Wolff Officer 1911 Hammer Spring / Mainspring – 20 Pounds

The Wolff Officer 1911 Hammer Spring / Mainspring – 20 Pounds improves the hammer tension in your Officer‑size 1911, giving you a smoother and more responsive trigger pull. By reducing the factory 23‑pound spring to 20 pounds, this mainspring delivers a lighter break. As a result, your pistol feels more controlled and provides a cleaner shooting experience every time.

Light Tension for a Softer Trigger Pull

This 20‑pound spring is three pounds lighter than standard Colt mainsprings. Therefore, it reduces trigger pull force while maintaining reliable ignition. Shooters who prefer a softer, more responsive break often choose this spring. In addition, it improves comfort and control during extended shooting sessions.

Consistent Hammer Performance

The mainspring sits inside the mainspring housing and controls hammer tension. Over time, a worn or fatigued spring can cause uneven hammer strikes and inconsistent trigger feel. By installing this Wolff spring, you restore steady and predictable hammer force. Consequently, your 1911 cycles smoothly and consistently.

Perfect for Trigger Tuning

Wolff offers a variety of mainspring weights, which allows shooters to fine‑tune their pistols:

• Lighter springs reduce trigger pull weight

• Heavier springs increase hammer strike force

The 20‑pound spring strikes a balance. It provides a lighter, more refined pull while still maintaining dependable function. Therefore, it works well for competition, range use, or everyday carry.

Durable Wolff Quality

Wolff builds this spring from high‑grade spring steel. This material resists fatigue and retains its shape through repeated firing cycles. As a result, the spring provides long-lasting performance. In addition, Wolff’s precision manufacturing ensures reliable hammer tension shot after shot.

Installation Notes

Installing the mainspring requires disassembling and reassembling the mainspring housing. Many shooters can perform this with basic tools. However, if you prefer, a professional gunsmith can complete the installation.
