N/A Decocking pcp!!!

I'm curious. Why would you store it cocked? To answer your question, yes, a coil spring will suffer fatigue if compressed for a long period of time. How important is it? Think about the valve springs in your car engine. They are under various states of compression all the time. When did you replace one? I would be more concerned about safety. There are several pieces that are more likely to fail than the spring, which could result in a discharge.
 
Any spring left in compression will lose an amount of force, so I always decock any of my guns.
That's debatable, but even the speculation of which makes me want to not leave them cocked.... I think what primarily causes fatigue is repeated compression and expansion. It is likely in some scenarios that storing compressed would cause some minute amount of fatigue. Any of which is undesirable for a consistently performing rifle. In something like a firing pin or hammer spring used to fire a primer on a cartridge this would matter little. Or something like a magazine spring. But something directly impinging on the power production mechanisms if not an integral part of this.... I would avoid.

But there are more importaint reasons to not do this, like the gun being cocked!! I store my handgun cocked, but I dont store hunting rifles or shotguns cocked. Or anything else for that matter. Just the one sidearm.
 
Safety demands NEVER leaving ANY gun cocked! Just asking for trouble.
Agree but there is always a “ ready “ gun.

In regard to hammer spring I once kept my HP Carbine cocked for 4 months …
Testing it afterward was shocking as there was no fps loss …. I already had another hammer spring ready to go for it.
 
leaving a spring compressed will not weaken the spring.
As Long_Gun_Dallas said, repeated cycling of the spring is what will eventually wear it out, but even that will take a very long time.
It depends on the quality of the spring material. I know the spring in my liberty weakened and I didn't leave it cocked either.
 
There's absolutely no reason to store a PCP cocked and loaded when you can cock it in a second.

If your "ready" gun is a PCP, that in itself if a real problem.

Even during the great rat wars I have been plagued with, I have been able to even load a 1377, pump it, and get a kill shot off.
There's absolutely no reason to store airguns cocked outside of pure laziness and complacency of their user.
Even unloaded, a blast of pressure coming out the barrel to someone who for that split second forgets it's cocked should be reason enough.

…. or I could just be use to condition one, cocked and locked.

To be clear it’s a opportunist pester not self defense.
 
it wont hurt the spring , i keep one cocked 24/7 lol .. yeah it can make a difference both in time into action and noise if youre needing to be stealthy .. theres also magazine issues with some guns depending, you may have to rod a pellet out every time which is a pita if its daily, or youre in a situation where theres one in the pipe but you cant chuck a mag in till you fire it and recock it, again .. it can be a logistical disadvantage depending on the scenario .. sure, keep it cocked on the wall, long as you know nobody is around to get into it and blow your bedroom window out lol ..
