New Kahr CM9 Range Report

[ArmedMikeQ]

History. Kahr is sending me a new mag. The base plate was loose and would slide right off so I think there is an issue with this mag. Jay at Kahr is sending me a new mag. It should be here today or tomorrow.

Shot 200 rounds today. Winchester White Box FMJ and Federal FMJ. \
12 rounds of Hornady Cridical Defense

Not one issue and is dead on as for accurate !!!

I did have an issue with the slide locking back. Out of 33 mags fired only 4 locked back on the last round.

I emailed Jay at Kahr and told him the slide lock back issue. Within 2 minutes he emailed me back and said that he was sending me replacement slide stop lever along with the mag that is already on it's way.

Great Customer Service and I am very happy with this pistol.

[Hognutz]

You can't beat service like that. They do treat you well at Kahr's C.S.

[ArmedMikeQ]

Anyone know why the slide would not stay back after last round?

Could it be the mag or the slide stop lever or both?

Just curious.

while ur waiting for the parts. take the slide off the gun and now reinsert the slide stoplever and now insert an empty magaazne. See if it pushs up the slide stop lever. Now with a loaded magaqzine do the same thng and now watch to see if any of thoae rounds are hitting the slide stop lever on the inside. they should not.

I am more inclined to think it could be an out of whack slide stop spring. that little bugger ont he left sife by the lever. there is a nice photo tutoriao over on the kahr tech section , I tink under cw34 fixesthat shows how that spring shold look etc and what it purpose is to. I also wold think it could possable a a rrecoil spring issue and jpossable the timing is off on the gun becuase of the recoil spring being somewhat out of whaack. My suggestions are something todo while waiting, bevery sure your recoil spring is on correctly with the outter spring opened end towards the front of the slide

Jocko -

I took off the slide, put the slide stop lever back in and it locks in place. I inserted an empty mag and it pushes up the slide stop lever with the mag follower metal thing. I think this is normal right to make the slide stay open. Right?

I loaded up 6 rounds in the mag. It didnt hit anything.

[jocko]

what u did clears the slide lock lever issue. I think a new one is fruitless. Also another thing that coldvery well becausing itj,,,,, is shooter error. Ur thumb might be hitting that slide lock lever enough to prevent locking open. Try shooting it left handed to see if that issue still stays, and even let another shooter try the gun also. If e can duplicate what your having, then u have eliminated shooter error. I am only suggesting things to check out here. I tend to maybe think if none of those are causing it,k then the recoil assembly might need to be changed, for it eve3n though is new could not be right and letting the gun do its thing. It is all about timing with a gun to and recoil springs pay a very important part of proper timing to....

IMO ur on the path to getting to the bottom of this issue to. watch your thumb this next outting for sure..

Jocko -

Thanks for the good info.

I did make sure that my thumb was not hitting the slide lock lever. I purposely kept my right and left thumbs down and away from the slide lock lever.

I have a few questions for you.

1. On the slide lock spring. Is it suppose to move the round part of the spring(left side) when I push up or down slightly on the spring's right side? Just want to make surethe T5 screw is not loose.

2. Also just to make sure. The slide stop spring is suppose to be over the slide lock lever and resting in a little groove. Right?

3. My symptom about slide not locking back after last round I don't know if this could be an issue with screw not as tight as it should be so the 1/2 moon of the slide lock spring doesn't move when you move up and down the right side of the spring (the part that fit in the groove of the slide lock lever. Do you know?

The slide would lock back but only 4 out of the 33 mags shot.

[jocko]

#1, snug is good, that is all u can do for that sring. Yes it should move slightly,

#$2 yes ur OK there to

Try some defense "hotter" ammo and see if the slide lock still doesnt do well.

Just put a couple rounds per magazine to test out,. It will show up real fast if that isnot the case to.

I still feel you should call and ask Jay at kahr if they would send u a new reecoil assembly. I think if explain to him all that u hav edone to eliminate ay othe rpossables etc and suggest to him " could it be the recoil assembly" he might go along with u .

