Keeping mags loaded or not?

Post by FN574me » 22 Oct 2012, 19:52

A buddy of mine claims that keeping mags loaded at all times tires out the springs and adds to duds. He says it is best to keep mags empty. Any opinions?

By the way, I only have two 10 rounds mags (CA restriction). Should I buy a few more?

Thanks.

The mags that are stored with my weapons are loaded. The ones that are not, are not. They get shot or swapped often enough that it is not an issue.

I keep a few mags loaded but not all & not to max. For instance, if the mags holds 7 or 8, I'll leave it with 5. If it holds 20, I'll leave it with 15.
Belt fed is another story.

:agree:

actually back in vietnam and for a few years after that the troops were told not to load their 20rd mag up, only load to 18. the last ime I had to do that was in 79, after that we went to full load. I very seldom had a FTF or FTL :?:

There is no reason to download your mags. Springs wear from duty cycles, not being loaded to their designed tension.

Any engineer will tell you this is a non issue.

The reason many troops load AR mags at -2 is because it is said that being loaded to 30rds for a long time can cause the mag lips to bend slightly. Obviously this is not a concern with the polymer mags of the FsN.

Yep, there have been many interweb debates over this issue and the science seems to support that constant compression doesn't wear a spring out, its being sprung and unsprung over and over that wears them out. There have been reports of .45 mags being loaded and stored since WWII taken out and fired with nary a feed issue. One warning that is sometimes issued is to not over load a spring. So perhaps the theory of loading one under the max is prudent advice. That being said, my FsN carry magazine is loaded to 20 always and I have full confidence in it.

Like blueorison told me whether the spring is callapsed or loose (loaded or unloaded) it doesant matter but after use is when it will start to lose tention

I keep them loaded. An empty mag is a paper weight.

And not even a very good paper weight in the case of a FiveseveN magazine. That thing is practically weightless.

My mags serve a dual purpose as handy little storage containers that keep the cartridges lined up straight.
