New cm9, range report & problem

[jonholl]

Took out my new cm9 today, no ftf or fte with 50 rounds of Perfecta & PMC 115 gr ball. Suprised by the accuracy of this little pistol.
After ~ 35 rounds the slide would not lock back after the last round, with both rounds. This is a brand new pistol & magazine. Pistol was field stripped, cleaned & lubed before firing.
Any thoughts or suggestions?
Haven't field stripped for cleaning yet, thought I'd get some feedback 1st.
Thanks.
** Also noticed that the magazine wouldn't drop free, where it was dropping free before the problem. I would pull out the magazine, reinsert it empty & the slide would lock back then. After firing again, same problem.

Do you shoot right handed?
If you do: as it's locking back when you manipulate it by hand, perhaps you are riding the slide stop, especially after a little fatigue sets in. I've done it myself (especially with SIGs). I think I'd clean it, lube it well, and hit the range again. If you have similar results, try switching hands to see if that helps with the slide locking back.

You might also check that the mag spring is installed correctly and that the follower moves full length in the tube without binding. Clean the tube while the mag is apart, but forego any lube.

Greg

Thanks Greg, I'll give it a try & also check the magzine.

And check follower for cracks/damage.

50 ronds, IMO u need more rounds thru it to get the recoil spring to take its designed set.. Also, try shooting a magazine of defense ammo which is usually alot hotter than thge ammo ur shooting now. I would be it will then lock open with ease. Just load 3 rounds in the magazine to test and retest for locking. Kahrs are tight when new, recol spring is stronger than heh also. The 200 round breakin in usually gets everythig running right to. My PMJ9 never dropped the magazine freely, and personaly I like that to. I think we make to much to do about that part, just my 21 cents on that. Give the gun some more break in time and I think it will be OK..

Anyone ever use the Pearce "pinky finger" extension, & if so, how are they & any problems?
Bought a new magazine & when checking it out realized with a 2 hand hold my "pistol hand" little finger was under the magazine base plate & pressing against it. I tend to hold a pistol very hard from years of colt 1911 .45 recoil control. Just wondering if that might be what was causing the slide not locking after last round & magazine being a "little stuck"?
Thanks.
** Jocko I also bought 100 rounds of Fed 115 gr. for the range tomorrow .

Yes I have used one. No problems but I just took it because it doesnt work well in the pocket.

[jonholl]

Range trip yesterday, 75 rounds fired. At about round 35 the slide failed to stay back on last round. Looked, & I had my pinky finger under the magazine & pressed hard against it with weak hand pressure. Fired 3 more magazines with same mag & ammo while keeping my pinky off the magazine, no problems. Had no problems with 2nd magazine.
Conclusion (not 100% ), operator error. 1st time owning, shooting a "2 finger grip" 9mm pistol, I'll try the Pearce extension or develop a 2 finger grip that doesn't create problems.
Thanks for the feedback & help folks, appreciated.

Excellent report, thanks for the follow up!

Final update (I hope) on slide problem, it appears to be the original magazine that came with the pistol. Put on the Pearce extension & the same thing happened, even without much pressure exerted. No problems with the new magazine I bought. The original magazine appears to be "narrower", the follower will not drop into place, needs an assist from the spring when reassembling the mag. Anyway, I called Kahr tech support, explained what was going on, & was told to return the mag for a new one. Fellow was easy to talk to.
Good news is I've put ~ 240 rounds through the pistol, 5 different brands, FMJ & HP with no failures to feed, fire or eject.

Good to hear! Did you send Kahr and email about the follower?

[jonholl]

Emailed when the problem 1st appeared, they sent me a new follower but it did nothing. Called today, explained the problem & history & they told me to send the magazine back for a new one. Good service.
I might have picked up on the problem magazine earlier but this is my 1st Kahr & I only had 1 magazine to start with. Hopefully this is it. Main thing for me with a new pistol is it reliable & there were no hiccups firing the pistol except the slide problem.

Glad to see that Kahr took care of the problem and have made you a happy owner!

[jonholl]

Still getting a failure to lock back after last round, maybe 1 out of 5 times. Called Kahr & was told it was the way I was holding the pistol? I know I'm not touching the slide or slide stop. Have > 300 rounds through the pistol, so shouldn't be a break in problem. New to Kahrs, is this possible?
Thanks.

If you are right handed, shoot several mags left handed and see what happens. When the gun is fired, our fingers sometimes go places we don't think they do! Try pulling the slide back with the empty mag in it. Does it lock back every time? If it always locks back when you do it manually and when you shoot left handed, then Kahr likely correct.
