EDC Ammo maintenance and storage

[CurtisJ]

So I have been carrying for a little over a year, though only in the last 6 months have I switched from owb to aiwb. Usually in a kydex black point, but sometimes in a minimalist trigger guard clip. I can already see the toll it takes on the cleanliness of the gun to carry daily, T-shirt lint, dirt, etc. my question is more about ammo. How often do you change the ammo in your edc? I don’t unload it at night, I only unload when doing dry fire (once or twice a week tops) and even then I have separate magazines dedicated to practice so I am only cycling the 2 live rounds in and out of the chamber. I keep Federal 9mm HST in my carry and i can see some discoloration on the bullets that have been loaded and unloaded several times. Is mositure an issue? Should I be cycling to fresh ammo on the regular anyway? And last question, is there any problem with keeping a mag in the truck with this heat? Thanks for any advice
