Per Ed Brown's FAQ:

How often should the recoil spring be replaced? What recoil spring is used in the Ed Brown 1911’s?

We recommend replacing the recoil spring every 3,000 rounds. Ed Brown 5″ Government models are equipped with an 16.5# recoil spring as standard (our part number 9165-G), while the 18# recoil spring (our part number 918-G) is generally preferred for heavier loads. Ed Brown 4.25″ Commander models are equipped with a 20# recoil spring (our part number 920-C).
