Recoil Springs

Rated 5.00 out of 5 based on 1 customer rating

Make sure your recoil spring is correctly matched to the ammunition you are shooting. When you have the proper weight recoil spring for a particular load, ejected brass should land 8-12 feet away. If brass is falling within a few feet of you, your spring is too heavy for that load. If brass lands more than about 12 feet away, your spring is too light for that load. Either case leads to reduced reliability.

We recommend replacing the recoil spring every 3,000 rounds. Ed Brown 5″ 45 ACP 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″ 45 ACP Commander models are equipped with a 20# recoil spring (our part number 920-C).

    Best of several spring tried for my Gold Cup


    I tried this Ed Brown 9165-G 16.5# Government spring against the Colt 16# standard issue, ISMI 16#, Wolff 16.5# variable spring, and a Colt 16# with 1.5 coils clipped off. All functioned perfectly with Federal 230 ball and Winchester reduced power 185 target loads, but the Ed Brown was very smooth and suppressed recoil better than the rest. Very comfortable. Very stiff, toughly constructed spring which easily but tightly wound onto the Gold Cup spring guide. Muzzle flip was minimized, and recoil snap to the hand was also. I’m going to experiment with this and the 18# version as replacements for the dual-spring setup in the Delta Elite 10mm. Excellent product
