Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
If being compressed ruined springs, car springs wouldn't last 25 years at a time.
I guess I just haven't had any of my guns long enough to ruin them by leaving the mags loaded. Mine have been loaded for going on three years now, and have yet to have a failure related to mags.

For me...
Carry ammo is always tested... usually 2-5 mags to ensure it cycles. I keep two mags fully loaded, 1 in the gun, 1 extra mag that i carry. 24/7... in the past i've always shot the two mags that i keep loaded once a year, that time is coming up again, so i thought i would post the question.

My Feedback
Car springs are loaded, not fully compressed like a full mag. I guarantee you those mags loaded for 3 years are far from the same strength as a new mag spring. Test it. I did.Originally Posted by Sturtle
Mag springs for my carry guns get changed at least once a year. They are just too cheap to not.
I can't argue that mag springs are cheap.

Ever look at the suspension on 70's Chrysler products, where you'd have to put 4 inch extended shackles on 'em just to get them to sit level(in the early 80's)?
Springs will take a set, and lose tension when placed under stress. This effect is less noticeable in helically wound springs (most magazine springs), and those that are lighter in rate, but longer and with greater preload.
As foxtrot mentioned earlier, there is a difference in types of springs, with helical being better than leaf springs for durability. I have also seen very old magazines that are fine and have been sitting loaded for over 40 years (M1 carbine primarily but others as well).
From what I have read, spring metallurgy will hold up very well under constant (but not excessive) pressure, but use is still the best way to wear out a spring. As for the old cars, there are many people who park uphill and leave excessive stress on the rear springs. That along with 200k or so and/or towing will take their toll. Another possible factor may be that some cars were simply made with higher quality spring steel...
I personally leave out a few rounds from a magazine and don't worry about it. I still rotate magazines on occasion as well, but not because it is a big concern, more for peace of mind than anything else.
No. All my firearms are loaded and I do change mags ever so often. I do shoot my carry ammo when i forget to change it out with FMJ.
Thank you Foxtrot. I have read things like that many times before, but since I've never studied metallurgy; it would have been silly for me to try and argue.

I cycle mine, out the end of the barrel..
