Rumor of using Mossy 500/590 Wolff spring in 930

[FrankAR15]

Read you can use the 500/590 springs on SPX somewhere on Internet, lol. Wolff does not make a spring for the 930.
I am assuming the Wolff springs have finished ends?

Even though mine is not a SPX, it is the tactical with 2round ext(6+1)

Wolff offers 2 different sizes;

1)Sku 17901
For use in:
Mossberg 500 12 & 20 ga - 6 shot (5+1)
Mossberg 590A1 - 6 Shot (5+1)

--or--

2)Sku 17905

For use in:
Mossberg 590, 12 ga - 9 Shot (8+1)
Mossberg 500, 12 ga Extended Tube 8 shot (7+1)

I'm guessing number 2, Sku 17905.

I just am not confident in my Nordic spring that I had to turn in and bend the ends of the spring.

As long as the spring provides the correct amount of tension does it rely matter. I'm asing seriously as I've never noticed any real difference in springs between models aside from length and they are easy to trim.
