Went through some mags I've left loaded a few years
2 or 3 windowed pmags you have to force into the magwell
And of course won't drop free.
1 non windowed- same same.
I unloaded them and they're still stretched. I think they're gen 3
I noticed on my Aug pmags there's a re-enforcing rib near the top that runs horizontally. Hopefully I won't have the same issue.
FWIW my 40rd pmags are fine and drop free fast
