How many rounds per life of the magazine/spring?

[Ron3]

I have some Glock springs I know are weak.

But I've replaced springs in other guns because they were very rusted or noticeably shorter than a new one.

I think the bigger issue with small magazines is rust, being crushed/damaged (clothes washer/dryer incidents happen) and just getting lost.

I'll get a few extra mags for the guns that are out of production.

A good reason I don't run any of the Chrome Silicon springs for AR buffers or mags. Magpul stuck with SS springs in the Pmag testing due to the corrosion test failures of those silly aftermarket springs.

I remember hoping on that band wagon, pushed by someone here-heavily. Yeah, rusty springs, replaced by vendor and dumped mags during the "scare"

Yeah IMO damage / debris getting in the mags over the life of the mag is more of a limfac that spring cycles.

A quality mag spring, should never reach its L10 life. I would bet money, that a manufacturing defect, would kill one early in the life cycle, before wearing one out.

Improper installation would be another one, that may reduce the life as well.

As Doc said, buy has many as you can. I have 10, HK USPc 45 mags. I have more money in mags, than the gun is worth.

I am a firearms instructor at work. When my officers come to the range, I have them use the same 30 training mags to keep their carry mags from getting worn/damaged. Generally between 4 and 5 officers a day, 2 days a week every year. I started noticing a shitload of magazine related malfunctions on the line a couple months ago. That particular lot of training mags was approximately 5 years old. Mags were replaced and the stoppages have gone back to zero. HK pistol, BTW.

ETA - What does it prove/mean? No ****ing clue, but there it is!

I bought a bunch of used P226 .40 SW mags that were LE trade ins... after validating them against some newer mags at the range.... a few seemed weak... so I just replaced the entire batch of mag springs from Wolff...

On my carry guns..the mags I keep loaded function the same as my spare mags that are not loaded...
