    P Mag problem in cold weather.

    I just got back from a 3 gun shoot in Fairbanks Alaska. I like P mags and was talking to one of the shop owners up there who was at the shoot. He showed me 2 P mags with busted feed lips. He said they got broken in -40 below weather. I grew up in Fairbanks and I have seen it -60. I also know how hard cold weather is on plastics in general. This is a concern for anyone using P mags in sub 0 weather. I intended to keep all 45 of my P Mags as it does not get that cold in the southern part of the state. But my go to mags in the winter are going to remain HK. I hope MagPul can get this issued worked out. The shop owner is going to bring the mags to the next shot show. I am a huge P Mag fan but this is an area of concern for me. It is not going to be a concern for most of you down in the lower 48.

    Hmmm... that is good info. Don't think I'll ditch my P-mags, as I live in Idaho, but It does get cold in the mountains here. I wonder what the threshold for risk of breakage is. Anything below 0 deg? -20 deg?

    Perhaps Drake or NickB will chime in?

    -60 wow. I think everything man made has its temperature limits. I missed cold weather training in my unit years ago. I do remember everyone switching from CLP to LSA for the weapons. I wonder how anything works including humans in -60 degrees. I can't image that type of cold. David

    We're lucky if it gets down to 40 above here!

    "I hope MagPul can get this issued worked out. The shop owner is going to bring the mags to the next shot show."


    First off. do we know this to be the issue? for sure

    did they crack when dropped loaded in the cold. how did they crack

    I have run mine pretty hard down to -10 then with windchill a bit more.


    why wait till shot show why not send them back? or call magpul if he hasnt done so

    i know anything is possible we need abit more info here.

    To me, this is a non issue.

    What kind of fighting is realistic in 40 below weather anyway?

    This is all true. The shop owner might have had the early gen I's.

    Tech Expos, SS, etc are generally the worst place to contact a manufacturer about a problem (as they are very busy). Much better to call them.

    Pat, I would not keep HK as my "Go To Mag." They have all sorts of fleas and while they may work right now, once their springs become weaker, they will not feed. They are also heavy, will rust and generally do not do well in SBR's (even when new). There is a GEN II version out to fix some of these issues, but do not think it has really fixes anything.

    If you need an a trusted mag, NHMTG or BCM with Magpul followers is the best game in town (for alum.).

    Wind chill is a "felt" temperature on skin. A PMag in -10 deg F conditions is still -10 deg F regardless of the wind chill factor.
