Another nosediving question

[HJHMD]

Hello everyone,
I have another nosediving question. I have done a search and read about the nosediving issues. My issue is as follows: When I swap out magazines, occasionally the first round will nose dive and I have to take out the magazine reposition the round and try again. This is not very comforting for a self defense weapon. I am very meticulous about loading the magazines carefully ensuring that the rounds are properly seated and that the top round is well placed. I chamber the first round in the new magazine from slide lock using the slide lock release lever as Kahr recommends. Any thoughts on why this is happening and how to remedy it ? Thanks in advance for your help.

Try different ammo, I'm having the best luck with Winchester PDX1 (147gr or 124gr, doesn't matter).

Other things to consider:

How many rounds are through the gun?
- Not many? Might need more break-in.
- A lot? Might need a new recoil spring.

Try polishing the feed ramp.

+1 on trying different ammo. Mine will nosedive when using hornady critical defense 115gr

I personally don't think you need to try different ammo. This weapon should be able to feed any round when used as designed. You are releasing the slide using the slide release as the manual states. It should feed the round reliably.

One thing I would double check is that the magazine spring is intalled correctly.

Another thing to check is if the inside of the slide release is coming into contact with the round when you are trying to chamber.

Another member with a nosedive issues sent their CM9 to Kahr and they trimmed the recoil spring. This would be a 'last resort' type of fix.

Could be a few things, some of which can be eliminated as you tell us more about your gun and experience.

Nose dives can be caused by the slide not having the designed force to push the round past the sticky point on the ramp; and/or an unpolished or dirty ramp; or magazine issues.

If your gun is still in break-in stage, I'd first consider the slide force issue. Break-in causes a lot of friction and demands proper lube and grease to reduce friction allowing the slide to move freely. Also, the ramp needs to shine when clean and a little lube rubbed into it.

Read and follow the Proper Prep guide in the Kahr-Tech section and lube according to the lube chart, with special attention to lube point 6 - a high friction point. Lightly grease the metal rails in the frame top and bottom with a Q-Tip or similar. This should help the slide and ramp part of the equation.

Next, use round nose factory ammo for break-in, at least until it straightens out. The slide needs a good ammo to really slam it back and rebound forward. Target reloads may not hack it to begin with. NOTE: once broken-in, the friction is way down and it should take most if not all factory ammo, and target reloads are fine.

After trying this please come back and let us know how it goes. We have more but this will hopefully get you going.

Ressom,

One thing I would double check is that the magazine spring is intalled correctly.

The magazines are factory mags, I haven't taken them apart.


Another thing to check is if the inside of the slide release is coming into contact with the round when you are trying to chamber.

I don't know how to do this , help.

Further info: I have about 3-400 rounds through the gun. I did do the Kahr Tech prep prior to taking it out the first time. I am pretty good about cleaning and lubing but have not been lubing the feed ramp. I don't know how to properly polish the feed ramp, any
advice on that ?
Thanks for all the advice guys, what a great forum !

the magazine that is causing the nosedives, make a notation in ur mind as to what round it is always causing it at to. I doubt if it is an ammo thing.If ur chambering the first round with the slide lock lever kand it feeds Ok and then the next round is nose diving, it could be a follower issue. If u will go to the kahr tech section and hit on the propper prepping of ur new kahr and scroll on down it will tell u how to look for this issue. It is a fixaable thing, very easy to trouble shoot also. Polishing the feed ramp is a no brainer. If u can get some fine 600+ auto sand paper, u can polish that ramp to a mirror finish and not harm a damn thing. If u have a dremel, then with some flitz or mothers polishing compound and a dremel cotton cone tip, u can do thesame thing only alot faster. Normally kahr feed ramps are super out of the box. The proper prepping thread also will tell u how to see if u have rounds hitting the slide lock lever. again an easy thing to diagnose and a simple fix if that is the issue...

If u had a bad magazine spring, I would think it would duplicate your issue more often to, also same thing with the slide lock lever hitting the round on the inside. Make a notation in ur mind of what brand of ammo is also causing this issue. some bullets tend to get very close to the inside of the slide lock lever. It is OK if they are close but they should not touch that lever. Again a correctable thing..

If it's the 7 round magazine that's an easy fix - send it to Kahr with a note saying you'd like to swap it for a 6 round magazine.

yup forgot top ask that!! good man!!

I have had a few magazines in the past. That the feed lips (curved portion at the top of the mag) needed to be adjusted.
You can do google a google search for adjusting feed lips. To learn more about it.
It can cause the bullet to enter too high, or too low.

I bet a lot of these nosedives would not occur if people would tap their full mags on the back side. If all the ammo is not seated against the back of the mag after loading it up, a nosedive is way more likely to occur. Never had a nosedive since I started doing this. Even in my 7 rounder.
