New member here and new to Kahr, not new to defensive handguns.
My first time out this afternoon with my new Kahr MK-9. It was disappointing at best. I read all the stickies, did the initial clean and lube. Checked both of the magazines for correct spring installation position. I even checked the bullets were not touching the slide stop with the slide removed. The slide stop spring is correct, it's spring loaded in the down position. The trigger is awesome, the machining is wonderful, it's all stainless steel... But it doesn't run.
200 rounds of Winchester White Box 115 gr. FMJ for break in.
50 rounds of Remington Golden Saber 124 gr. std velocity next.
25 rounds of Remington Golden Saber 124 gr. +P after that.
Even with an "aggressive" thumbs away from the gun position, the slide stop self engages. So then I fired weak hand only (left) and surprise, same problem.
The slide stop self engaging problem happens with both magazines, and at no particular place in either magazine. It happened at round #2 and at just about any other point in either magazine. Every time I had the malfunction, I pressed the slide stop down and resumed firing. I don't believe I had the malfunction twice in any one magazine. Any suggestions before I call / email Kahr and send it back for repairs? Other than the slide stop self engaging problem, everything was good. If I can get it to run, it will be a great CCW choice.

You checked everything that it could be & all I can think of is the recoil assembly. That was happening on a p238 I had so Sig sent me a new design spring and it never happened again. My mk9 is one of my favorite guns. Almost forgot I would call Kahr.

without my repeating it. look at the kahr tech section, under propper preppingof ur new kahr. there are soe thingsthere to check out and eliminate as possabilities. there is also a nice photo tutorial on the tech section showing the proper alignment of the slide stop spring to. under cw45 fixes. U need to checkthem out before sending it back. it could just be a minor thing.
It does sound to me like it is in the sldie stop spring, either being maybe to loose and maybe a slight snuggining of that spring can stop that. It that spring is a tad loose u will get what ur having. I doubt if rounds are hitting the insdie of the slide stop but easy tocheck out to. the prep guide explains all of that.
Other than the thumb thing which u have eliminated to, there is only 2 things left that can cause what is happening.
#1, slide stop spring.
#2 rounds hitting inside on thge slide stop lever.

What Jocko Said ... +1
And I am voting slide stop spring. NOT locking back might be recoil related, but locking back when not intended would not be recoil system. As Jocko said ... only 2 mechanical possibilities.
Cee_Kamp ... I know it's frustrating, but stick with it, adjust the spring, and if necessary call Kahr and have them make it right. In the end, you will love this gun more than anything ... or you can sell it to me!

I had the same problem with my MK9. I tried everything to figure out what was causing the slide to lock back but in the end it took a couple of trips back to kahr to fix the problem.

You could try with slide locked no mag pull the slide back & see how fast & positively with a little click how the slide stop comes down. Could it be that the part of the spring that actuates the stop is a little short? I'm sure whatever it is will be fixed.

Any suggestions before I call / email Kahr and send it back for repairs? Other than the slide stop self engaging problem, everything was good. If I can get it to run, it will be a great CCW choice.
I am having the exact same problem on a brand new MK40. The first time I went to the range, I shot 240 rounds, and had three failures, exactly as you described. On the 2nd or 3rd bullet, the slide would lock back, like the magazine was empty, but there was three or four bullets still in. I pressed the slide stop down, and the gun fired the rest of the magazine fired ok. The second time I went to the range I fired 100 rounds on MY MK40 and had two failures. I fired 100 rounds from my Glock 21, with no problems. I am using American Eagle factory ammo, so I doubt it is the Ammo. It was suggest that my thumb was hitting the slide stop so the next time I was at the range a fired another 100 rounds with two failures. I was very careful with my grip and am sure it was not my grip causing the problem.
It has been suggested that it might be the slide stop spring but I have visually inspected it and it looks ok. I called Kahr service and was very disappointed with who I talked to. They offered no help and suggested it was my problem. I need this gun to work 100% of the time, because I bought it for Self Defense, but cannot use it for that if I am not 100% confident in its performance.
I am very happy with the gun, even at the third time at the range, it is reasonably accurate. I was able to get 96% of my shots in the inner two circles. I need to get more exprience with it, becasue I am use to Glocks, as I can usually get 98% if my shots in the inner circle on an NRA D-1 target with my Glock. But I need it to work 100% of the time.
I would appreciate know if you figure out what is causing your problem, or you get a better response from Kahr than I did.

