Hello, I'm new in the world of AR's  this may have already
been talked about before, but I could not find it. My question
is will it hurt to leave magazines loaded?, I have G.I. mags and
Pmags and I don't want to mess them up, so I don't know what
to do. I have had my glock for years and my AK and I have never
left them loaded for the fear of the springs getting weak. Has any
of you ever left mags loaded for long periods of time? and did it
have any effect on the spring or the lips?

Thanks, smokingguns

Load 'em up. Don't worry about them. They only wear out from continous use,not loading and forgetting.

Only about a thousand times!

Seriously... engineers will tell you that spring fatigue comes from flexing them, not from compressing them and leaving them that way.

What happens is that every time you bend a spring, microscopic cracks form in the metal and weaken the spring. If you compress the spring and leave it that way, they dont form.

I don't have any problems having my USGI, steel, PMAG, and Lancer mags loaded for a long period of time.

Most of my loaded PMAGs which I don't even install the storage/ dust cover for over a year, they still work fine, same with my other mags.

Just keep plenty of spare mag springs and when the time comes that they get worn out just replace them.
