YES. In here is just one great example: http://mcb-homis.com/magspring/ THIS IS WHAT I DO: I don’t keep a tight schedule. I do keep a couple mags for each weapon loaded all the time, and when I go to the range I bring them back empty and rotate them out with other mags that have been sitting empty. So none of my mags sit loaded for more than a few months. I also don’t load them up all the way. (I have brand new mags for some of my rifles that never get used. They are “extras”). I clean and lube my mags after firing too.

    We actually just had this problem. We just took over the AO from the 101st and alot of our guys got mags from them and never swapped out mags just kept their old ones. Well alot of them didn’t feed a simple fix would be to slap the bottom of the mag but even still in a combat situation thats not good. So like ReaganMarine stated it depends on the manufacture and quality of build and parts. Why take the chance ?

    I thought I’d chime in here.This is somewhat of a variable discussion/argument. In my other “hobby” I’m an avid hardcore drag racer. It’s common knowledge in that arena that camshaft spring design and material and even shape has a HUGE effect on performance. H11 tool steel and other ‘exotic’ metals are all the rage in valve spring design for ultra high-rpm,high horsepower race engines. I know absolutely,without a doubt,from experience that if you don’t loosen the rocker arms off of the valve springs that are under compression and therefore relieving the compression tension during winter storage,they could be ruined over the winter. Now. Material design plays a major part in this. The ‘cheaper’ metal in ‘cheaper/inferior’ valve springs will without a doubt be ruined after staying under compression that long. The high $$$$$ stuff has less of a chance for that to happen because of quality materials but why take the risk? BTW Robert, I do not leave the weight of the car on my springs over ther winter either;I put it on jackstands on all four corners,and take the wheel/tire combo off for seperate storage. Now,applying that same concept to firearm magazine spring design. I know that spring design and materials used are far more advanced than years gone by,even for something as simple as a magazine spring, this is true. But,ANY metal can loose tension after being under continual compression for long periods of time. The better quality metal the longer it can be under tension and not go bad,but why take the chance. I rotate mine every 30 days or so and do a -1 on capacity so as not to have coil bind. I’m not rich by any standard so my mags have to last as long as possible and this is my method.

    This is classic example of internet rumors.

    Modern magazine springs from reputable manufacturers can be loaded for many years without issue. As the head of a firearms training unit for a large police agency, I have our troops keep all magazine loaded in all their weapons all the time. The only issues I’ve seen over the years are companies that use inferior magazine springs like older GI 1911 mags, Smith and Wesson pre 1990’s magazines, and cheap imports.

    Many of our USGI M16 mags have been loaded since the 1970’s. Beretta mags since the late 1990’s, and Glock mags since the early 1990’s, they get cycled during training and qualification but are always loaded. No problems with spring failure or spring tension.
