PMag in prolonged loaded status

Magnumite · Jul 24, 2020

I have read the original PMAGs didn’t tolerate being stored loaded long term very well. I also understand the later generation mags are okay, even without the spring depressor clips. Is this correct?

What is the accurate assessment?

Can't tell you about early versions but they're now standard issue for the military. I would think they've been exhaustively tested to destruction to find out how durable they are.

Being standard military issue speaks droves. That is comforting to know. Thank you.

Gen 2 pmags ok? Or are the Gen 2's considered as the older version?

John from MD · Jul 24, 2020

I keep mine loaded to 28 rounds just in case.

Red1917 · Jul 24, 2020

I load them full and leave them in my bag for matches, gen 2 and 3s and never had an issue yet, had most of them for years at this point

I’ve got 7 Gen3 pmags that have been loaded since 2013 I think. I can’t say for sure that they will work since they’ve been stored, but they haven’t exploded yet.

If you're looking for a spring upgrade from what I understand the Tubb flatwire springs are more durable and take up less space. I think you can fit 33 rounds in a standard magazine as a result.

John from MD · Jul 24, 2020

That may well be true but they don't have the same amount of testing as the originals. Maybe if Uncle Sugar should buy some, we may find out.

I thought if you did not use the dust cover you should not leave them full loaded for long periods

jokie · Jul 29, 2020

I believe they say that because the dust cover also relieves pressure on the feed lips.

HappyCamper · Jul 29, 2020

I've got some that have been loaded with 29 rounds for at least 6 or 7 years, most without the dust cover. Can't say if that has had a negative effect, I suppose it's about time to go dig them up and find out. I hope I remember where I buried them...

I buy Daniel Defense 32 rounders and keep 30 just in case.

I've left gen 2 and gen 3s loaded for years and they work fine....probably gen 1s but cant say for sure

Beginning of this year(January) I found five original straight 20rd pmags I had packed away and forgot about. I know for a fact they have been loaded since January 2009. I fired the rounds out of two of them with no hiccups. I continued using them that range session with no issues. I know two mags isn’t a great test but it’s something. I still have three loaded and will take them to the range after the covid/elections.

Maybe I’ll start keeping only 99 in my Surefire so they’ll be sure to fire

That thing will give you a hernia. :lol:
