Any issue storing ammo in spare magazines?

I keep a couple extra 9mm magazines loaded for my home defense pistol. I don’t store them in the gun and the rounds haven’t been chambered ever. Is there anything I should do to ensure that if I ever need to use them there wouldn’t be any issues? There’s no do-overs if they’d ever get called into duty. via /r/CCW https://ift.tt/3mTFZgJ
