Guys I posted a video on youtube of my CW9 barrel and how loose the cartridges fit in the chamber. Other than the loose chamber it is a fantastic pistol.

Let me know what you think.

hmm that is very intresting. what kind of groupings where you getting with it? I do not have the setup to test mine but would be intrested to know. Please update when you talk to kahr. I wonder if they are on the loose side for reliability.

I just checked mine by pushing the round side to side like you did, with a Speer GDHP 124 +P and it did not move the way yours did. I didn't check my chamber with a caliper though, but the round clearly didn't move as much. Keep me posted on this I'm very interested in hearing what/how it went wrong.

Jshull...I have not tried shooting the gun from a rest, so i'm not sure how accurate it shoots. It does point naturally for me. I shot it at about 10 yds standing and almost all the rounds went into a 6 inch circle with slow fire. I also did about 50 rounds of rapid fire mag dumps to see how it would run. The loose chamber did not see to hurt it in any way that I could tell. But I think if the chamber is to loose your brass may split,

Klutch....that is what I was thinking. Mine must be one that slipped though the cracks. Kahr has a reputation for making good quality firearms.

I called Kahr today and they said send it back and a gunsmith will look at it. They are emailing me a return label.

Very interesting indeed....Does this have anything to do with how dirty the gun gets after shooting it? I have an XD and a Ruger and the Kahr by far is the dirtiest.

Also I noticed that you chamber was loose side to side but tighter up and down, at least when you measured it. It appears to be oblong (oval) for some reason. Maybe you're right it just slipped through the cracks; it does happen.

I checked my PM9 out today and it is very tight, no sideplay like ur dial indicator shows. I would say it is a bad barrel, ..

I just checked mine and there is some play hard to tell if it's as much as yours. Like I posted earlier, wondering if thats the reason why my gun gets as dirty as it does after only 50 rounds?

I just measured my barrel after talking with JEC PA and it is at .3850 all the way around I think bad barrel also with yours. There is out of SAMI spec and also out of round, Kahr will make it right for you.

Thanks guys....I was pretty sure Kahr would not make their chambers bigger than SAMII specs.

Do they make the CW barrels?

I think the P series are polygonal and are walther match grade.

Jec_pa may want to get some digital calipers for less that $50, they come in handy for all sorts of thing and if you want to start reloading you will need them.

He lives close enough to me, he can just use mine.

actually kahr doesnt make any of their barrels. . They come to them in 3ft blanks already rifled and then kahr does the rest of the maching to a finish product, the chambering area is all done by kahr, so the screw up would be at kahr..

Did you check it with various other brands of ammo? Different runs of the same ammo? Is the chamber clean and is the round headspaced correctly? Please send it to Kahr (or a reputable gunsmith) if you have any reservations about it. Posting something like this on Youtube and on a forum like this is guaranteed to get a sh*tstorm started. Have it checked by someone who knows what they're talking about and THEN post the results.

touch it, send it back to kahr, they made it, they know exactly what it should or should not be. The will replace the barrel with no problems if needed. Jsut because onehangs a shingle on his door doesn't mean they are qualified..

I don't know about a dookystorm but posting it he is only seeking advice as to if anyone else has had this problem; most likely to see how they rectified it. Even with different ammo types they are still 9mm and round just like other ammo would be but in the video the chamber seems to be oval and when he measured it found this to be true.

Sorry, but I thought emphasizing a "qualified" gunsmith was direct enough. I don't see anyone suggesting he look for the first guy with a shingle hung out, although that would probably be as productive as posting a Youtube video and coming on here.

Klutch,
He could possibly have some out of spec ammo, which is probably as much, or more, likely to be the problem. Watching a Youtube video is no way to determine if a potentially dangerous problem exists with the gun. And in regard to him measuring the chamber and finding it out of round. What did he use to measure it? How did he measure it? He had to come on here and ask if anyone thought it might be a problem, I really don't think he is qualified to determine if it is or not.

To the original poster, please don't take this personally, but please don't screw around on the internet. Have a QUALIFIED gunsmith look it over or send it back to Kahr.

dont take this personally but if you read, #1 it is already on the way to kahr. #2 if you watch the whole video he doesn't just measure the with ammo but with a set of calipers. it is no doubt out of spec. further more its his weapon, he can do whatever he pleases. I know I came to this forum for advice/research before I bought my cw9. I am sure alot of people do the same. if we can post good reviews time and time again I more than think we should know when there is a problem. I mean fit and finish of the gun itself are wonderful, mine shoots like a dream, but if customer service/warranty sucks why deal with the company. bottom line he was looking for advice. In my opinion he looks more qualified than most gun smiths i have dealt with.

No one said we were more qualified than a gunsmith. Also no one said don't take it to one or don't send it back to Kahr. He measured the chamber with a set of calipers(out of round) he also measured the amount of side to side play with a dial indicator. I'm not saying he's qualified for any repair but he is definitely qualified to realize there is an issue and found the issue using the proper tools(kind of like going to a mechanic). He also did not ask us "if" there was a problem he ask if any of us who own the same pistol have chambers that allow a very popular SD round to move in the amount that his does. If you really believe we would tell someone to fix it on his own simply by viewing a youtube video you are very mistaken. This is an internet gun forum, we talk about guns, and that's what we have done here. You expressed your opinion of taking it to a gunsmith, some of us have expressed ours by saying contact Kahr, I'm pretty sure Kahr will know what to do better than any "qualified smith". I'm a professional auto tech for 13+years, and when we can't figure the problem out we call the manufacturer cause the made it and know more about it than we do.
I'm done with this unless it pertains to the OP.
