I find it interesting that the recoil springs provided by Sig at purchase are two different lengths. For those who haven't changed out the 8lb spring, the 10lb spring is about a full inch longer.

Which begs a couple of questions:
- What effect does cutting the 10lb spring down to the 8lb spring length have on the performance?

- If I buy aftermarket springs, say 9lb, should I trim it to the 8lb length, 10lb lenght or split the difference?
