Does keeping a mag loaded for a very long time affect the spring ?
Yes, any spring put under prolong compression will weaken more rapidly. I'd suggest you unload your mags unless you want to buy new ones more frequently. I keep 1 mag loaded at all times for my xd, the others sit with the ammo unloaded. They springs are strong, and will last sometime even compressed but you will wear them out quicker that way. Certainly not in a weeks time but a bit sooner than an unloaded mag.
what he said
i keep one loaded in the gun, but rotate every few months, sheesh i only have three mags.
oh no here we go again
Keeping a mag loaded will not weaken the spring.
Repeated compression will weaken the spring. i.e. loading and unloading.
Why would anyone buy new mags when their springs wear out? Maybe I'm missing something in the translation... I replace the springs annually in my carry mags. I rotate them weekly. They have been tested with all of my carry ammo.
Now to the point... I have a set of three Colt .38 Super mags that my father gave to me. He kept them loaded at all times. The mags are about 20 years old and still have their original springs. Interestingly enough, they still work just fine. They feed just as good as any of the other mags I have. I can't explain this phenomenon, but it's true.
I also have mags for my Glocks that have springs that lasted less than 5,000 rounds.
My thoughts? Keep them loaded if you want, ans spend the $20 a year for a three-pack of Wolff HP mag springs.
Being constantly compressed (as long as they aren't binding) won't damage a spring. Work is what will weaken the spring and the only way to "work" a spring in a magazine is to constantly load and unload it.
You can get replacement springs for a much lower cost compared to brand new mags.
I have fired a couple of mags full of 45ACP that were loaded back in 1944. Nary a hitch, folks. Those mags laid in storage for 55 years with old-technology springs at maximum compression and still performed 100%. I have fired numerous other guns which had been left loaded for years (and sometimes decades) and have never had a malfunction due to a weakened magazine or other coil spring.
Coil springs seem to do fine as long as they aren't exposed to extreme heat or cold while under compression. I do not subscribe to the theory that springs need to be "relaxed" occasionally to maintain their strength. In my experience, metal fatigue occurs when the material is "worked" (whether by thermal cycles, pressure changes, or physical bending/ twisting/ stretching/ etc.), not when it is kept in a static state.
I certainly don't see anyone talking about swapping out their pistol's mainspring every few weeks so it can "relax"...why worry about the mag spring?
Just my opinion and worth exactly what you paid for it.
i seriously doubt that storiong a mag full will have NO affect on them. but i have one that i allways keep loaded and one that i dont keep loaded the one that is unloaded is the one i use at the range so it gets compressed quite a bit but the carry mag will only get unloaded twice a month or so but i have noticed that the carry mag is easier to load the last few rounds. so this seems like to me that it does have an affect. that being said i still continue to keep it full with no worries i dont think it will ruin a mag but to say it has no affect just doesnt seem right
