Springs Springs Springs

From what I understand, springs only wear out from repeated cycling. Many leave their magazines loaded without worry. I’m not a metallurgist nor an engineer so take it for what it’s worth.

 

Repeated cycling weakens springs, If you just have it sitting there in a safe it will be fine. Springs are cheap enough so if you feel you want to change out the recoil spring after a long period of time in the safe I say go for it.

 

Im 57 now so I would probably be dead before it happened so I will let my kids worry about those guns LOL

Seriously, I made a recoil spring tester out of some all thread a copper pipe and a digital scale . Just check the springs once in a while when you pull them out to make sure they are still in the boxes

 

If you're referring to recoil springs , I see recommendations of every 2000 rounds but have gone to around 4000 rounds before replacement . ( Using a conventional spring as opposed to a flat-wire )
This seems like a reasonable estimate , however it would depend also on what ammo you're shooting . ( factory or reloads )
Inspecting your pistol at regular intervals looking for any unusual wear is always a good idea and it will help you determine your own maintenance criteria .
