Default Magazine Spring Integrity

How long can you leave magazines fully loaded before working about spring integrity?

Indefinitely, its the constant compression and decompression that will wear the springs, not being loaded and fully compressed. I keep all my mags loaded all time, for years no problems.

He is correct. It's the action that weakens the spring.

those that argue that springs wear out while they are compressed are arguing against the laws of physics. kinda like claiming objects in a vaccum fall at different rates because they are painted a certain color.

works like this:

laydown on your side stretch your leg out straight. leave it there see how tired you get after an hour. then pull your leg in and leave it bent for an hour see how tired your leg is. then straighten and bend your leg continously for an hour. which activity makes your leg the most tired??

springs work in a similar fashion. they only wear out doing repeated work or are bent beyound their designed limits. kinda like bending your leg past its comfortable range

For some RIFLES with tubular magazines (not all, I SAID some) leaving them loaded for a LONG time can cause the bullets to start to push back into the cartridge case. Does not hurt the spring.

Documenteted case of a 1911 that had been left with a loaded magazine for an insane period of time- well over 50 years. Testers thumbed off the safety, and fired 7 rounds without a glitch.

I have always heard that the problem with leaving a magazine (rifle or pistol) loaded for extended periods was damage to the feed lips. The constant pressure could deform them. This would seem to be more of an issue with aluminum mags. The dust covers on p-mags supposedly prevent this by putting downward pressure on the loaded rounds. I don't know how much of an issue this is though, I have a couple of Glock mags that have been loaded (when not at the range being shot) for close to 20 years and still function flawlessly.
