna shoot 5 or 600 rounds at a range session and then stuff it in your carry rig and go about your day.

Your gonna clean it and it's be fresh and ready for the longest fire fight you might ever encounter.

I've put over 400 through my PM45 at one session and it wasn't slowing down any at all.

These little guns aren't really designed for long range sessions anyhow. Usually after a 100 or so your just slinging lead anyhow. Out of any gun, not just a small one.

Don't hesitate to buy the cm9! I carry mine every day and shoot the crap out of it at the range (used to be twice a month now more like once every other) and have not had a single issue. Yes I had to use the slide stop to chamber the first round before the first break in at the range but after about 300 rounds I now easily chamber a round with the proper rack of the slide. I love the reliability, simplicity of use and the fact that it disappears in a simple kydek (pj holster) iwb holster. I can easily say my cm9 will not pass to another owner until my death!
Now go buy a cm9 and let us know how it goes! :)

What you say makes a lot of sense. I just wouldn't like to find out that after 75 rounds of dirty ammo at a range that the gun would start failing to go into battery, and so on.

A typical range session for me is probably 100 rounds from each of two or three guns.

Mastering a CM9's trigger hopefully won't be too big a challenge.

Thanks for your comment.

Slingshot my cm9 and its fine all day long. But you better not stop at anytime. Pause for a second and its stopped. The casing will get stuck on the ramp. Now here is the strange thing. Minus 1 out of any mag and this problem goes away. Even my wife can slingshot it this way. With a full mag she is about 50/50. I've tried polishing the feed ramp but that's clearly not the problem.

I work it like my glock s, but you can't baby it.
Mines getting better every time I take it out, and I'm just getting close to the break in. I need to go put another 50-60 and then report back.

well then don't stop, do it right asu said and it is OK. Better yet use the slide stop release if it bothers your wife to do right. I think kahrs are hardto hand rack, just the nature of the beast. Not sure if u pause on utter guns u might not get the same results. Some guns are just a pu$$y to rack. My G19 just amazes me, doesn't matterhowI rack it, it feeds right, but I don't compare it in exxence to my kahr. I know my kahr is harder to hand rack so I either do it right or it lets me know.

I personally don't consider it a problem,just two diferent guns. anutter reason why kahr recommends in their manual to use the slide release lever.

with a closed slide and a full magazine,that op round is up very tightly againstthebottom of the slide, Thatis one reason why it is harder to hand rack. takea round out of the magazine and DUH there is less upwardpressure and there fore it shouldfeel easier to hand rack.Just sayin.

Some here have reported in the past the difficulty of loading the magazine to full capacity due to the strong sprig pressure, so consider if you get it fully loaded and ur shoving a magazine in the gun that that top round is gonna be pushed down a tad by the bottom of the slide bar.

I never load my G19 magazinet o fullcapacity by hand, just a total b!tch to do, so ifI do it at all the UPLULAWORKS FINE BUT FOR RANGE USE, i runmy Glocks are 10 rounds and for my PMJ9 I run my mags as 6 rounds for range use--why fight it???

I've had seven Kahrs and have used the sling-shot method from the first mag on every one of them. There is no problem if you execute it properly.

Glad to hear the good news about racking! Sometimes it's the only way to get a round in the pipe. Imagine having to drop the magazine, then open the slide until it stops and lock it there, reload the mag, and then drop the slide release. That would kill a deal for me, and it could also get you killed if that were to happen at a critical moment.

Based on my research on Kahrtalk and elsewhere, and on all your good suggestions, this afternoon I purchased a CM9. Because of where I live, it will be available to me only in three days. Some states... well, you all know that.

I haven't heard you say anything that should cause you an issue BB. I ran a test with my K40 going over 700 rounds in multiple sessions without a cleaning. Ran perfect. I finally cleaned it just because it was bugging me...not because of any issues. My MK9 is over 10 years old and still really tight. I consider that an advantage and a testament to the gun's quality. But I can slingshot it no problem. Welcome.

A gunsmith I know told me that 1911s in particular need all sorts of fitting and tweaking and polishing and lapping to become totally reliable.

Anybody try using a bit of lapping compound to smooth the break-in process?

Anybody have particular experience with this and how it turned out?

What I'm thinking of is this stuff, available on Amazon and in auto parts stores:
Permatex 80037 Valve Grinding Compound

Not necessary and it would probably only make a big mess.

What's the saying I'm looking for, I hear it frequently from an old goat with an effection for sheep.

Shoot it like ya stole it.

You certainly shouldn't need any tweaking or polishing to get it running right. As for the lapping compound: might speed up the process but most here would just recommend some time and some plain old shooting. Give the gun's surfaces a chance to mate to one another. If you encounter problems, let us know. Many get solved right here on the forum. Some need to go back. Most work just fine as they are.

Yup! With in reason of course and who knows the true definition of reason, ya know?

You and it will benefit from quality time together, it will get smoother and smoother and you'll get more accustomed to the trigger etc. A win/win and beats messing around with potions and remedies.

whatis lapping compound, is it the samething engine people us to seat valves/seats? Just asking,

I would certainly hateto thinkI hadto lap a gun, for IMO it is different than just polishing like recommendedon the kahr forum. nOT that maybe 1911's don't need somekind of crapola to make them work right, for after allthey are 45's. Just sayin

Yes, it's a compound used for seating valves and so on. Not so fine as a polish.

Well, from my experience with Glocks and a Ruger SR22P, judicious polishing and even grinding (shudder... had to do it to one of my pistols as the engineers left something square that should have been rounded off, resulting in failures to load cartridges because the slide didn't complete its rearward motion) can result in a tremendously superior shooting time at the range. Perhaps the Kahr will be perfect from the get-go! I sure hope so. Time will tell.

I just bought a CM9 and went thru the break in prep here on the forum. I probably did 350-400 racks of the slide and then a thorough cleaning and lubing. Went out Sunday and ran 100 hundred flawless rounds. Not a hitch at all. I don't think you will have a problem if you follow the advice from the forum folks. Now mine is still tight but I noticed that it has gotten easier to rack the slide.
