Dumbest question of the month or possibly year

[Dvrjon]

Iv had some loaded to 28 since 2010. The lips have not cracked but the bodies have flexed. They no longer drop free from the magwell. You must manually strip them. Mags stored out of state, and were re acquired thanks to Mr Benitez.

What Gen PMag are they?

The Gen 2 and Gen 3 PMags seem to be thicker, made from a different polymer and structured to provide more support.

Yes, I had one PMAG crack. It was a Gen 2 sans dust cover. It had been stored loaded for maybe six months after only using it a few times. The crack was on the edge between the feed lips. Only one out of - well, let's just say a lot. I've had other PMAGs stored for years loaded and they're fine. I am constantly cycling through them all over time.

I personally like the gen 3 PMAGs, but honestly, I'm not sure why.

Anyone ever see PMAG's crack from being stored loaded (feed lips) ? I know AL GI mags 20, 30 will function like new after they get stored loaded for at least 20 years but what about that PMAG plastic under tension?
