Shop mainsprings and hammer springs for 1911 and 2011 pistols for replacement, maintenance, competition tuning, and custom pistol builds. The mainspring, commonly called the hammer spring, provides the spring force used by the hammer and is an important component of the pistol's ignition system.
This category includes replacement and performance hammer springs in a variety of spring weights for different 1911 and 2011 configurations. Different spring weights are commonly used when servicing or tuning competition pistols, but spring selection should be considered alongside the hammer, firing pin system, ammunition, recoil system, and other components that can affect reliable ignition and pistol operation.
There is no single mainspring weight that is appropriate for every 1911 or 2011. Springs that are too light for a particular pistol and ammunition combination can result in unreliable primer ignition. Always verify the appropriate spring dimensions and weight for your specific pistol and thoroughly test for safe, reliable function after making changes.
