View Full Version : CM9 Issues

Bought a new CM9 Saturday. That night I took it down for cleaning. Had a great deal of difficulty removing the slide. It seemed as though it was hanging up on something. Finally came loose with manipulating the trigger & slide. Cleaned & oiled. Had hangups trying to replace slide. Once on it functioned properly. Ranked slide, dry fire, etc. Took to range Sunday & had FTF about every 10 rounds (Remington FMJ). Found this to be unusual since my CW45 has performed flawlessly. Shot 100 rounds hoping FTF issue would sort itself out. Tried Winchester JHP. 3-4 mags, no problems. Then had FTF issues again. I was still thinking that I still need more break in time. Then, after each shot the slide would not fully return to battery. Slide would cycle but come 1/8" to 1/16" short of fully seated resulting in click instead of bang. Hopefully a more thorough cleaning & lubrication will help. I bought the CM9 for carry based upon my great experience with my CW45. I am sold on Kahrs but the issues with my CM9 are disturbing. After 200 rounds, if this keeps up, I will contact Kahr customer service and, based on what I have seen in these forums, I am certain I will be a happy Kahr 2 gun owner.

I also had problems removing the slide on mine but after watching a U Tube video showed pulling the trigger and , I think, holding it while removing the slide helps.

Hi. Welcome to the forum. Since you already have a polymer Kahr, I won't jump to the conclusion that you did something improper in disassembly/re-assembly... spring orientation, etc. :)

I would check the extractor and see if there's enough clearance for the cartridge rim to fit under the "claw". Try sliding a cartridge into position between the "claw" and the breech face.

Another possibility is the torx screw holding the slide lock spring in place. Check the spring for damage or looseness, but DON"T OVERTIGHTEN the screw... steel into plastic threads... could strip those easily.

Watch the Kahr video for disassembly and re-assemble for proper procedures. Maybe it's something you overlooked.

Good luck and let us know how things go.

Update: Called Kahr, as I expected, customer service matched their firearms - great. New slide spring assembly is on its way. Once that is in place, will try the other suggestions. Thanks.

I suspect the ball ammo just didn't have enough get go. It worked fine with the Winchester hollow point.

I think it just needs more rounds to smooth things out, then the ball ammo should work fine.

the colonel is dead rioght. Normally range (ball) ammo ) for a new kahr with stiff ass springs sometimes will produce those issues. Shoolting defense (hot) ammo and it works OK certainly is an indication of that. My bet after a few hundred more rounds when the gun takes its designed set, everything just smooths out better and it will funcition with any ammo.

U might check ur cm9 recoil outter spring and count the coils. It should have 13 and not 15. tey made a change down to 13 due to some complaints about hard hand racking an failure to lock openb on the last round. check that out...

Yea try a different brand of ammo. WWB runs fine for many but also has the most problems of any. Also the 115gr bullets for many my not give you a full slide cycle. Try to find some 124gr loads. Not so easy today. I found with my cm9 it was simplier to find good 124gr+P hp that I wanted to use for CC and started with a box of that. Then it would shot 115gr fmj .

I seem to remember doing some extra slide racking by hand while it was empty during the break in period. May make sense doing that especially when ammo is especially harder to find.

If you do this type of hand racking exercise, would recommend the use of gloves as the serrations will likely do a number on your fingers in short order.

Save that old spring as a spare. There is nothing wrong with it that breaking in your gun won't fix.

When you go to remove the slide, pull the trigger about half way back while sliding it forward. That's the sweet spot on my CM9 anyway.

The CM9 will smooth out. It's a real nice gun.

Got new slide spring on 9/24. Placed self imposed 0 count on break in period. 50 rounds Remington HTP on 9/25, 100 rounds on 9/26, 50 again on 9/29. All told 3 FTF in first 150 and none in last 50. No failure to return to battery. As I expected, I am just as happy with my CM9 as I am with my CW45. Small issue, non issue really, last round with 1 mag have FTF on last round. I now carry CM9 6 + 1 with spare mag of 5.

My problem from the start was putting the slide back on the frame. Sometimes it would go on easy and others it would catch on something metallic and only after reseating the spring several times it would all the sudden slide on easily. I finally figured out that the open end of the spring had to be facing downward. If it was facing upward it would catch. I don't know why but it seems to have fixed the problem.

It's been discussed in other threads that the open end of the spring needs to be at 12 o'clock. In other words, toward the barrel. Not sure if your "down" means as you're holding the slide upside down but whichever way works for you that's a good catch.

upwould be condisered thetop of the slide, down would be considered the bottom of the slide, no matter what or how u hold it... Basicaly the open endis supposed to go towards the top of the slide, if one findsit works OK the opposite way, then good for that person's paricular gun... anutter thing one can do with that openend of that spring is to open it up even a tad more and then u won't have that spring wanting to creep out the samehole as the recoil rod when reinstalling it..

I guess I missed that thread so thanks for the info. I will have to try it some different ways but at this point having it at the six o'clock position makes it work.

Well, I found out that if the open end is definitely at 12:00 then it works fine. I think I wasn't really pointing it toward the slide but just shoving it in there which is probably why sometimes the spring would extend out of the front. I am much happier now that I can put it back together without any cliches.

I picked up my new CM9 today and have spent the last hour trying to get the slide stop pin out.I line up the witness marks and the pin won't budge.It's like it is welded in.I tried prying it out with a screwdriver.I watched a youtube and the guy on there just pulls it out with his fingers.Any suggestions?Thanks!

Finally got it by tapping the pin from the other side.

Don't worry, after a range trip or 2 you'll be able to pop it out with your finger. They're all tight in thd beginning.

Line the marks up, and tap out with the cushioned base of a magazine. Works every time. Always on hand, and will not mare the finish.

thats anutter reason why the pin sticks out on the right side to. U can tap it with a brass hammer and it will pop right ouot. Its not supposed to fall out. I always put a dab of grease on that little springhy to before reinstalling the jpin, and also on the pin itself..

I was so intent on getting the marks to match up that I never looked at the other side.This is the tightest pistol I have ever seen.Getting the spring and rod back in was also a chore.I went to the range today but there was a 2 hour wait.I plan on putting 200 rounds through it tomorrow.Many thanks for all the responses.

200 IN ONE SETTING is a bunch, so be aware of grip changes etc that can cause malfunctions. What happens a sooter with his new peace is so escited about shooting it that after X number of rounds the shooter gets tired and doesn't realize it and ten things happen and the gun gets blamed. If I could give a recommendation. limit ur first shoot to a 100 rounds with sme breaks in between. If u get a 100 flawless rounds thruh the gun, then IMO it is good to go. that 200 round recomme3ndation is what kahr would like to see done but it doesn't have to be done in one setting. Shoot good ammo, not junk stuff, Ur gun is new the recoils springs have not taken their designed set either, so sometimes with fmj what I call range fodder ammo, can produce failure to lock open sometimes. Once the springs take their set ur good to go. If u do encountert some failure to lock open, then try a box of defense ammo that is usually hotter and normally + rated. My bet is that it wil lock open perfectly. Shoot close to, keep ur range at 7 yards, This ain't a target gun ad the looooong but smooth trigger takes some time to get the ang of....Hopefully u did the propper prepping of ur kahr and read that thread to c heck out things that should be pre-checked..

I put over 100 rounds of 3 different ammo types through it today and it was flawless.The trigger pull will take some getting used to.Thanks for all the insight!
