new cm40 follower destroyed

[jocko]

I doubt

It seems as of late there are more follower issues. Maybe there is something wrong with their injection mold. I had this issue in our business with some plastic parts. We had a mold that made 4 parts at the same time and after a while we were getting some failures (close to 25%). One of the cavities on the mold was messed up, so we stopped using parts from that cavity until we could make a new mold.

it IMO. the 40 cal kahr polymers are causing this issue far far more than the 9 and 45 combined. Kahr has asked when sending a gun back for the followers and magazines to be included, so again who knows. They are certtainly not gonna tell us what is going on, which is understandable to. We might not like that but most industries are not gonna tell you

This has to revolve around the barrels feed ramp being to close to the mag follower as the pistol starts to cycle a round out. Is there a point with the 45's where this started happening , are older 40's seem to have the problem My 40 is 1 year a 6 weeks old and no contact with the followers.

u got a point a few years bazck we did not hear of this happening, or at least it was so rare of an event that we paid no attetion to it.

i believe you guys are correct about barrel hitting. i keep all my brass and just thought to look and see if there were any marks on them, every case has two rough scratches from front to rim got the calipers out and their basically the same width of the feed ramp.

[jocko]

I am trying to picture what u said and I just cannot picture that or see how that can actually happen. If it sitting in the magazine the bullet has to be exposed to the feed ramp and IMO not the actual casing, and once in the chamber and fired. the feed ramp now has nuttin to do with extraction.

I would certainly stand corrected on this but I am just mystified to see how this could be happening. Maybe I am missing the obvious. any chance of showing us a photo.

My thoughts are this to. Once that casing gets up behind that extractor as the slide is starting to close and actually feed the round in the chamber, I would guess the bottom of the feed ramp would come into play/contact with the brass, as the slide is slammig that round in the chamber being guided by the feed ramp and possably feed ramp marks could be left on the brass casng.this if Iam correct is probably normal.. The feed ramp is what it is, it guides the round into the chamber.

Has anyone posted some quality photos of broken followers?? Is the ramp breaking or sticking the followers right around the metal area on the followers.

It looks like the bottom left edge of the barrels feed ramp was not gound off to a certain lenght it would hit and break the follower. Inserting an empty mag slowly with the slide back will show how closely the ramp comes to the follower.

Of my 3 kahrs my 2008 cw9 is the closest with only about 18ths gap. That ain't much, about two pieces of quality printer paper. But it has not hit. My 40 is closer to 28ths. Useing some very old feeler gauges. Seems like a couple minutes with a diamond stone on that longest corner of the ramp . I could also be very wrong sence I have not seen one broken. Who has a photos??

I've seen a couple of bad photos that basically show the front leg of the follower snapped off, but that is about it. Better and more photos would certainly help. If the feed ramp is actually hitting the plastic, there should be some kind of mark or damage where it hits. A good photo would show that.

[hardluk1]

I would think it must take a build up of strikes to do the damage so maybe someone will come up with one thats marked or cracked but in pieces.

LorenzoB is spot on about the front leg being snapped off.
Here's a photo that was posted by David the Gnome on TFL:

While there looks to be little or no mark on that follower, the gent (Caver60 on Glock Talk) that came up with the fix for the feed ramp stated: "But I'd stick a new follower in and after firing a magazine of ammo there would be a big scar where the feed ramp was striking the follower."
I had linked to some other of his info back in 2010, but that info is no longer available on GT. However, there are some more photos of broken followers available on that thread: http://www.kahrtalk.com/showthread.php?t=1778).

I would think it most take a build up of strikes to do the damage so maybe someone will come up with one thats marked or cracked but in pieces.

From what I've gathered, it appears to me that the follower can break with a single hit or from repeated strikes (I've broken that leg off and, though the circumstances don't really apply to this discussion, neither was significantly marked).

gb In that photo there looks to be a strike mark, rolled edge with dimple, just above the metal piece on the follower on the radius. If so that could only be made with one round still in the mag.

[jascott]
