I like keeping a few magazines fully loaded.
Will a magazine get damages it kept fully loaded (16 rounds of 9mm) for long periods of time??
i rotate mine every few months but with modern materials spring failure isnt as much of an issue as it used to be
keep a revolver handy instead of magazine fed pistols but thats just me.
like greasy said, rotate them. also if I'm keeping it loaded over long periods of time.... leave some space (if it holds 16, keep 14 or 15 loaded) that way the spring isn't maxed out
Magazines can be left fully loaded for quite some time with no problems. Leaving one or two rounds out isn't for preserving the magazine spring, it's to allow you to insert the magazine with the bolt closed without having to slam it in. I've left M4 and M9 magazines fully loaded for over six months and they fired fine afterward.
Cycling a spring wears it out, keeping it compressed within it's design limits is not a problem. I keep all my mags loaded, an unloaded mag is of no use to me.
There have been many topics on this recently, it will not hurt a mag. to stay loaded at all, will not effect the spring, what effects it is loading or unloading.
It is best on ar mags to load 3-4 less than cap. if stored long-term due to fact
on those the pressure can mis-align the feed lips over time if loaded!
Many cops rotate their ammo every few months, due to fact a lot of activity can cause brass ammo cases to actually get dented or slightly imprinted in a pistol, and could hinder proper feed!
I have ak mags and chin. drums that have been and stay loaded for 20+ years!
You can also keep chin. drum mags loaded and wound with no damage,
however all other drums should never stay loaded longer than 72 hrs. per soviet
Thanks guys for the info.
most "experts" state that there is no problem with keeping modern-day magazines loaded. My experience supports that.
Time records: 9mm Browning Hi-Power--7 years, perfect function
.380 Colt Mustang--5 years, perfect function
There was no indication, on reloading these mags, that the springs had weakened.
I agree i have a p89 that has been loaded most of the time for about 8 yrs. no problems.I also have read many articles stating this from many diffrent books.
