Thanks Witch Doctor! I fixed it too.

AFAIK early pmags used to have some issues

Interesting read.  I'm curious of what make/model rifles were used and their condition, as well as a photo of any used USGI mags that may have been used in those rifles.

I have a shit load of pmags and have never had any issues with them, even after dumping 15K through several of them combined.  A lot of these issues is people finger fucking the mags and over abusing them to the point where they exceed the product's limits.

That being said, I have pmags, USGI's, L5's and all the other CF's mags with no complaints.

YMMV, I have had problems with 2 of mine cracking.

It's interesting how all the mags in that thread have the exact same crack, going in the same direction.

I had this happening to one of my 10 Pmags.. it was a 30 rounds black windowed pmag.

A point of superglue when I saw the problem was enough to fix it and avoid futher damages. I've tried to broke it open again, but it's now rock solid:

This occurs most often when a magazine with 30 rounds (or worse 31) is slammed into a weapon with an open bolt, the feed lips don't like that.

In fact I can pretty much guarantee that any polymer magazine will have a crack in that area if you do that once or twice.

Just be diverse in your mag selection.  Pmags, Lancers, USGI's are in my inventory.  I don't like to put all my eggs in one basket.  The only mags that I have seen this happen to are the 07 batches.

Would that be harder on the mag than dropping it from shoulder high? I know  I have seen something like a drop test video where they came out all right. Does slamming the mag home with the bolt back just focus all you "ooomph" into one tiny place?

We did just about all of our origanal testing with p-mags and have never had any issues other than sticky finger sindrome.
As far as Im concerned Its the best mag in the industry bar-none.
I keep a loaded mag in my truck, its a p-mag the one next to my bed , Its a p-mag
The one in my desk drawer  YEP a P-Mag.

This may cause a problem...I don't know.  Magpul has stated that it was a problem in the molding process that has since been corrected.  All of my new production Pmags are GTG.  In my case, if the spine is going to crack, it will happen very early on without any kind of abuse.

first let me say I am far from  a PMag hater, I do like them and will continiue to buy them but I prefer USGI mags

I'm sure it is somewhat rare but I have been seeing more and more people posting problems and even if people are "finger fucking" their mags they still shouldn't crack from that.

Yes. I would expect a PMag to survive being dropped for quite a while.

The rounds want to keep going, the spring wants the rounds to keep going, the polymer flexes and eventually cracks.

Wait, you're not supposed to put a loaded mag in a gun with the bolt locked open?  Huh?

Just when i was finally going to pick up a couple of Pmags!

How are they even close to superior or even equal to a G.I. if you have to worry about slapping in a fully loaded mag

Can someone tell me what "fingering" is?

Finger fucking a mag is when people start pushing down on the follower and complaining that it is sticky or that the follower does not move smoothly.  If they would just use the mag, load it up with ammo and go to the range, they would see that the mag works perfectly.  Some people spend 11 hours a day groping the mags looking for defects and bitching because they saw a tooling or molding mark on the mag.

Finger Fucking a mag is a industry term..

ETA: As I mentioned before, I have several types of mags and my PMAGS are one of the best and reliable mags that I have.

Hey I'm not a Pmag hater-but I am too sceptital to just buy them just because every one loves them.

I've seen the videos of trucks,cars,dropped on concrete,in mud,etc.Its cool and all plus a GI couldnt do half of it(I freaked out once when my wife tossed a hatchet into a box full of colt mags certain she had to ding at least one)

Its just that every time I'm gonna buy a couple A post pops up about splits or cracks.

Great that you can run them over but I would think it better not worry about slapping in a mag and letting bolt strip of a round without cracking mag.Plus how the hell will fingering mag screw it up!?

The defective mags were traced to a bad batch of polymer from 7/07. Check the dates on your mags to see if it might be from this batch. If it this then I would probably relocate that mag for training/ranged use only just in case.
