What Weakens, And Doesn’t Weaken, A Magazine Spring

Modern magazine springs are manufactured to maintain their function under stress. In other words, they’re meant to be fully compressed when the magazine is fully loaded. If you were to load a brand new magazine to it’s capacity and let it sit in that condition for years, it should be absolutely fine.

If course, there are outside elements that could play into the longevity of the spring. Corrosion, debris, moisture to name a few. With these factors, the lifespan and/or intended function of a spring is always up in the air. But if kept away from these elements, it’s function shouldn’t change all that much.

[*** On the other hand, loading and unloading a magazine will degrade the spring’s usefulness over time. ***] There is no real rule of thumb when it comes to this, so it’s always best to maintain good practices with your magazine springs just as you would your firearm.

A modern magazine should be able to handle tens of thousands of cycles, but with anything, your mileage may vary.
