    Interesting, I have 3 CZs (82-2075RAMI-75B) that have been loaded damn near continously for 3 years that have yet to malfunction related to the magazines. ( The RAMI did have some feed issue but that was a known factory issue that was corrected by a fluff and buff)
    See, it's mumbo jumbo like that and skinny little lizards like you thinking they the last dragon that gives Kung Fu a bad name.

It's possible to happen from repeated compression/decompression, but I seriously doubt any normal user here needs to worry.
    And this is why some will claim it's totally a myth. One never knows who will experience it or on what firearm(s). I'm not claiming they are worn out, I'm saying they can/may fail and there's a big difference. Normal use shouldn't be an issue because normal use isn't being stored loaded to capacity for extended periods of time. Some might log thousands of rounds and never experience this, some might log just a couple hundred and experience it. Look at it this way:

    When a spring is held out of shape over a period of time that spring will eventually begin to lose its shape and will cease to function as initially intended by that particluar design. It takes on the shape of the type and placement of the tension it is placed under, an example would be taking a coiled spring and trying to hold it out in a straight line...it will eventually try to follow the tension to conform to a straight line as much as possible thus deforming the original shape and functionality of the spring. This should hold true for both positive and negative pressure, uncoiling being the negative pressure.

    If that holds true, and physics says it should, then a magazine spring under compression with uneven compression points throughout should display weak points and failures over time. If this were not true then springs would ever need replaced and we all know they do from time to time. The million-dollar question is under what circumstances and when will this occur, clearly there is no answer that can be scientifically tested. It could just wind up being a bad batch of metal that day. 1911 shooters can attest that they have had to stretch their mag springs from time to time, it's not a permanent fix but it gets the job done at that moment.

    Isn't it better to have the extra mags in the event of a failure so you can keep on shooting? Folks, this is no different than carrying just 1 magazine for your self-defense firearm. If that mag fails you're in trouble. None of us wants to experience a magazine failure at a critical juncture and Murphy's Law says that's when it is likely to happen.


    Treo, my CZ mags that failed were CZ-75 magazines that may have been NIB older CZ-75 mags. They were not the newer SP-01 or P-01 magazines. Those mags I had no problems with and carried them to capacity for well over a month before my extras came in. I also experienced a similar problem in a Tanfoglio 45 mag recently becuase I forgot to unload the mags after a pistol match like a dummy, shame on me.

    I've got an old Llama .380 baby 1911 made in the 80s... with some exceptions by the previous owners(dad & grandfather) the original mag has been loaded to capacity almost this whole time. About 1000 rounds have been fired with the original mag. The barrel is actually in worse shape than the mag... and in need of replacing in about 500 more rounds(ish).

    Just a story I thought I'd post about mag life. Take from it what you will.

    Cam said it correctly

    I will shoot about 2000 rounds of 9 mm a month, but.... once I finish at the range I will clean my magazines like I do my firearm. My same magazine are used for competitions and self defense, the only two I do keep completely loaded (18 rounds) are for home/self defense and that may change if I decide on a Mossberg 18.5" barrel 12 ga. The remaining magazines I usually will load them the day before I shoot and I will run 500 rounds once a week at the range, most competitions I will shoot about 250 rounds of ammo, 200 for the match and 50 for practice. My magazines are still is good shape, although by paying attention noticing when you are running a filled capacity magazine and about 3/4 of the way down you find the firearm is not chambering the bullet correctly it is more than likely to replace the spring.

    The main thing that is hardest on the springs is during practice and whatnot when the gun is getting hot. Cycles of hot and cold are the worst enemy of a spring. Anything else is a manufacturer's defect or user neglect or abuse.

    Instead of replacing springs in working magazines, I'd buy additional magazines. In almost 40 years of shooting firearms, I haven't seen a magazine spring failure.

  11. Stretch

    Take the spring out and stretch it out. We did this to our M4 mags and it works. My Ruger P345 that I've had for 10yrs and my mags stay loaded with no spring issues. Good luck
