    There is nothing wrong with keeping them loaded.

    All loaded.

    Springs wear out by cycles, not compression.

    This is correct. All of my 30rd Pmags are always full.

    I would not fully load mags.

    30 rd mag = 27 rds. This keeps all the tension off the springs.

    JMHO

    But you also have to think that they are making better springs now-a-days, so fully loading may not harm.

    GI mags yes, but PMAGs are good to go with a full 30 rounds.

    ARC mags are also good to go with a full 30 rounds.
    Perhaps your sole purpose in life is to serve as a warning to others.

    I've got lots and lots of AR mags. I keep the majority loaded. All are downloaded by a couple rounds, but I probably don't need to do so. Same with lots and lots of Uzi and AK magazines.

    I have no idea about the 27 VS 30 round thing, but it's a fact of physics that a spring with 27 rounds pushing on it is not wearing any less than a spring with 30. As has been pointed out, springs don't wear when they are compressed or when they are released, they only wear when they are cycled between the two states..

    Downloading aluminum AR mags is not about reducing compression on the springs. There are problems with the mags seating properly with a full 30-round load on a closed bolt, but the problems are alleviated when you download to 28 rounds.

    The only real problem with leaving magazines loaded for long periods of time is feed lip spread. Again, this is more noted in GI mags than in ARC mags, Pmags, and Lancers.