With the polymers, the spring can be bent or wind up UNDER the slide lock lever, instead on on top, and this will cause slide lock back with almost every shot. The free end of the spring to the right can get bent, too, when inserting the slide lock and pin.
Tightening the screw holding the washer, but not too tight, may help, too. My p40's screw needs tightening sometimes. If I start having slide lock-back problems, this is usually the case. Sometimes you just need a new SL spring. I keep spares for all of those parts on hand for each pistol... polymer, anyhow.

That pic of the poly gun is nothing like my mk9. The top part of the spring winds up & over then down past the screw to operate the slide stop. The bottom part of the spring is contained in the cutout for the spring. Whichever way is right is the way it works & mine works.

what this forum really needs now is a very good poto of the MK slide stop spring on the side of the MK frame. This will tell us alot..
Kerby9mm: haveu had that spring on ur Mki out to see what it looks like. On the poly khars, the end peace thatu cannot see is bent and goes into a dedicated hole in the poly frame and the screw and washer merely hold it in place, I was un aware that the MK spring and the poly springs were built different.

I never messed with it because I didn't need to. I only have a phone and don't know how to post pics. The spring goes around the screw is bent at angles then the top of the spring goes down to the screw bent again to protrude into the cutout to go on top of the slide stop to keep it down. If you give me your Email address I can send you a picture.

Thanks for posting up the pictures! I have rechecked my MK-9 today. The slide stop spring appears to do it's two functions. (1) It holds the slide stop in place with the left side of the spring laying in the shallow groove on the slide stop shaft. (2) It applies downward pressure on the slide stop lever with the right end of the spring.
I also checked again for bullets hitting the slide stop, seems to be sufficient clearance. I'm at a loss for solutions. The screw seems tight enough and the spring acts like two separate springs, ie: moving one portion of the spring doesn't move the other end.
I was surprised to read the OP had the same problem and Kahr did nothing. If that's also the case for me, I'll purchase another slide stop and it will see some time in my Bridgeport vertical mill. When I'm done the Kahr MK-9 will not have slide lock back capability any longer. Anybody ever shoot a Seecamp?
cee_Kamp
01-01-2013, 06:39 PM
And now that I think about it, the WWB 115 gr. FMJ ammo has a much sharper angle on the bullet than the Rem. GS hollow points. (more pointed) So it's unlikely the slide lock back malfunction is caused by bullets hitting the slide stop. The malfunction occurred during the initial 200 round break-in with the FMJ as well as with the Rem. GS self defense ammo.

I don't know if this helps, but I've heard the grip screw is the same as a 1911. I haven't verified this myself though, if I was at home right now I would.
jocko
01-02-2013, 06:12 AM
thread size they are, some lengths could be different. Somehere have bought the 1911 stainless grip screws and filed them dowto fit kahr grips, so they don't grab on to the magazines. I think rownlells even sells shorter 1911 screws for thin grips. The COLONEL wqould know that for sure.

Have you ever called Kahr about the problem? I place another call today to see if I can get a different response. I am not sure if I should replace the slide lock, or the slide lock spring. Maybe I can get them to send me a new spring.

Yesterday at the range I tried shooting with my left hand, to prove I was not accidentally hitting the slide stop. I had two failures left handed and my son had one, in 100 rounds.
Talked to a nice lady at Kahr today, she said, since my gun is new, it sounds like a defective slide stop and she would send me one. I will let you know if this works, but it is a lot better than RMA the gun.

