Main Springs 1911 / 2011

The main spring (or hammer spring) is a foundational component in your 1911 or 2011's fire control system. It drives the hammer, impacting the firing pin, and significantly influences your trigger pull. For competitors, choosing the right weight is crucial for desired trigger feel and reliable ignition in USPSA, IDPA, and IPSC matches.

The Engine of Your Fire Control System

Optimizing your main spring calibrates trigger and ignition precisely:

  • Trigger Pull: Lighter springs reduce pull weight, offering a crisper, lighter break.

  • Reliable Ignition: An adequate spring ensures consistent primer ignition, preventing costly light strikes.

  • Lock Time: Lighter springs can contribute to faster hammer fall, subtly reducing lock time for ultimate precision.

  • System Balance: The main spring works with the firing pin and spring; correct choice maintains overall ignition system reliability.

Shooters Connection offers various 1911 and 2011 main springs, allowing you to meticulously tune your pistol's performance.

Choosing the Right Main Spring Weight

Selecting the ideal main spring weight balances trigger feel and ignition reliability:

  • Lighter Springs (e.g., 15-18 lbs): Common for lighter pull. Often paired with lightweight firing pins for reliable ignition, especially with softer primers.

  • Standard / Heavier Springs (e.g., 19-23 lbs): Provide robust hammer strike, ensuring maximum reliability with a wide range of primers, including harder cups. Result in a slightly heavier pull.

  • Ammunition & Primer Type: Softer primers (like Federal) are more forgiving of lighter main springs; harder primers (like CCI) typically require more hammer energy.
