    I'm not into automatics very much but just purchased a Glock 26 for the wife to carry. I hear pro and con about filling the spare magazines and leaving them that way for however long. I don't personally see any harm in it, the one in the gun is kept loaded all the time.

    In general I agree with David E, but I have heard anecdotally that Glock magazine springs aren't as well tempered as many others and do take a "set" and wear out.

    So, load up what you need to keep on hand. When they wear out, you will know (but you'll have 13 or so rounds before they don't pop the last one or two through). But he's right. Load 'em up and keep 'em on hand. I've heard the expression that to a combat pilot, there's nothing more useless than altitude above and runway behind. The handgun equivalent would have to be "magazines unloaded." Load 'em up!

    Really? Can anyone confirm or deny this?

    load your mags, they will be fine left loaded a long long time.

    Yes, really.

    I can with my experience with Glock ownership, and you can do the same by searching this forum and glocktalk for other people's experiences which have been reported. No worse really than, say, the weak Wolff springs that come in a Wilson 1911 magazine or that Wolff sells directly aftermarket for most guns. But still much less reliable than the carefully tempered spring-steel in traditional old-school magazines, or the cutting edge chrome-silicon springs other makers sell and install.

    This is not an "unknown" or surprising fact. It doesn't demean the Glock or the virtues of it, it's just a fact that goes along with it.

    what David E said, load 'em up
    I think it's "mostly" urban myth, springs taking sets in mags

    but then again, I do keep my spare mags empty, and I do swap 'em out every once in a while
    every few months, not obsessive compulsive about it though
    if for no other special reason, just to shoot a few rounds

    hmmm... didn't know about the Glock thing
    but, you know, I prefer my peanut butter "smooth" vs "chunky" style, go figger

    It's actually not so much a Glock thing as it is a double stack hi cap thing. The springs will lose their temper if over compressed. In a double stack mag loading it up to full capacity sometimes comes pretty close to overcompressed. A spring in this application is being asked to perform over a very wide load range (fully compressed/fully relaxed) I would recommend just downloading a double stack mag by a couple of rounds to ease the load on the spring. In a perfect world where the spring is manufactured and tempered perfectly this would not be necessary but there is no reason to push the envelope if it may kill your spring and cause a feed problem.

    Leaving magazines loaded.

    7. It appears that in the vast majority of cases magazines continue to function perfectly after being left loaded for extended periods of time. I have personally left rifle and pistol magazines loaded for up to 10 years and they worked fine when put to use. I have heard others speak of getting the same results after leaving magazines loaded even longer than 10 years.

    I remember seeing an X-ray picture of a glock magazine, and it showed the spring being ULTRA compressed.

    I think it has to do with an excessive compression of the spring as opposed to "bad tempering."

    also, hurr.

    Glock was one of the first to give up spring life in the pursuit of more capacity.

    John Browning wisely limited the High-Power magazine to 13 rounds. You can leave them loaded for a century and they will still work perfectly.

    Gaston on the other hand, went with 17 rounds and over-compressed the spring.

    It was discussed at length in several issues of the Glock published, Glock Annuals, in a long term torture test written by Chuck Taylor and followed up every year.

    Bottom line was, if you want Glock mags to last indefinitely loaded, down-load them a couple of rounds.

    I download most of my mags that I leave loaded, mostly so they will seat easier if the bolt/slide are in closed position.
    I have found the factory Glock mags to be the most reliable of pistol mags for the most part.

    i keep all my mags loaded, but never to capacity unless i'm about to go to the range. generally i'll leave 8-10 rds in a 12-13 rd magazine.

    Dang how many mags do you guys have? I have well over 100 of various types and can't see using them for ammo storage, are you talking about 12 or so?

    I love what rcmodel said - " give up spring life in pusuit of more capacity " Even more amazing is the number of consumers that went along with the idea. Ask someone who carried an M16 in Vietnam about loading mags all the way to max capacity.

    Ok, I have an empty AR mag and two empty 1911 mags in my range bag... :)

    Aside from that, all my mags (25ish?) are loaded. I don't see any reason not to store ammunition in loaded magazines.
