Do you store your spare magazines loaded (properly secured) or empty? Many keep them empty in order not to reduce the “spring” in the magazine spring. It makes sense. A compressed spring over time would naturally lose its original shape, right? Well, that thought has been a matter of long debate on popular sites.
Is it true? Do springs in ammunition magazines lose their tension if they are compressed for long periods of time? The best video I have found answering that question is on YouTube: Guns Up Review – Magazine Springs.
What is the answer? Succinctly, according to my research, a magazine manufactured by a reputable manufacturer stored in normal heat and moisture conditions will NOT result in the loss of magazine spring tension. Watch the video and consider for yourself.
