    How long to leave rounds in a mag?

    I'm kind of worried about leaving all 3 of my mags full. I've been emptying 2 of them and rotatting the full one every week. How long could I have all 3 full? Theres been so many murders around here lately, it's insane. So I'd rather be safe than sorry and have all 45 rds ready to go.

    I swap mine out every couple of months if I don't get to the range.

    Think about this, how long did the .45 mags stay loaded during WWI & WWII & Korea & Vietnam? They proboly used some of the same surplus from WWI in WWII and same for Korea and Vietnam.

    I leave them in for how ever lomg it takes me to shoot them up

    from all I have read , don't load/unload em any more than needed. The springs wear out from compressing/expanding. I used to rotate my mags like you. Now I just leave em loaded until I fire em off. I have a few mags that have been loaded since about 96' except when firing and no problems found with em.

    Post High Quality Modern Pistol Magazines

    You can leave your pistol magazines fully loaded indefinitely with no damage to the magazine spring...since even with the magazine fully charged (with its correct number of rounds) the steel magazine spring is designed to still be compressed to less than the "critical fatigue point" of the spring steel.
    Your magazine springs do not need to "rest"
    This information is according to Wolff Gun Springs.
    Some older military mags and some factory mags have springs that are not properly hardened & tempered & they can weaken due to inferior manufacture. Make sure you buy High Quality mags or replace the mag springs with Wolff or other properly made springs.

    Sorry i should edit that to say the newer Hk's in 45 only have had this problem when i started haveing terrible problems with it not picking rounds up off the mags as in not even stipping them from mags i started looking and found out ...


    I think its what wolfe says the problem is improperly heat treated i replaced all mag springs in my mags no problems since and it was fairly new when this happened you could easyly compress the mag spring all the way and it was way short

    I'm with QK. I've learned that you either leave the magazine full or completely empty. I tend to fill them up because it does soften them up a little bit sometimes so they're not so darn tight. Then again I HATE stuffing cartridges into magazines and always will. I cheat and use a speedloader. I have to admit since switching to .40 S&W my hand fatigue from loading magazines is less; the rounds are slightly bigger and there's less of them!

    I wish they made more non 1911 pattern single stack .45s just for the big cartridges in an easier to load magazine for my sausage fingers... but back onto springs - either fully loaded or completely unloaded.

    Ditto My 10 round was loaded for 4 years, now I use the 12 round, but only keep 10 in it unless I'm going someplace high risk. Yes I know why buy a 12 and load 10 unless going someplace high risk the risk may come to you, but if 10 P+ rounds isn't enough to discourage a BG and his partiner then I'm in deep dodo, and really need the shotgun with the 7 round tube.

    I guess mine stay full for carry use - until day comes to shoot off the carry ammo and reload - I will tho then usually choose a fresh mag that has had less use for a while. Really doubt it matters.

    I do wonder sometimes re some other mags - for instance I have six or so AK mags always full - four FAL mags full, and probably six L1A1 mags left full.

    In fact most semi handguns in safe have full mags too!

    Revolver

    The precious time and effort that you save by just dropping those cartridges in revolver cylinder holes....you lose by having to scrub those holes out later on with a bronze brush after you shoot it.
