Ammo Chambering Problem

[Thumb]

The first time I hand racked. After that I used the slide lock lever which made no difference. Only time it would work is when there were only 5 rounds in the magazine. The 5 round mag does not have this problem for some reason.

I'll let you all know if I find anything or not after I work on the mags which should be sometime later today.

Hello Thumb, sorry you are having this problem...If I were you I would call Ian at Kahr and ask if he will trade the 6 round mag for a 5 round, I know they have done this for others likely because they know the extended mags are problematic and they are afraid of a lawsuit if the gun malfunctions in a self defence situation....The longer mags are just not reliable and even for range use you will spend more time messing wih the gun rather than shooting....NEVER carry the it for protection with the 6 round mag which is a d@mn shame because that extra round might come in handy in a bad spot....Kahr will likely swap mags with you so you will then have two that will work and if they won't just buy a couple of the 5 rounders and be done with it and have peace of mind the gun will not jam up on you when you least want it to...

"I know they have done this for others likely because they know the extended mags are crap and they are afraid of a lawsuit if the gun malfunctioned in a self defence situation"
That seems like a stretch to me, most lawsuits I've heard of are for "accidental discharge".
With the cost of most guns today, I'm sure the mfg'ers have enough liability insurance to cover almost anything.

Yea you're right about the lawsuit deal as it would probably be hard to prove why a pistol jammed but they may swap out the mags as a customer service...I really wish Kahr would address all the mag problems with busted followers and extended mags that have chambering issues...Kahr makes such a high quality well made pistol only to have it's image and reputation ruined by on going magazine problems....Kinda like buying an expensive new Cadillac and getting recaps for tires, ruins the overall product IMO....

OK, I took one mag apart, polished up the edges, cleaned, lubed, and put it back together and loaded up 6 rounds. Put it into the gun and guess what, it chambered! Not once or twice but 5 times with the 6 rounds in it. I'll do the same to the other one and see if I can make it work also.

Good for you!

I talked to Kahr and they said they would replace them, just send them back with a description. Thing is now if I get the other one to work, I don't know if I want to send them back.

Good news, good job
Chances are the replacements wouldn't be much better, and now you know what a little detailing can do
Check out the lips on a glock mag, they are mirror polished via tumbling too, and can be much better heat treated steel because they are inserted in to mold before the composit matterial is injected, just like the rails in the composit framed Kahrs.

Well, I detailed the other mag and no go, matter of fact I can't get any of the rounds to chamber in this one. I think I mentioned this before that it was suspicious that both mags did this on the same day at the same time so I decided to strip down the gun and take a close look at it. Looking under a microscope, I think I see the problem but I have no idea what caused it or if it came that way. It looks like there are gouges in the metal and also the plastic is being destroyed. It almost looks like the spring where the slide lock may be bent. I know I was very careful when I did a field strip to clean everything to make sure that the slide lock slid under that spring but I never looked under the microscope before. Something really doesn't look right especially for only having slightly less than 200 rounds through it. Here is a pic of the slide lock that looks like something is scraping it.

Here is a pic of the frame showing the spring and surrounding areas that are being chewed up plus maybe the spring is bent, I don't know?

I would recommend you see what Kahr says about your pics. Otherwise just debur, clean and re-lube until you no longer get plastic shavings. I've seen other reports that this is normal break-in wear. Here is also a video ( from a forum member) that explains how to adjust the slide stop spring: http://m.youtube.com/#/watch?v=c50P7...%3Dc50P7HCAATo
If the link doesn't work just google "CW45 slide stop spring adjustment". Might help?

As much as I love Kahr pistols, and it pains me to say this. It really does. If your sure it's not user error. Chambering problems with Kahr's it is always a good idea to look at the mags first as the cause of the problems. They are junk and need to be redesigned from the baseplate up. In some older guns, especially older Gen 1 Kel Tec PF9's you needed to look no farther than the feed ramps for feeding problems. Some things are so predictable with certain brands. With Kahr's, unfortunately it's there mags. that cause the majority of there problems in many of there smaller pistols.

I sent a picture to Kahr and they said the spring is bent in a little and will send me a new one.

Tilos, I have a Glock also and have had no problems at all after about a 1000 rounds and yes, it seems to run a lot smoother. The Kahr was working great until now except it did not like PMC ammo from the get go but ate up everything else until now.

Yeah, that spring is bent pretty good. You can see at the red arrow where it has been rubbing the frame. Here's how an unbent spring looks (you can probably bend yours back into correct shape while waiting for the new one):


FWIW, the green arrow points to some gouging that can be cleaned up or left alone, but I'd knock down any corresponding sharp edges on the slide stop. The blue arrow points to some slight gouging most likely caused by not having the slide stop above that area when pushing it into place.

In regards to the slide stop wear, some of that is probably normal wear, but I'd guess some might be because the stop spring was bent and the stop was contacting the slide more than intended (especially if your a lefty and shoot thumbs forward). However, I would check the slide for any burrs or other things that could contribute to that. You could clean up those areas of the slide stop a bit.

A couple of suggestions in regards to the feed issue (especially as it was working before):
The spring may be the culprit. I've played with that spring's tension and position found it can be manipulated to the point it caused feed issues (hand cycled).
Make sure to properly lube the slide stop pin and barrel lug.
Check that the extractor is operating correctly (too much pressure or too little movement can cause feed issues).

BTW, those are very good photos

Thanks for those tips, I'll see what I can do while I wait for the part. Also thanks for the good words on my pics. I also build 1/25 scale model cars and have learned how to use the macro for getting close up shots of the detailing I do on them.
