    I agree more tests need to be ran. Until they are though my winter carry mags will not be P Mags.

    Good God, man. How many threads can you work this comment in to? We've done cold weather function testing, and the PMAG passes just fine. The only failures we've seen were fully loaded drop tests on the feed lips under circumstances that also make aluminum mags fail.

    I'm sending you some magazines so you can test for yourself. Post the results. I would be very surprised if you can replicate the failures your friend experienced by simply inserting the magazine into the mag well, but maybe I'll eat my words...who knows.

    It would be nice to see some actual documented testing instead of of "I know this guy and he had two PMags break so I can't recommend them for extreme cold weather" inserted into threads about PMags ad nauseum.

    You know...
    I think that in certain Oklahoma weather conditions, such as...um...tornadoes, yeah, during tornadoes Pmag lips fail due to drastic changes in atmospheric pressure. That's right, during tornadic weather events, baroflux renders Pmags useless for reliable defensive purposes. As an engineer living in Tornado Alley, I feel uniquely qualified to test this phenomenon further across the full spectrum of the Fujita Scale of Tornado Intensity. I hypothosize that failure rates will increase exponentially as the intensity increases from F1 to F5. If you'll kindly send me an test sample of adequate size and variety, I'll store them away and wait for a tornado to pop up to provide the appropriate test conditions. On second thought, send two groups, and I'll store one and use the other heavily, to see if degredation over time and use has an effect on the suceptibility of Pmag feed lips to cracking under tornadic baroflux.

    Mine too.

    I also have a theory that P-mags won't work after being thrown in an oven set on broil.... Care to donate to the cause for testing nick?

    Thanks I will test them Also don't take this as a hit I love P Mags I am just concerned about this issue. Also this thread was about winter ready M4's so I feel its a valid concern.

    I saw them with my own eyes and I have given Mag Pull his contact information. Not sure how much more I can do to help them out on correcting this issue other than testing them myself which I will be doing as soon as we get a cold snap.

    Well, I have no idea if this applies to PMags or not but color certainly plays a role in durability with Bulgarian waffle AK magazines. The black mags are much much more durable than the clear/smoke magazines. I'm not saying this applies to PMags, not by any stretch but it has applied to other polymer magazines before.

    yes extensive testing is NEEDED!!!! also i hypothesize that flooding can cause problems with both the moe forearm and the moe BUIS. As a responsible manufacture you really should send some one in Iowa at least one of each of these.... perhaps me??
