    Posted: Apr 02 2017 at 11:04pm
All of my AR 15 magazines are loaded and stockpiled in my safe. I exercise them about once a year, and there seems to be no issues with this method of storage as the springs are under constant compression. Is there any problem storing original USGI 15 and 30 round magazines in a Ioaded condition? I hope to be able to secure more 15 round magazines to stockpile the 30 Carbine ammunition I am loading. Any direction would be greatly appreciated...

This is a subject of much debate in some circles. Personally, I would not recommend storing M1 Carbine magazines loaded for extended periods.

That is absolutely true. You can find pro-n-con discussions about this all over the place. I generally don't load mine up to the top. Usually keep a couple partially loaded. I do know that is some cases, a fresh magazine can be fully loaded and allowed to "soak" for a while to weaken the spring, which results in a better functioning magazine. People will say that the springs will never weaken under compression and the only way to impart fatigue is thru the cycling of the spring, but I fall-out on the side that placing the spring under full compression forever can't be good for it.

I've seen the debate in a few places over the years. One discussion involved an engineer on my website who went into great detail about the physics involved, and that it should not hurt a magazine spring. Didn't make sense to me...

I have two magazines that seem to have spring fatigue, and I've had and seen others. I keep very few magazines loaded. I do have a few handgun magazines that have been fully loaded for many years, most notably for my HK P7M8, and they are as strong as ever, in my opinion. I also know of a Sheriff's Department in Michigan who had problems with springs weakening in their Springfield Armory XD magazines. So, maybe it has to do with heat treating, or something like that, but I err on the side of keeping them unloaded.

Thanks David. I have plenty of loaded magazines for my 1911s and ARs, I think I'll give my old M1 magazines a rest. Any recommendations on replacement magazine springs for 15 and 30 round magazines, or will get pillaried because I might be altering an original item with a new part? My USGI magazines are not pristine, I have two originals that have been Parkerized that I use on the range and a NPM 15 rounder that really could use some attention, but I'm not sure if re-bluing will devalue the magazine. I have a local smith that does wonderful work and he has offered to rework two of my USGI magazines.

I have not checked for M1 Carbine mag springs, but Wolff Springs would be the first place I would check for any replacement springs.

Replacing springs is ok to do from a collector's perspective? Just save the old ones?

I think it's fine. Others may disagree. Save the old one, and you can't go wrong.

Wolff has them. Here's a link:
