Hi all. Fisrt time here.. A question for a newbie.. Is it better to leave the ammo in a magazine for an extended period of time or should I remove the ammo? Im talking for a month or two at a time.. I have heard both sides and was wondering if i did leave it in will it weaken the spring in a mag so i may get an improper feed when I need the next bullet to chamber? Thanks!

Welcome to TFL!

Probably the most reasonable thing to do is to buy as many extra mags as you usually use and carry, and rotate them every 2-3 months. That way you got peace of mind about it. They say that the springs are better nowadays and you dont really got to rest them anymore, but it sure cant hurt.
 
Jeff Cooper has recounted a story of a man who left his 1911 cocked and locked with a full magazine in it for some God-awful amount of time, like since the end of WWII, and when the gun was finally fired, everything worked normally.

Of course, the Colonel may be a little biased, but the point is that good magazines will function a long long time even if fully loaded.

However, I ask, why take the chance? I rotate magazines every few months just to be safe.

Thats one of the reasons my bedside gun is a revolver.
 
Welcome to the posting side of TFL.

I rotate my magazines may be twice a year, if I think of it. I try to shoot up the ammo in them and load up different mags with fresh ammo. It gets done in June but I sometimes forget in September. They all have worked just peachy keen so far. I don't worry about them.
 
I leave my magazines loaded all the time. However, sometimes I start to wonder if they'll work should I need them so I take them out to the range and test them every two or three weeks. So far they have all worked just as they're designed. I let you know if that changes.;) :D
 
It doesn't hurt a thing. In the military we leave ours loaded 24/7. They have been that way for years--fully loaded. These are our daily issue mags. (I work in Military Law Enforcement). Every now and then we will take some out to test, and they work just fine. I have been taught that what wears them out the fastest is constant loading and unloading. When the spring is contantly compressed and depressed it puts a great deal of wear and tear on it. This is why we seem to go through range mags for the M-9 and M-16 like crazy. Dropping them doesn't do them any good either, but we need to train as we fight. In a real world situation we are not going to put an empty mag in our pocket when doing a reload!

That said, the final call is yours, rotating them as others have suggested certainly isn't a bad idea. I have also heard of people downloading by a round or two.

I've recently gone through a number of recently-received heirloom pistols. Several brands and sizes. Many, many loaded magazines, some still full of WW II loadings.

They all felt normal in the unloading for cleaning and oiling; I've just never worried about magazine springs, and this episode sorta bears that out.

thanks guys for the answers/ My bedside gun is a revolver but my carry guns are automatics so I am constantly unloading and loading the mags for em. Maybe Ill just do what most of you do and leave a mag loaded for a few months and then rotate it..

The problem with the answers given is that they compare apples and oranges. The original (7rd) 1911 magazine had a very large space for spring stack. Therefore, the original springs would last, even in fully loaded mags, for a long time. The newer 8 rd. 1911 mag springs, and mag springs for hi cap mags have much less space for the spring stack, which decreases the power of the spring over time. Here is the word from the best in the business, the Wolff Spring Co. http://www.gunsprings.com/1ndex.html

4. How often should I change my springs?

Wolff Gunsprings are made with the highest grade materials and workmanship. Most Wolff [recoil] springs will remain stable for many thousands of rounds. The performance of your gun is the best indicator of when a spring needs to be replaced. Factors such as increasing ejection distance, improper ejection and/or breaching, lighter hammer indents on primers, misfires, poor cartridge feeding from magazines, frequent jams, stove pipes and other malfunctions are all possible indications of fatigued springs or improper springs. Springs that are subject to higher stress applications such as magazine springs, striker springs and recoil springs will require more frequent replacement than other less stressed springs. Most Wolff recoil springs should be capable of 3000-5000 rounds minimum before changing is required. Some recoil springs in compact pistols, especially where dual springs are replaced by a single spring may require changing after 750 - 1500 rounds. Changes in your firearm's performance are one of the best indicators that a change is needed.




5. Should I unload my magazines, rotate magazines, load with fewer than the maximum rounds? How often should I change magazine springs?

Magazine springs in semi-auto pistols are one of the most critical springs and the subject of much debate and concern. Magazines which are kept fully loaded for long periods of time, such as law enforcement applications, will generally be subject to more fatigue than the weekend shooter's magazine springs which are loaded up only when shooting. Magazine design and capacity also affect the longevity of the spring. Older designs where maximum capacity was not the goal such as the 7 round 1911 Colt magazines will last for years fully loaded. There was a lot of room for a lot of spring which reduced the overall stress on the spring. In recent hi-capacity magazines, the magazines were designed to hold more rounds with less spring material. This puts more stress on the spring and will cause fatigue at a faster rate. Unloading these magazines a round or two will help the life of the spring. Rotating fully loaded magazines will also help the problem somewhat but is not always practical. In applications where the magazine must be kept loaded, a high quality magazine spring such as Wolff extra power magazine springs, will provide maximum life. Regular shooting will verify reliability and regular replacement of magazine springs will provide the best defense against failure from weak magazine springs.




6. My spring got shorter after I used it for a short time. Is it bad?

Most new springs will take a set when they are first compressed. That means they will shorten up. This is a normal event and you should not be immediately alarmed. The greater the stress on the spring, generally the more set that will occur. All Wolff springs take this set into consideration. The ratings of the springs you receive are the ratings after the set has occurred. After set has taken place, the spring should remain essentially stable.

Since the mag springs are only $7 or so, I consider them cheap insurance, and change them every couple of years. Walt
