    How do you know when it's time to replace mag springs? Why do I see some going to a +5%, 10% or +15% spring?

    It is dependant on if you leave the mag loaded 24/7 or only load it when you are at the range. The Law Enforcement agencies that are really on the ball have their smith change out the springs every year or so, but these guns are loaded all the time.
    I've got 30 year old guns that have their original mag springs in them. The heavier springs are generally for older guns that might have a feed problem or competition (Race) guns. Get referrals to a competent gunsmith and have him advise.

    Lifespan of magazines springs depends greatly upon the quality of the metal used to make the spring. Cheap magazines are likely to come with cheap springs that will quickly lose their tension. Quality springs will last a very long time.
