Cm9 questions?

[BabyMaker_45]

Hello all! New kahr owner and new to the forum. Picked up a new kahr last week as i need a summer carry option. Have been carrying either a cz75 or a glock 21 for several years. Im up here in MN/ND where its cold 8 months out of the year and need a coat anyway. But iv had my eye on a smaller pistol for some time.
Anyway, iv only had the chance to run about 50 rounds through her but she's a nifty little shooter. Nice trigger too. Anyway my dealer gave me a decent enough deal on this pistol so i took her home happily.

However i do have a question concerning the operation of the gun. I have 2 magazines, the 6 rounder that came with the gun and and extra 7 round mag I purchased with it. During my firing, the last round in either magazine will not fire. Its not chambering. If i eject the mag the unfired round will just fall to the ground. Twice i was able to bump the slide then the last round would seat correctly and fire.

Again i have not yet completed the 200 round break in. And this issue happens only on the last round fired. But it occurs every time in both magazines.

Yes i did completely clean the weapon before shooting. And yes i have used the slidelock to load the weapon instead of racking the slide.
I have also used winchester white box 115gr, and 147 gr. Flat nose, and same issue with both ammo.

Is this an issue that will work itself out the more i shoot it? Or is it a mag issue, extractor?

Any advice would be appreciated. I have not yet called customer service. I wanted to put some rounds through it before the manufacturer suggests sending it in. Any comments would be appreciated.

I do believe its the perfect size ccw, its accurate with a great trigger, so I don't have any buyers remorse as of yet.

Have you tried pulling the mag apart and checking that the springs are installed correctly, that may or may not be the issue, I have the same 2 mags for my CM9 but have had zero issue through the first 100 rounds I shot through it so far.

Yep, Check what Decado said, clean it up good, and see how your next trip goes. May just be break in issues. My CM9 has always been flawless.

The last round failing to fully chamber on 2 different mags doesn't sound like a common problem. Maybe on the 7 round mag if the spring was weak but the 6 round mag should work with most anything. Not sure about the flatnose round but the WWB may be under powered for breakin but should work ok later for sure. Mine eats anything.

Welcome to the forum by the way.

Let us know how it goes.

Oh, and make sure to run it oiled up well next time thru breakin. You may have last time also but just thought I'd mention it. The CM9 is tight as a tick at first but loosens up nicely over time.

Thankyou both. I will take the mags apart. But im not sure what im looking for. How do i know how they should look? Im running it pretty well lubed. I will try some magtec later. I have hornaday critical defense but someone else told me that kahrs typically dont feed that ammo. Ill pick up some other stuff.
on a side note i was expecting the 147 gr. to be much snappier and i was pleasantly suprised with how accurate and soft it shoots for such a small pistol. I can see why so many people enjoy these guns.
Thankyou all for the welcome. Much appreciated

I would suggest that you use 124 gr. or 147 gr. at least until break in is over. Your recoil spring needs to take a set. I have never had a problem with Critical Defense, and actually the bullet shape tends to work better than your average bear.

[yqtszhj]

Like berettabone said critical defense works in mine too.

On the mags, when you take them apart you will see the follower is angled toward the feed ramp of the barrel. Well the spring is angled too and the spring angle should match the follower angle to provide even pressure on the bottom of the follower. If its reversed you may have the problem you are having because the follower is not pressing up the last round as it should. It will make sense when you take it apart and look at it.

Thankyou both for the replies. I will continue to put some rounds through her. I am convinced my extractor needs adjustment. The spent casings are scratching the inside of the slide by where the striker comes out. Not deep but enough to make a guy say, that doesnt look right. I might end up having to send her in. Ill run 1 more box through it in the morning. I know its considered a lower end gun but iv not seen any of my other polymer striker flred guns get al scratched up inside the slide opossite the ejection port and by the striker. Im not an expert but im leaning twoards a bad extractor. That might explain my feeding issues with the next round not seating in the barrel?

[berettabone]

Are you saying that the breach face is getting scratched up? Pics would help as usual......................did you try a drop test? Take your barrel out and just see if different ammo drops into the barrel easily and flush.

[BabyMaker_45]

I did change the spring around in the magazine. I belive mine were in correct the when i got it. But it was worth a try. Im just over the 100 round mark now and failures are only occurring now in the stock magazine and not in the extra 7 rounder I purchased. I think ill just pick up a few extra mags and continue to feed her. Seems more fun that way. Happy to be here still. Thankyou all for the info

Just a recap, im now at the 160 round mark and my last 3 magazines fired didnt have any hiccups. Maybe i really did just need the break in period. Hoping to do some more shooting on easter sunday so hopefully she continues to run good!

Agree with the 124 or 147gr.... I was running 115gr made the switch and I can tell a difference in the way the gun fires. It just feel smoother. Anyway about the magz, I bought 3 extra and never had this issue with any of them. BUT I did clean them with CLP. I sprayed CLP on a rag, wiped the inside and outside of the magz out before I used them. Not sure if this might have prevented the potential last round FTF issue or not, but I do this with all my new magz.

I won't comment on springs, extractors, and other moving parts. I will say that I have four Kahrs and of the four, two were flawless out of the box and two became that way somewhere between 150-200 rounds, as yours appears to be doing. Run the full 200 rounds (or more) with recommended, quality ammo, and then evaluate. My money's on the bet that you'll have seen the last of your issues.
