Don't save money on your mags pedes. A cheap or old spring could mean your death if it is too slow.

Don't store them loaded long term or the elasticity will wear down over time. There is a myth surrounding this that it won't because of one property that is commonly quoted, the elastic limit. What causes your springs to wear down is accelerated corrosion caused by the tension, and also deformation from creep.

Finally, never shoot limp-wristed. The loading mechanism depends on you to hold the weapon firm while it blows back. If the whole weapon blows back with the upper receiver, the receiver will not spring forward with enough momentum to properly load and will jam every time.