Well.... After waiting for better than half an hour for a "live body" on the phone, Kahr's automated phone system dropped my call. I called back and finally spoke with a person, sadly NOT in customer service. I got an E-mail address from them for customer service and sent them an E-mail tonight. But while on the phone, I tried to go to the option for the administrative offices so I could tell them they need to hire MORE customer service folks, that's when the call was dropped the second time...
So, are they understaffed, or buried with problems, or both?

My suggestion is to take a deep breath and remember that you catch more flies with honey. You were put off by a bad experience, but countless others (myself included) have had GREAT success with Kahr CS. Remember the time of year and the political climate. Every gun manufacturer and dealer is overwhelmed right now. Patience will prevail and if you can exercise that, you will have a new FAVORITE gun. If not ... feel free to sell it to me. ;)

The slide stop could easily be a factor. Even if properly engaged at rest the explosion could be affecting the spring interaction with the slide stop if the milling of the Slide stop is not perfect. Also if the slide stop is slightly thicker at the part that engages the slide notch, it can be getting caught up and locking back. I HAVE had this scenario.

You did better than me. I asked for a spring and they said I only need the slide stop. I will also post when I get the part and test it at the range. It would be helpful to others to have a known solution to this problem.

I received a new slide stop and slide stop spring from Kahr today in a small padded envelope. It took about 25 minutes for installing them and adding some more TW-25 B lube on the internal parts while it was apart. I see no differences between the old and new parts, and no apparent differences in the way they all interact.
Of course, live fire at the range will tell the story.
And yes, the small flat head torx screw that holds the slide stop spring in place needs a T-6 torx bit for the spring change. I did take the fine file to the sharp corner of the slide stop where it engages the notch in the slide and add a little chamfer.
And that slide stop still may get some Bridgeport machine time with a small tungsten carbide end mill so the top ledge on the slide stop isn't so close to the bottom of the rail on the slide. It must be a MIM part, it's pretty hard.

Just got back from the range. Replaced the slide lock with the one sent to me from Kahr and 100 out of 100 shots with no problems. This looks promissing, becasue in the previous 500 rounds I have fired, I had 2 to 3 failures per 100 rounds. I would like a second trip to the range with 100 by 100 sucess rate before I declare victory. If I continue to have success we can be pretty certain that this fixes the problem, although I could not tell the difference between the new slide lock and the old slide lock.
cee_Kamp
01-12-2013, 06:13 PM
I also just returned from the range with promising results, but not a complete victory.
I fired 200 rounds of Winchester White Box 115 gr. FMJ without a single malfunction.
And no particular attention where my thumbs were located on the gun when firing. This is great!
I then switched to the Remington 124 gr. Golden Saber P+ ammo.
I immediately had the malfunction with the slide locked back with the slide stop.
Several rounds later, another.
I then changed to an "aggressive" thumbs away from the left side of the MK-9 and finished the box of 25 rounds without any further issues.
So statistically, firing only 25 rounds of the premium SD ammo isn't sufficient.
But considering the price and availability of ammo recently, I'll continue with my testing when possible.
After returning from the range this evening, I cleaned the MK-9 completely and had the grips off for the first time. All the internal components looked great and the sliding wear points looked lightly polished. I now have about 500 rounds through the gun.
On a positive note, the frame seems perfect, without any of the defects shown in the posts & pictures about MK-9 and MK-40 "cracked frames" I've been seeing here in this Forum.

I forgot to mention while getting the Kahr MK-9 reliability figured out, that I stopped at my LGS last week. They had a mid 1970's Smith and Wesson model 36-2 "Chief's Special" in the handgun case for sale. While I am not a big fan of blued guns for carry or hunting in foul weather, this all steel pre-lock .38 special 5 shot "J" frame with forged color case hardened trigger and hammer will be going home with me on Monday. It's got the hammer mounted firing pin, not the frame mounted firing pin.
Bluing looks to be at about 97% with great timing and cylinder / crane lockup.

