Perhaps you’re worried too much. Ammunitiontogo.com tested various mag springs and found all the tested mags worked well after 270 cycles (equal to 8,000 rounds through a PMag). They also had a lab cycle the springs on a Glock 17 mag and a 30-round PMag until the springs failed—over 250,000 round equivalent for the Glock mag and over two million through a Gen3 PMag.
Of course there other reasons for a mag to fail, but this should put to rest any concerns about long term storage of loaded mags. I’ve only touched on the results and recommend reading the article for yourself.
