I keep mine loaded down by 1. Makes a good place to put the chambered round if you ever want to clear the weapon. Better than loading, taking the mag out, topping off, then reinserting. And, to me, it's slightly easier to load than a full mag.
I want rustlers, cut throats, murderers, bounty hunters, desperados, mugs, pugs, thugs, nitwits, halfwits, dimwits, vipers, snipers, con men, Indian agents, Mexican bandits, muggers, buggerers, bushwhackers, hornswogglers, horse thieves, bull dykes, train robbers, bank robbers, ass-kickers, s**t-kickers, Methodists, and the GTDS.

I won't disagree with you. I'm simply saying that for several years that wasn't what was being taught in the Colt AR15/M16 armorer classes for LE users.

For a while we were told that Colt was cycling out its function testing AR mags something like every 90 days (due to wear). Dunno if they're still doing it that way.

I can say that I've seen surprising service exhibited by AR 30-rd mags (as sold by Colt and a couple other companies who sell to LE/Gov buyers), even when they're being used for a few years (constantly being loaded for training/quals). Once it may reach a point where occasional (as necessary) cleaning, and maybe a follower or spring replacement, can't keep them running, though, they're ready for destruction/discard and replacement. I'd be more careful of service use mags, though.

And as for every magazine spring ever made being properly designed for the box magazine in which it's going to be used, and being tempered with exacting precision?

Well, cost savings on materials & manufacturing, meeting low bids and/or the use of third party vendor supplied parts may not always allow those lofty ideals to be realized.

That's why I've long since stopped being surprised, amazed, disappointed or annoyed when an occasional spring (or set of springs) fails to provide similar length of proper service as some other spring (or springs), even when it hasn't been subjected to numerous compression cycles, but only being left fully compressed.

People will continue to debate this subject as long as we're using wire coil springs. I doubt everyone will ever reach complete agreement.

I'll continue to remain unsurprised when 9mm mag (and recoil) spring service life may sometimes seem to exceed that of .40/.45/.357 pistols, too.

Also, He calls himself "the father of the Hk 416." Other sparse and vague phrases on his own website, and hkpro, I don't see any factual information that states exactly his involvment in any part of the design process. If you believe that, I urge you to believe that I'm the "father of the refrigerator." The father of the Hk 416 is Eugene Stoner. Some German mechanical engineer tweaked an old piston design and Hk decided to mill out parts instead of casting, and everyone wants to act like they reinvented the wheel? Please! I love Hks. I have one, and I've actually handled a 416 (not the MR556). While robust, it's not superior. I'd bet the German mechanical engineer at Hk has never even heard of Larry Vickers. Now back to the magazine issue:
I'm too lazy to find it to quote, but someone replied that the USGI 30 round magazines are actually designed to hold 28. THAT'S THE BIGGEST LOAD OF CRAP I'VE READ YET!! You show me where, in ANY firearms manual, the manufacturer suggests this, and I will gladly apologize for calling you an idiot. I certainly never came across that sentence in any firearms manual I've ever seen.
I give up. Everyone believe whatever you want. If you want the truth, demand it be backed by experiment and factual data.

You'd think if Vickers was the fraud that you claim he is that he would have been exposed by now. Still waiting on your credentials since you've called his into question.

I have fully loaded my defensive magazines for years. I've never had any issues except for some older 1911 magazines. Since I shoot a ton every week, I tend to wear my mag springs out by use. Some of my mags have been fully loaded for about a year. They've been flawless since using them again.

The discussion continues! This months American Rifleman magazine (NRA) answered the asked question "is it wise to keep magazines loaded all the time?". They say no. They go on to say that "all springs weaken under tension". They say to rotate your magazines at least every couple of months. I'm sure the same goes for all firearm springs as well.
Be an optimist but expect the worst and you'll never be disappointed!

If you don't believe in God believe in Karma!

OK, since you're so smart, here's English lesson of the day. Striking out part of your last paragraph and leaving the last sentence intact, as above, makes any sense to you?
Since it's already established that leaving the mag fully loaded for years does not affect its function, what's the point of being "worried about it"? Hence, I struck out your entire last paragraph.

That concludes the lesson for the day. You 're welcome, sir/ma'am . Get yourself some sense of humor, will you?

Btw, I leave my mags fully loaded for years, too. Never had a problem.

It's too bad that there isn't a go pound salt smilie since writing what I really want to would cost me an infraction.

Diesel pickup, lift kit, 10mm, loud exhaust, big dog.... You didn't get enough attention as kid did you?

With the amount of people leaving magazines full for years on end then having NO issues when using them it's absolutely retarded for there to be any sort of question/debate. Just bored guys/gals sitting around trying to find something to talk about or in the case of magazines, writters and publishers sitting around trying to keep advertisers happy.

For my Glock 19 I have 2 15 round mags loaded with 13 rounds.
For my M4 I have 2 PMags 30 rounders with 28.

Have not switched out mags. So looks like I am middle of road.

Load your magazines. Leave them. Don't worry about it.

Cycling them (use) is what most wears the springs.

This assumes your magazines aren't POS's, I guess.
The only thing necessary for evil to triumph is for good men to do nothing.

I HIGHLY recommend Google Chrome and Adblock to all world wide web users. (I would have left GT a long time ago without these extensions!)
