I just bought a Kahr CW 40 .40cal. I took it to the range right away to test out my new conceal carry. Everytime I loaded up with one in the chamber, the first shot would cause the magazine to fall out. This would only happen if there were 6 (mag capacity) +1 in the pistol. If i had three or four in the magazine, it would not happen. I didn't get to the recommended 200 rounds to break in the gun because I was afraid something might be wrong with the pistol and didn't want to do more damage to it if there was. Has me pretty steamed. Anybody have any ideas on why this is happening? And yes, i am SURE i had the mag secured in tightly. Kinda puzzling, other than that though, the gun shoots very well.

I also have a cw40, but I didn't run into this issue during the break in period. I would only load it with 5 in the mag, and one in in the pipe. If it is still an issue after the 200 round break in period, I would buy another magazine and see if this clears it up.
If not, I would ship it back to Mass.

Kahr has had problems in the past with the bonding of the metal bearing surface to the mag catch. If you lock the slide back and look down at the mag catch you should see a metal piece on top of the black plastic catch. If its not there that's your problem. Kahr will send you a replacement mag catch to fix the problem or you can send the gun back. I had this issue with my PM40 initially. Emailed Kahr on Saturday, had the mag catch in Wednesday's mail, gun has been great since.
This not a break in issue, unless there is a burr preventing the mag from fully locking in. You can check this by noting how the mag catch sits in the frame with no mag vs mag inserted when you look at the side of the catch opposite the one you press to release. If it sticks up a bit you can try pushing the opposite side to fully seat it and then look to see why its not fully engaging. Do this with the slide closed and the mag loaded fully (chamber empty!).
If the metal bearing surface is not there or is at an angle instead of perpendicular to the magazine the problem will get worse the more you shoot.
Its possible, but much less likely, there is an issue with the mag catch cutout being wrong, so trying a different mag is a good idea if you can and none of the above seems to be the issue.

Thank you Wally and Dan-O for your replies. When i look down in there, i do see a msmall metal piece on top of my catch. It's small, and is actually the one that inserts into the mag to catch it. I assume this is the one i am looking for. It is bent a little slightly. Not sure if that is a problem or if thats how it should look. By looking on the opposite side, i am sure it has seated correctly while at the range. I wiggled the mag and everything to be sure that it was catching correctly. The side opposite the mag release would stick out further at first while sliding it in (of course), then drop back in showing that it had clipped into place. Not dropping back further into the gun though as if there were no mag in it at all. I'm not too gun saavy. I have a duty carry glock and a recreation taurus and all I ever do with those is field strip them for cleaning.

If the metal on the catch is angled or bent, its probably the reason the mags won't stay in when full.
Call Kahr on Monday, they'll likely send you a replacement mag catch if you feel you can swap it out. If not you'll have to return the gun to them, its cheaper to have your dealer send it back for you as FFL to FFL can use cheap shipping. Maybe Kahr will send you the replacement catch and your dealer could put it in if you are not up to it -- its not difficult to do.

I had the same problem today with my new Kahr PM9. Today was the first time I've had it to the range also. Twice the magazine popped out after I fired my first round from the 6-round magazine. At first I thought that I had one of the plastic magazine catches, but after I got home and disassembled the pistol, I found that I actually have the newer, metal magazine catch.
So I was a little puzzled, until I reassembled the pistol and dry-fired it a couple times, and I realized that I was resting my right thumb on the magazine release button. I think I was concentrating so much on not "limp-wristing" when firing that I was actually squeezing the magazine release button slightly, thus allowing the magazine to drop out.
I'm going back to the range next weekend, and I'm going to change my grip slightly, so that I'm not touching the magazine release button at all. If the magazine still falls, I'll give Kahr a call. I'm pretty sure it was my fault though.
Incidentally, the magazine drops were my PM9's only failures, in 84 rounds of 147-grain 9mm hollowpoints (50 Winchester Silvertips and 34 Speer Gold Dots). No problems with the recoil either, with these rounds. Very controllable. And even when I intentionally limp-wristed it, I had no FTF's or FTE's.

never thought about updating until now... I brought the pistol back to the dealer, who sent if off to kahr. While it was gone, I actually read the manual, and it said to depress the mag release while inserting the magazine. When i got the pistol back, i noticed that when i slid the magazine in, it physically stopped at the mag catch, i have to depress the mag release button, and then finish inserting. I imagine i don't HAVE to depress it, but then i might sheer it off, which is what I could have done in the first place to cause the problem. So... a couple things come to mind, I'm not gun saavy but shouldn't the mag catch be like a door catch and slide in easy one way but not back the other? Also, if I have to put in a new magazine FAST, I dont want to have to worry about putting it in correctly, or ill break the mag catch, and now it will drop out again with each shot......just my update and thoughts... oh..but the gun does shoot well now...mag isnt dropping anymore....

call karh, and I am sure they willsend you the new metal magazine catch. It is a no brainer to install yourself. That wills ove your problem.
I have never had one issue with magazines popping out of my PM9 in the7 round or 6 round magazine and I have at least over 2100 magazine insertions so far through my pm9 which has 12,650 rounds through it. And I have the plastic magazine catch to (the older style) all the new kahrs now have the metal catch, so more than likely there have been some issues. The plastic catch is well made IMO with the metal insert in it and probably truth be known, it was more expensive to even produce that way over a cost metal one. Call kahr, , don't send it back, ur issue is solvable in house. That is a great little gun IMO>

It is a common problem with the Kahrs, and unbelievable that they let thousands of them slip through their quality control.
They also have a tendency to choke on hollowpoints, well beyond their break-in period. If anyone knows how that can be solved without sending it back at my expense for a third time, please let me know.

I guess we all judge things by initial experiences, but I've got a 6 year old K40, and a 2 day old CW 40, and neither has ever failed to chamber a 135, 155, 165, or 180 grain JHP of Remington, Federal, Winchester, Speer, or Corbon manufacture.
That fabled Kahr 200 round break-in period was a 1 round one for me on both guns, as it has been all all my quality semi-autos.
I had a magazine follower break on one of my K40 magazines, and Kahr not onl sent two followers, but a complete spare magazine.
Could you please describe your problem(s) in a little more detail?

I have no issue with any hp's out of m,y k9 or Pm9, none, nadda, zero. just goes bang every time. After owning kt's for 3 years, I was just not used to having a gun to go bang all the time like my kahrs have. Course I don't even talk about my G19 going bang all the time. It just does......
