The discussion continues! This months American Rifleman magazine (NRA) answered the asked question "is it wise to keep magazines loaded all the time?". They say no. They go on to say that "all springs weaken under tension". They say to rotate your magazines at least every couple of months. I'm sure the same goes for all firearm springs as well.
Be an optimist but expect the worst and you'll never be disappointed!
If you don't believe in God believe in Karma!
