How long is to long to rotate a mag. ?

Depends on the enviroment the mag is kept in.
If it gets dirty, dusty, or damp it will need to be maintained. Otherwise you can leave it loaded.
Springs only wear from repeated compression & decompression.

How long do you rotate the condom in your wallet?
Thats how ridiculous your question is.

Thanks Salty. I probably could have worded it differently. What I was getting at was the long term effectiveness, ( or failure) of the spring after being compressed for months. Typically when a semi is screwing up it's not the gun but the mag............................

How long is to long to keep a mag full of rounds ? How often do you guys rotate ?![[hmmm]](/xen/styles/default/xenforo/smilies.vb/009.gif "Hmm [hmmm]")
If you have to ask, you're not shooting enough. Go practice more. Your gun, your mags, and your skillset will thank you.
Rotate your pistol magazines

There are some truths and some misconceptions about the durability of pistol magazines. It would seem that everyone has an opinion, but most are based upon conjecture and not science.
The truth is that modern magazines and their related components are the best that they have ever been. Having said that, all officers must understand that magazines are mechanical devices and as such, are subject to wear, tear, and breakage. The weakest link in any semi automatic feeding system is the magazine. Most frequently issues with feeding reliability are as a direct result of spring tension within the magazine.
Magazines left loaded for long periods of time are subject to spring set, which equates to a lack of upward pressure on cartridges stored, as the weapon cycles. Having said all of that, I have found an easy fix that I teach my students. For any given pistol, I recommend ownership of a minimum of nine (9) magazines. Three will be carried daily, three will be at ‘rest’ left unloaded and three will be dedicated as range only magazines. I typically tell my students to mark the base plate of their range magazines with a dab of bright nail polish, so that the magazines that are dropped, kicked, stepped on and dirty never get mixed in with duty magazines. That leaves us with six additional magazines.
My recommendation is that when your duty ammunition is fired or turned in at requalification time, your fresh ammunition draw is then loaded in to the magazines that have remained empty during the last cycle. Then the magazines most recently left loaded are placed in a ‘rest’ mode until the next cycle. Over the last twenty plus years of firearm training, I have found this technique to be the very best at eliminating magazine issues.
Just found this. No mention of condoms........................

Do you think the coil spring on a car's suspension will be more quickly worn out by sitting in a showroom floor for it's entire life, or if the car is driven daily? Maybe that John L Carp fella knows what he's talking about, but from everything I've researched, coil-type springs lose compressive strength by being constantly compressed and released. I wish I could find the article containing info about a WWII 1911 magazine that sat fully loaded in a bedside drawer for 50+ years, and was inserted into a handgun, fired and functioned flawlessly.

In my archives (Email) I have a msg from LTC Chuck Santose who served in Vietnam. He found some fully loaded AR mags in one of his duffel bags. After almost 40 years, he fired them with absolutely no problem at all.
45Collector is right, staying compressed or at rest the springs will last damn near forever. It's the constant compression/decompression that kills them.

Condom do have expiration date. Make sure you do rotate it before expired.![[laugh]](/xen/styles/default/xenforo/smilies.vb/012.gif "Laugh [laugh]")
Actually, a wallet's tenancy to flatten your condoms is a really bad thing. Keep your condoms in a cool, dry place where your roommates cant find and steal them.
OTSO mags, you don't have to rotate. Find your best, most reliable mag, and carry that.
Oh, I see the issue. FIFY:
"How long is to long to keep a clip full of rounds ?"
Should be fine 'til I die.

Every six months I make sure to carefully spin each and every cartridge that I own, so that the gun powder doesn't get bunched up on one side. I am considering getting a bunch of those 7-11 hot dog rollers to do this for me automatically.
The centerfire stuff is time consuming, but the bulk packs of rimfire are just a bitch.

I do the same thing!!! I do it the same weekend I change the air in my tires.
Duty mags were kept loaded for 7 years except at qual once a year (back then). Sig 226 mags loaded -1 and never had any problems with them, ever. Years later I still have one of the mags and it still functions flawlessly.
