The Colt 1911 Recoil Spring, Commander, 9mm, Inner is a direct replacement component engineered specifically for Colt 1911 Commander pistols and compatible 9mm clones that use the Colt Dual Spring Recoil System™. Built from tempered spring steel, this inner recoil spring works together with the matching outer spring to deliver a softer recoil impulse and more consistent cycling, extending recoil spring service life compared to traditional single-spring setups.

This inner spring is ideal for shooters who put high round counts through their 1911 Commander at the range or in training and want dependable function with 9mm Luger ammunition. When installed with the required guide rod and recoil spring plug, it helps maintain smooth operation and reliability over thousands of rounds. It reflects Colt’s long-standing focus on practical performance and thoughtful engineering in the 1911 platform.
