Will leaving your magazines fully loaded ruin them in the long run? Fact or fiction? Has anyone ruined there mags by leaving them loaded for a long period of time? My XD .40 sub compact is my everyday in my bag pistol I always keep two mags loaded at all time that's why I was wondering this..

Compressing and expanding the springs is what wears them out. Ever had a Pogo stick as a kid? They're fine when no one uses them. But they lose their bounce eventually when you ride it often.

I'm not a metallurgist, so I can't relate all the techie speak, but leaving a spring compressed or expanded is perfectly fine.

And for perspective, a friend of mine in the Marines Managed to hang onto the same M16 mag his entire enlistment. 4 years, extensive training, and three tours overseas, and it worked fine.

Now, some here have managed to wear out mag springs. Hell if I know how. They obviously have way more ammo money than I do.

Agreed. Most objects wear out more from movement, not constant pressure.

I have personally seen it cause issues with 92f mags. We were taught to rotate our mags periodically.
The problems were more likely one or some of being dirty, rusty, out of spec, constantly being loaded and unloaded as often happens when used in military security roles.

Leaving a spring compressed inside its designed parameters will not hurt it. Its scientific fact. Its the movement itself of compression and decrompression that damages springs.

You do far worse damage to a magazine by unloading them to "let them rest" and none at all just leaving them loaded.

That being said, unless you shoot a damn lot of rounds, like in competition, or sit in front of the tv just loading and unloading a magazine your never going to wear one out.

Its a non-issue. Keep them clean, wipe down the springs and internal parts when you clean your gun and they will last several lifetimes

Dirty may have been the case, however, we were directed by our team squad leader to rotate mags so that's what happened. They were cleaned at that time too.

The mags for my XD45 stay loaded, but i do load one short as a hedge. I would hate to need to buy 10 or 12 springs to rebuild those mags.

It very well maybe the sand from the environment we were in but I seem it multiple times. If loading and unloading the wears them out I will just take my chances.

There were a couple of 1911 mags that had been loaded and unused for almost 50 years. The 1911, the mags and the ammo all functioned perfectly.

I have 1911 magazines that have been loaded for 35+ years and function just fine.
