Mag spring integrity loaded vs. unloaded
 
I'm new in the semi auto handgun of defense use . What is the thought of leaving a mag loaded for a long period of time vs loading it just prior for use to carry ? While the spring is under compression for a long period of time, would the spring lose any of its integrity. Thanks for your input.

nope. its not the compression that hurts the springs its the actual use of the spring or the compression decompression cycle itself. the spring doesnt care if it sits compressed or decrompressed. doesnt hurt it either way. constantly unloading and loading magazines to "let them rest" does more harm than keeping them loaded.

JonM - Thanks very much for your reply. Now its time to keep all mags in a "go position" at all times

There are as many opinions about this as there are eyebrows.

This is copied from the Wolf Gunsprings website:

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


Magazine springs in semi-auto pistols are one of the most critical springs and are the subject of much debate and concern. Magazines which are kept fully loaded for long periods of time, such as in law enforcement and personal/home defense applications, will generally be subject to more fatigue than the weekend shooter's magazine springs in which the magazines are loaded up only when shooting.

Magazine design and capacity also affect the longevity of the spring. In many older pistol designs, maximum capacity was not the always the goal such as with the 7 round 1911 Colt magazines will last for years fully loaded. There was room for more spring material in these guns which reduces overall stress and increases the usable life of the spring.

More recently higher capacity magazine have become popular. These are designed to hold more rounds with less spring material often in the same space. This puts more stress on the spring and will cause it to 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 it is not always practical.

In applications where the magazine must be kept loaded at all times, a high quality magazine spring such as Wolff extra power magazine springs, will provide maximum life. Regular replacement of magazine springs will provide the best defense against failure from weak magazine springs. Regular shooting of the pistol is the best way to be sure the springs are still functioning reliably.

Sounds like wolf wants the springs to be used just the opposite of what the first reply was. Of course wolf is selling springs so go figure. A bit like the automobile manufacturer tells you to change oil every 7500 miles but the oil company says every 3000 miles who by the way just happens to be selling oil.

Personally never had a problem with a spring in a magazine and I think the only people who would have trouble with springs anywhere on their guns are competition shooters. And think about it they don't leave their mags loaded they are loading and unloading constantly. So to me Jons post makes more sense.

one other thing. when you clean your gun you should also clean and oil the magazines. people that have mag failures from keeping them loaded tend to neglect the magazine springs and they will rust just like any other piece of metal. spare mags for ccw are often kept in pockets, a pocket is a very harsh environment subject to sweat dust dirt humidity lint at body heat temps. that is a perfect environment for rust to form and start degrading your mags.
