    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.

    its called spring set, the 1911 spring is heavier gauge because they only hold 7 or 8 rounds they are less likely to be effected as much but with lighter springs in high capacity mags can be effected by spring set.if you want to read more about it you can at www.gunsprings.com/faq

    C3: I read about some grave relocation and they found a corpse w 1911 locked and cocked. I suppose he wasnt too sure about his chances in the afterlife...:D Yes, it surprised everyone but it was taken to a gunsmith first to check out, after it cleared inspection, it was reloaded and all seven rounds went bang. I seem to recall it was a "ridiculous" amt of time as well. Was this what you were referring to ?
