is it ok to leave them loaded for long periods of time ?

Periodically cycle them because the spring will get compressed and not catch the slide when the mag is empty during shooting.  Every 3 to 6 months cycle them out.

This is incorrect.

Cycling is what damages springs. Not, constant compression.

Leave 'em loaded. Won't hurt them a bit.

I have had problems with Glock magazines when I keep them compressed for long term and the mag will not catch the slide after emptying a clip.  Then if I disassemble clean and get the spring to uncompress no problems.  My M-16 clips have this issue and we take the mags apart often and make sure the spring is not getting compressed so we do not have a jam in our rifles because the spring is not feeding properly.

How would cycling damage the spring when they are cycled in weapons repeatedly the metal of the spring being compressed say in the heat of a car would do more damage then cycling for which it is designed.

Springs must be different in clips versus magazines.

I'm only familiar with magazine springs.

This is interesting i wonder if the springs act differently between different weapons pistols and rifles.  I wonder if their has been a study on magazines other then the M14 mag like the previous guy posted.

All I know is it fixed my issue in my G37 when it was not catching the slide anymore (the follower was normal also did not need to be changed).  I hope some more people weigh in on this I would like to know everyones experiences.
