My friend installed a spring kit from wolff on my Beretta 92 years ago. It greatly improved the triggerpull .

What sprigs can I replace to help trigger on my Sig220?

I would beef the recoil spring up 1 to 2 lbs, then I would put a reduced hammer spring in the weapon.  The DAO spring is an 18lb, but I suggest you go no lower than a 19lbs hammer spring, that is what I use in all of mine with no issues in reliability and it lightens the trigger up a good bit.  You need to pull the grips off to see what type of hammer spring system you have, the older long springs, or the new short spring with plastic base.
