Magazine spring compression
If I want to leave a handgun with a chambered round and full magazine in my drawer safe overnight, how long can I leave the magazine full without permanent compression of the magazine spring?
Threads here: (first few posts about magazine springs then goes off into revolvers.)

How bad is it to leave a magazine/clip loaded??

Thank you. Very informative.
Let's translate this topic over to automatic transmission springs, which is something I have plenty of experiance with. And, a spring is a spring. This is a picture of the second gear accumulator spring and housing in a 4L60 transmission.
The bigger round part with the hole in the middle is the accumulator piston which, when the trans shifts to second, is moved by oil pressure to compress the spring shown. This is how they control shift feel. It cushions the application of the clutch or band that applies for second gear. A band in this case. So imagine how many times your vehicle shifts to second gear in a day, and then multiply that by the years old it is, and you can imagine that spring compressing and releasing a jillion times. Not unlike the spring in your pistols magazine, but you don't shoot your pistol that much. If the spring is never activated and released, it does not get fatigued.
Here is one from a typical rebuild that has failed from that affore mentioned jillion compressions and releases.
I have never seen one that is broken that hasn't been subject this wear and tear. In conclusion since the spring in your pistol is made the same way, unless some outside force acts on it, it will not wear out, unless maybe you fire thousands and thousands of round through it, doing the spring on and off cycle a jillion times. Let me add that I once built a trans that had no 2nd gear from the factory. That was found to be caused by a passage that had not been drilled out. That spring was like new and the tranny had 90k on it.
