I'll bet I watched a half dozen YouTube videos on this. One guy left a Pmag loaded for several years without the dust cover and it shot fine. Another YouTuber stated that if you store Pmags loaded the lips might crack if you don't store them with the dust/impact covers. The main issue supposedly is tension on the plastic feed lips over time. The dust covers are supposed to mitigate this. I gotta be honest: from my join date until today I hesitated trusting Pmags as anything but every day range mags because of differing opinions on subjects like this. I don't wanna Google it (again) and get 87 different opinions. Once and for all: If one were to store 30-round Pmags loaded, whether filled to capacity or downloaded a tad--does one need to use the impact/dust covers to keep the tension off the feed lips? |

I can’t give you a definitive, scientific answer. Al I can say is that I have Gen 1 PMags (pre-dust cover, pre-updates, etc.) that have been loaded to 30 rounds since 2008 and there is no sign of cracking feed lips. I’m not sure why I’ve never shot these, but it’s probably because it became a novelty to me to keep them loaded as the new generations were released and I amassed a quantity of those because they were so economical to buy. Now I haven’t put them under a microscope to check for micro fractures or anything, but I have unloaded and reloaded them occasionally and none of the feed lips broke off and the springs appeared to just work fine and expand as expected. Again, not scientific, just my own experience. |