I think I got this problem for the slide lock locking back after 2 or 3 rounds fixed.
With the new slide lock, I just did another 100 rounds of American Eagle and 50 rounds of Winchester SD ammo. The gun is perfect. With the replacement slide lock from Kahr I have now shot 250 rounds with no failures, so I am pretty convinced this fixed the problem.
Unfortunately, I now have another problem. Every time I shoot I crack a follower on one of my magazines. I have 9 magazines. I do not think this is anything I am doing. Has anyone had problems with cracked followers?

Yep ... that's the deal. Ramp end of the barrel is hitting the mag. You will find this can also KEEP your slide from locking back on occasion because the barrel knocks the follower pin OFF of the slide stop.

Thanks, I called Kahr and they said send it back to them with the magazines that had cracked followers. They even supplied a prepaid FedEx label to send back to them. I am now waiting for them to repair and send back.

Finally...my Kahr is perfect! I had some problems with my new MK-40 Elite. First the slide would lock 2 or 3 times every 100 rounds after 2-3 bullets. Kahr sent me a new slide lock and that fixed that problem, it has not reoccured since I put in the new slide lock. Next, I would crack one or two magazine followers with every 100 rounds. For that Kahr said I needed to send the gun back to them. The good news is they sent me a prepaid label, paid shipping both ways, fixed the gun, replaced four folowlers....all for no charge. Other than my first bad experience with Kahr service, where the tech said the problem with the slice lock was my fault, every subsequent call to Kahr Service and they have been great. I shot 161 rounds today and the gun was PERFECT. I was able to place 98% of my shots in the inner two circles on the target. I am now happy with my MK40 Elite, and will use it regularly in a pocket holster as my carry gun.

Hal, fantastic that you are thrilled with your firearm, and thanks for reporting the great Kahr CS.
I found a LGS with two new and one used steel Kahrs (new MK9, K40 and a used MK9). Trying to decide now what (and how many) to add to my own collection. LOL

I am having the exact same problem on a brand new MK40. The first time I went to the range, I shot 240 rounds, and had three failures, exactly as you described. On the 2nd or 3rd bullet, the slide would lock back, like the magazine was empty, but there was three or four bullets still in. I pressed the slide stop down, and the gun fired the rest of the magazine fired ok. The second time I went to the range I fired 100 rounds on MY MK40 and had two failures. I fired 100 rounds from my Glock 21, with no problems. I am using American Eagle factory ammo, so I doubt it is the Ammo. It was suggest that my thumb was hitting the slide stop so the next time I was at the range a fired another 100 rounds with two failures. I was very careful with my grip and am sure it was not my grip causing the problem.
It has been suggested that it might be the slide stop spring but I have visually inspected it and it looks ok. I called Kahr service and was very disappointed with who I talked to. They offered no help and suggested it was my problem. I need this gun to work 100% of the time, because I bought it for Self Defense, but cannot use it for that if I am not 100% confident in its performance.
I am very happy with the gun, even at the third time at the range, it is reasonably accurate. I was able to get 96% of my shots in the inner two circles. I need to get more exprience with it, becasue I am use to Glocks, as I can usually get 98% if my shots in the inner circle on an NRA D-1 target with my Glock. But I need it to work 100% of the time.
I would appreciate know if you figure out what is causing your problem, or you get a better response from Kahr than I did.
You didnt happen to talk to Ian did you. I recently had the displeasure of dealing with him about the crappy wood grips they sent me and along withbeing unwilling to help in any way, he was also very rude.
I hope i never have any more problems cause from what i have seen kahrs customer service succcckkkkkkssss

I do not know who I talked to. The second and third person I talked to were very helpful. The first was not.
By the way, I also ordered the Grips and they did not fit. I was not hard to carve out 1/8" from the inside of the grip and they not fit perfectly and look great

Solved my Kahr MK-9 problem permanently. Sold it!!!
Kahr should be able to fix this problem for you, but it may take a while.
On 1/2/13 Kahr received my MK9 that I returned to them with a cracked frame, and I'm still waiting to get it back (with a new frame).
That is just totally unacceptable. Piss poor in fact.
