I have a thought. I'd just like to hear some other folks' opinions.
I replaced the firing pin spring and the recoil spring on my Sistema, a few years ago (just noticed my notes on this, which is why I'm bringing it up now). The old firing pin spring was an inch shorter than the new one, but that's just from the initial set, I believe.
The old recoil spring was three inches shorter than the new one and also SIX COILS SHORTER.
Because people don't understand springs at all. They think springs are "alive", need to "rest", "get weaker", "get stronger", "wear out", are "too strong", etc.
Them sprangs is jist magic!
Lets look at one thing at a time.
First the firing pin spring.
You say the old one is 1 inch shorter. If both are under pressure at rest check to see if they are the same diameter wire you might find the new one is thicker. That would mean they take the same amount of pressure to collapses and let the pin do it's job and return it with the same pressure to the rest position.
If they are the same diameter then maybe the old one got stretched at one time. But that is a guess.
As for the recoil spring.
What I said before can be true for this. But if the old one was cut that is what I have seen when someone has a ejection and reloading problem and this can fix that.(This should not be done but it works). It is usually some other thing going on.
Or it could be that the person who packed up the springs gave you the right manufacture but wrong model.

My theory is that someone was shooting squibs in it. Light target ammo, and the ammo did not have enough UMPH to eject against the full-power spring. So they cut a coil from the spring, and when it still did not eject, cut another coil, etc. etc.
Clipping coils was common for bullseye shooters in the 50's, 60's and even into the 70's.
Now, they call Brownells and order the Wolf springs of their choice.

I was wanting to shoot some low powered loads so a couple clips off a spare spring and it worked for me.