There is on the kahr tech section a nice photo tutorial, I think by Wyn on the little sprhingny thing and how it should look etc and how to adjsut it if necessary. There are just a few things that can prevent slide lockingopen and u have eliminated most of them, so IMO it is getting down to the slide lock springhy on the left side is out of whack or spec, or the recoil spring assembly is not right either.

I will PM u.

If you insert an empty mag and pull the slide back does it lock with full engagement?

yes

[jfred]

Wouldn't it be nice to hear that no one knows how to rate their customer service because they've never had to use it....in other words things worked right with th product you paid $400 to $800 dollars for depending on the model. Novel Idea huh?

[jocko]

wtell that to kimber onwers. very high percentage of their $1000+ guns go back. Percentages to some might seem high for kahr but they are not,, we tend to assume what we don't know to be true. It happens, nevber good when it happens to u the owner and u have choices then to make: Peddle it, hammer the piss out of it on the kahr forum, send it back and let what the word WARRANTY stands for..

My GLOCK PERFECTION even ha dto go back once, now can u believe that????

[ArmedMikeQ]

ok. I cleaned the CM9 again real good and lubed it.

Bought another 6 round mag and Kahr shipped me a new one.

Kahr is also sending me a slide release lever.

Went to the range this morning and shot another 50 rounds of Federal FMJ.

The first 6 rounds slide locked open. I was happy.

Mags 2 to 5 - slide did not stay open

Mags 6 to 9 - slide stayed open.

I think it is getting better. I think a new slide release lever would help.

I sent back the old mag which on the first range trip the base plate slid off and every part went everywhere. That original mag was a POS.

I really love this CM9 and want it so much to work 100%.

Just a note I have never had a malfuction with it exept the slide not staying open on the last round. So I do trust this pistol just want it to stay open on last round so another mag can be loaded quickly.

[ArmedMikeQ]

Been waiting since Feb 29th for Kahr to send me a new slide lock lever. I contacted them a couple times via email since then and as an update they said it was sent end of last week and should be here this week. Not today since mail already ran. Hopefully tomorrow. :(

[ArmedMikeQ]

I received the slide stop lever today and went to range.


Put 55 rounds through it over 9 mags.


Flawless!!!!! The slide remained open on all of them.


It took a replacement magazine and slide stop lever to fixed the issue of the slide not staying open on last round.

I have found my EDC gun using a Remora IWB holster !

Now time to clean it up and load up 7 Hornady Critical Defense rounds in it.

[krevo]

Good to hear you got it sorted out.

[jocko]

and also alot of times it is the over all power of NEW RECOIL springs kand not +P ammo . It takes some good round power to cycle the slide properly when new springs are in thegun and also if the gun is going thorugfh its breakin period. there is a good reason why 200 round sis recommended by kahr. #1 it gives thegun some rounds down range to smooth itself out with any high spots and also gi9ve the recoil springs time to take their predesigned set. Normally after that the gun locks open as designed. It is all about timeing in these small guns a tad bit off here and there and u can get ittle piddly issues. I really like buying thge 5% extranthg magazine springs from wolffws for my klahgr mags to, as I feel that extra 5% helps get that follower up fast enough towards the end of the magazine to feed properly and also to push that slide stop leve rup fast enough while the slide is cycling.

NOTING beats rounds down ragne though IMO to get things smoothed. SometimesI do think some panic to quick with their kahrs at first: Just sayin

I won't disagree with krevo but I am also skeptical . If a slide stop is out of spec normally one gets premature slide locking open, not the opposite: just saying : but when at kahgr theyt are gonna start replacing parts until the issue goes away.

underpowered ammo is a culprit. compared to +P 9mm Some aftrer a few hundred round shave posted photos of that recoil spring being a 1/2" shorter than new and questioning its life etc. IMO now that recoil spring has taken its predesigned set kand should be good to go for thosadns of rounds: Just sayin.
