Keep one magazine loaded or rotate mags every so often? I have found through many years of experience that one should rotate magazines around once every two weeks. Constant compression does not weaken the spring however daily rotation will due to the compression/decompression. Just take a paper clip for example; bend it once and it will not break--constantly bend it back and forth and it will snap eventually. (Not comparing the mag spring to a paper clip by any means; just using it as a visual) I would like to get some feedback from you on this topic. Thanks.
