The Importance of Magazine Rotation

Magazine rotation? Yes, like any mechanical device, a magazine is prone to wear. Particularly, if loaded consistently, the springs can soften and eventually lead to a failure to feed. In turn, itís important to give the magazines a rest and call a fresh one into action. Firearms instructor and member of Colt Combat Unit Ken Hackathorn goes over a simple magazine rotation system...

Do Loaded Magazines Wear Out Magazine Springs?
https://www.luckygunner.com/lounge/m...-ammo-cycling/

Two key Terms to understand with respect to magazine or other springs...

1. Spring fatigue
Spring fatigue occurs when a spring has been repeatedly compressed and returned to rest. Basically, fatigue is the eventual loss in some spring stiffness and force or metal fatique failure (breakage) because of repeated use.

2. Spring creep
Spring creep describes a springís permanent loss of stiffness from substained compression over a period of time.

E.G.: Take two brand new magazine springs for any semiauto; measure them, photograph them, put one in a magazine, fully load the magazine, put it in a drawer for a month...
Unload that mag, pull out the spring and measure and photograph it against the unused spring...
There will be a visible difference between the two...
Too much of a difference to ignore...
You can add a 3rd test by using a 3rd new mag spring and load, fire, repeat several hundred rounds and disasemble and measure & photograph the 3 springs...
The fully loaded, but unused magazine spring will be the shortest of the 3 by far...
Does not seem to matter whose magazine springs they are, the result is the same, long gun, shot gun, handgun.

To paraphrase Forest Gump... Magazines are like a box of Chocolates, you never know what you're going to get or how long they will last even from the same manufacturer.

Some folks will go their whole lives without a semiauto fail to feed which may or may not be due to magazine spring weakness. I'm not one of those people. No matter how fast you can recover from a fail to feed, that may be time you do not have to spare.

For home defense & hunting I prefer revolvers to eliminate the possibility of a magazine spring failure and or a fail to feed a problem unique to semiautomatic firearms.
With respect to hunting it's for bear defense mostly or when I don't have a chance to use a rifle. Like fishing in Alaska.

For EDC CCW I'm a semi auto guy, and rotate my magazines daily.

Spring fatigue? My stepson has a 1911 that was made in 1938. It was given to him by his grandfather a few years ago before his death. He got it issued to him in the Korean war. The magazines had never been unloaded since 1951. We took it to the range and the firearm fired and cycle flawlessly with ammo head stamp from 1943.. sorry, I just don't buy into that whole line of spring fatigue. I've never seen it happen although it might personally I'm not too concerned with it

He's claiming that most LE rotate mags every 90 days? I call BS.

I don't discount the fact that there is SOME compression from loaded mags. My old mags are easier to load than brand new ones. I do question whether the compression is of any amount that matters. My own experience with GLOCK mags has been that in 21 years I've never had a FTF due to a mag spring.

Physics is physics and I get that metal does indeed fatigue. However, after spending time in the real world with real magazines (among other mechanical gadgets) and seeing how things actually work, I'm not worried about it. One mag may be different from the next and one may wear out while another doesn't. Different batches of metal, hell, maybe different humidity that day at the plant. I dunno. I have original mags that are over 25 years old and have never failed. I have brand new mags that have failed to feed.

At the end of the day, I'll run what I brung and practice mag failure/failure to feed/failure to fire drills/failure to eject. It will be a really bad day when I actually need it and it fails but I'm not entirely sure that's a preventable thing. Mechanical devices fail. It happens. In the word of E. Shell: Pass me another mag and keep shooting.

FWIW, I PCS'ed (Military Transfer) and left a Beretta 92 at my Dad's house. It sat with two magazines fully loaded for almost 9 years. When I finally picked it back up, it functioned flawlessly and now 20+ years later those magazines still work just fine with the original springs.

Magazine rotation/spring compression has been discussed in the past. This is not a new issue.
