Apeiro 45 acp recoil spring

[beartrapped]

I purchased an Apeiro in .45 acp. I wanted to go with a Dawson tool less guide rod. The question I have is what strength of recoil spring should I use with the Apeiro? I will be shooting factory 230 ball ammo to start with and because of the island barrel there is a mass difference. Just looking for some input.

13-16lbs

Depends on how the sight tracker - tracks LOL

for you which spring will be best

I find Wolff Variables keep the gun running the flatest

Thank you, much appreciated. I figured I would start with a Wolf 15 lb and see where it leads me.

I ran a 14 in my 45 STI.
