NOSEDIVES - my take on it

[JERRY]

i havent had a malfunction with my 6 or 7 round pm9 magazines.....i think if i do i wont muck around with trying to make crap into a rose....i will just buy new magazines.

that said, if your current magazines have worked all along and all of a sudden give you propblems id say just change out the spring.

Testing is still in the infancy, but I will be giving cut down springs a go (thanks for reinforcing that). As to the 6 round mag, I don't have a CM/PM Kahr so I won't be venturing into that water.

My cw9 is cut down to a covert; I run a 6 round mag and 7 rounders with spacers. I can mess around with the 6 rounder if it'll help. Steve

That really would help Steve!
Thank you from all of us pm/cm shooters

The second round in my 8-round mag just hasn't risen up to the same position the first round was and allowing the slide to pick it up consequently the slide will lock back (open) a couple of times recently. Kind of like that second round was a micro fraction longer than the rest and wedged cross-wise in the mag and wouldn't rise up into position. Changed out that round and everything was smooth after that. Is this what's considered a nose-dive?

Cutting down mag spring...

Of course I've read all the theories on why the kahrs are subject to nosediving rounds, especially on the 9mm 7 rd mags. After having worked on it for awhile, I believe I found the exact problem, and is exactly opposite of what everyone thinks.
The problem is excessive mag spring pressure.
When the mag is full, the rims want to lock from the angle and excessive pressure. Basically when the stripper rail comes forward to pick up the round, the rim holds fast to the indent(don't know the technical name) on the rim below it, and the round rotates downward before the rims unlock. There's the nosedive.
Hold a full mag in your hand, push the top round out by the top rear of the round (where the stripper impacts the round), you'll see what I mean.
I solved mine by shortening my mag springs by 1 complete coil. The rounds strip much more smoothly, and I've had ZERO issues over hundred of rounds.
Of course this is all my own experiences, but I believe it is correct. Thoughts? Steve

Steve,

Would you post a photo of your "cut-down" mag spring? I'd like to try it but I don't want to cut in the wrong place.

SixPack, read this post about mags and mag springs for information.

This is about 8 round mags but the spring problem is the same.

My CW45 would not feed from the 7 round extended magazine. The first 3 or 4 bullets usually nosedived or once in awhile would stick straight up. Once I got down to the last 3 or 4 cartridges the mag fed fine.
Just thought I'd thow that out there in case it helped anyone figure things out.
