Wolff Government 1911 Hammer Spring / Mainspring – 21 Pounds

The Wolff Government 1911 Hammer Spring / Mainspring – 21 Pounds gives your full‑size 1911 a lighter and smoother hammer action. It reduces tension from the factory 23‑pound spring, so your trigger pull feels cleaner and more responsive. As a result, your pistol delivers steadier control and a more comfortable shooting experience.

Lighter Tension for a Softer Trigger Pull

This 21‑pound spring is two pounds lighter than the standard Colt mainspring. Because of this, it lowers the effort needed to pull the trigger while still keeping dependable ignition. Many shooters choose this spring when they want a smoother break without moving to an overly light setup.

Steady, Reliable Hammer Performance

The mainspring sits inside the mainspring housing and controls the hammer’s force during the firing cycle. When a spring wears down, it can cause weak hammer strikes and an inconsistent trigger feel. Installing this Wolff 21‑pound spring restores firm and predictable tension, which helps your 1911 cycle smoothly and fire with confidence.

Ideal for Trigger and Action Tuning

Wolff produces hammer springs in several weights, which makes fine‑tuning easy:

• Lighter springs reduce trigger pull weight

• Heavier springs increase hammer strike force

Because the 21‑pound spring sits just below factory weight, it offers a comfortable reduction in pull weight while keeping strong, reliable hammer energy. This makes it a great option for range use, custom builds, and everyday shooting.

Durable Wolff Quality

Wolff forms each spring from high‑quality spring steel. The material resists fatigue and keeps its shape through repeated firing cycles. This means you get long service life, steady tension, and consistent performance over time.

Installation Notes

Installing a mainspring requires disassembling the mainspring housing. Many shooters can complete the process with basic tools. However, professional gunsmithing is always an option if you prefer a hands‑off approach.
