Basicly it comes down to design, if the spring is being worked right up to its elastic limit it will sag,bet your familys life on it, if it is being worked well under its elastic limit it should last indefinitely.

Is your particular magazine spring or firing spring being worked to its elastic limit? I have no idea but on a modern firearm I doubt it.

Exactly. I know that most semi 22's will not cycle subsonic ammo out of the box but after a fair but of use or being stored with the bolt open they will. This logically indicates to me that they are being worked above their elastic limit and that the least compression over time they are subjected to the least quickly they will get to a point where they need replacement springs.
