Wolff Officer 1911 Hammer Spring – Mainspring 21 Pounds

Wolff Officer 1911 Hammer Spring / Mainspring – 21 Pounds

The Wolff Officer 1911 Hammer Spring / Mainspring – 21 Pounds gives your 1911 Officer‑size pistol a lighter and smoother hammer action. It reduces the tension compared to the factory 23‑pound spring, which helps create a cleaner, easier trigger pull. Because of this, your pistol feels more responsive and offers a more refined shooting experience.

Lighter Tension for a Lighter Trigger Pull

This 21‑pound spring drops two pounds below standard Colt mainspring weight. The reduced tension lets you lighten the trigger pull while still keeping reliable ignition. Shooters who want a softer, smoother break often choose this spring for improved control and comfort.

Consistent Hammer Performance

The mainspring sits inside the mainspring housing and controls the force applied to the hammer. A worn spring can cause inconsistent ignition and uneven trigger feel. Installing a Wolff 21‑pound mainspring restores steady tension and smoother cycling.

Great for Trigger Tuning

Wolff designs a full range of mainsprings to help you tune your 1911 to your style.

• Lighter springs reduce trigger pull weight

• Heavier springs increase hammer force
  The 21‑pound version offers a noticeable improvement in smoothness without going extremely light. It works well for competition, range use, and shooters who prefer a softer trigger.

Durable Wolff Quality

Wolff builds this spring from high‑quality spring steel. The material resists fatigue and holds its shape through repeated cycling. As a result, you get long‑lasting performance and dependable hammer force over time.

Installation Notes

Replacing the mainspring requires disassembling and reassembling the mainspring housing. Most shooters can handle this with basic tools, but a gunsmith can perform the install if you prefer.
