For 99% of you out there you have nothing to worry about. Also both of the mags were OD green. A chief I met up there at a leo shoot asked me how my OD green P mags were holding up. I had told him I had only used my black ones. He seemed to think that the color had something to do with it. I did not have time to go into more details with him. So in all I had two people talk to me about issues with P mags up there. One was Sean McGee the Chief of UAF PD and the other was Bill Filiaga the owner of Protec. A black rifle shop up there. Bill is a Master Class shooter in USPSA and a store owner. Great guy.

    Or you could just push the detent that allows the stock trigger guard to pivot out of the way.

    The people I have seen post up about it state that when it comes to lube, they run the weapon dry and CLEAN. (we all know dry and dirty won't work, but dry and clean does fine until it gets dirty).

    Well, at -40...I'm pretty sure my lips would "fail", too!

    No, it's not Fairbanks, AK cold where I live, but it will get -3 or -4 cold. Are pmags safe, or should I be using my C Products mags?

    Funny it only gets to -3 or -4 where I live. I live at the 41st parallel on the East side of the Wasatch front in Utah at 5100 feet. I grew up in Northern California at the 41st parallel at about 2500 feet and it would get to -15 in the mornings for a couple weeks during the winter.

    That's true about the trigger guard, but this is my grab and go gun, so it would be better to have a trigger guard that already accomodates the gloves without having to fold it out of the way. I can't say that I'm worried about my pmags breaking since it usually doesn't go below -25 or so and that's kind of rare.

    If its REAL cold - use arctic mitten over an anti-contact glove -- you flip off the arctic mit and use the glove for weapons manipulation.
    the 'Arctic' trigger guard is for morons.

    very light oil - sparingly.


    militec is like cement at low temp.

    The only time to be light on lube is in sub-freezing temperatures. Heavy lube in the desert is a good thing.

    PMags are fine for your conditions. Keep Alaskapopo's posts in context. He is describing a problem that has been demonstrated with one color of PMag in extremely adverse temperature conditions, over a sample size of 2. There are lots of people using PMags in very low temperatures- the fact that only a few people from a specific region have encountered the problem should be indicative of how obscure a problem it may be. Only when subjected to extremely low temperatures for extended periods of time do they suffer from potential feed-lip failure, as opposed to just about every other magazine which fail by simply dropping them on their feed-lips or actually using them.

    I would rather use a magazine that was a known inducer of ED than use CProducts mags for anything other than barrier testing ammo.

    Given a high quality carbine, there's nothing special to do for your environment. Changing the trigger guard may or may not be worthwhile.

    For winters in the Dakotas, there's no need to change from standard cleaning and lubrication norms. As always, use a high quality lubricant.

    As noted by others, if temps get really low (0 to -), I'd consider lightening up on the lube, but how much so depends on more variables.

    I am not sure and I believe more cold weather testing should be done. I plan on doing some this winter. It only gets about -5 or so here at the coldest. I live on the coast.

    I sincerely doubt the color of the mag has anything to do with the "problem." There is no problem until a real test with more than two mags is used. Of course if any of you have a scientific reason (the dye perhaps?) as to why the lips cracked, I'd love hear it.
