So, using your magazines is the only thing that really wears them out
BLUF
Conclusions
Common wear and tear from everyday use is more likely to degrade the overall quality of a firearm magazine than the spring failing on its own from being loaded to full capacity and stored for long periods of time.
Since it’s not economical for a shooter to monitor their spring’s quality with force gauges, the only true way of knowing if your magazines are functioning reliably is from actual use during training.
So, unless you’re part of the group of individuals that actually shoots thousands of rounds down range on a weekly basis for training or completion reasons, the whole issue of worrying about the lifespan of your magazine springs is somewhat trivial.
Other, Larger Concerns
If you’re prepping for a SHTF situation, simply load your mags and set them aside. You can now use all the extra spare time figuring out if you want a Menu 18 beef patty or Menu 14 Spicy Penne Pasta MRE!
As for mags, there are many other factors to consider before worrying about magazine spring failure. First, address the overall quality and cleanliness of your firearm, magazine housing, guide rod, buffer tube spring, ammunition choice, the list goes on. Magazine springs are relatively cheap items that can ultimately fail, just like any other man-made item before it. Luckily, they are easy to replace once identified as the cause of a malfunction.

A massive gun magazine stress test to determine how long magazine springs will last and if we can determine outside variables that impact their longevity.
We set out to test magazines. How long do they last and what can you do as a shooter to help ensure they’ll function properly for as long as possible? In this project, we’re going to give the quick answers up front and then we’ll dive into some of the details about our testing protocol and what we learned.
Spring Test Summary
For about a year, we loaded, unloaded, and function tested thirteen different magazines.
