    Full Mags Wear Out Springs?

    I've heard a couple times that keeping your magazines loaded to full capacity for a prolonged period of time weakens the magazine's springs and therefore can lead to failures when in use.

    Is there any truth to that? If anyone has a link to an article/study, it would make for an interesting read...

    Popular opinion is full mags do not wear springs. the repeated compressing and release does wear on them.

    I have no link to hand but we had a fairly exhaustive thread on this a while ago. Maybe a search on ''mag springs'' could yield success.... and that tried on Google might yield even more from other forums too.

    Most reckon these days spring materials are that good that it will not be a significant problem. That said I suspect many of us do ''rotate'' our carry mags ... as it is a simple thing to do and maybe leaves us feeling better

    Over compression can hurt springs but mag springs are made to take full load anyways - and it is perhaps actual cycling of a spring that ''tires'' it quicker, as in recoil springs.

    Yep. It doesn't matter how long the spring remains in the compressed state; only the initial force used to compress it was applied to it. There is no additional force applied over time, so it stands to reason that so long as the initial force was within the limit of the elastic properties of the spring, it will return to 100% length, time after time, until it work hardens and loses elasticity.

    Loaded mags have been found dating back to WWII. Even though compressed for that long they still worked.

    Thats kind of like saying a car sitting for ten years that hasn't been driven wears the shocks out. Springs are designed to be either compressed or not compressed. I agree its the constant change of tension that wears them.

    Fired a Glock 19 mag last month that had been loaded for the past 10 years. Found it in an old assault vest I had stored in the atic and forgot about. Not a glitch and every round loaded fine.

    A car that sat for 10 years may very well need new shocks, but it's not because the dampers wore out - the rubber seals, wipers, gaskets, and boots rotted and let the pressurized gas/oil leak out. But, you knew this.

    I had heard that too but the guys that were telling me about it happened to be dealing with very old magazines. I am talking WWI era Lugers and 1911s. If there really was an issue that was not specific to these guys I would imagine improvements in metallurgy in the last century have resolved it.

    My Dad was a WWII Naval aviator. On the 50th anniversary of his discharge from the Naval Reserve, (Sept. '46) we fired off a mag of 45acp he had loaded during the Phillipine Campaign. (mid '44 I believe) Not a glitch, made some cans dance nicely. I've got the second one that God willing my son and I will run through in 2046. Both clips are going through my great uncles 1911A1 that he carried across Africa, & Italy following General Patton.(he said everyone followed Patton, the General led from the front!) My nephew borrowed the 1911A1 from me for tank duty in the first Gulf war. My cousin flew chopers in 'Nam with the same .45. It is a privilage to be the caretaker of this Colt Luteai

    When I was in the USMC (Dept of Navy) we were told to load the Colt M-16 A1 mags two rounds down. 18 rds for 20 rd. mag and 28 rds for 30 rd mag.

    WW 2 Mag

    I've got a Thompson mag that has been loaded since it was returned from the war, as near as can be determined. The steel cased ammo is dated 1942. Just waiting on a Thompson to come in to the gunshop to test it.
