Shop mainsprings and hammer springs for 1911 and 2011 pistols for replacement, maintenance, competition tuning, and custom pistol builds. The mainspring provides the spring force used by the hammer and is an important part of the pistol's ignition and fire control system.
This category includes replacement and performance mainsprings in a variety of spring weights for different 1911 and 2011 configurations. Changing mainspring weight is commonly part of tuning competition pistols, but spring selection should be considered alongside the hammer, firing pin system, recoil spring, ammunition, and other components that can affect reliable ignition and pistol operation.
Selecting a spring solely by trying to achieve the lightest possible trigger or hammer operation can result in unreliable ignition. Always verify the appropriate spring weight and compatibility for your specific pistol and setup, and test the pistol for safe and reliable function after making changes.
