Wolff Officer 1911 Hammer Spring / Mainspring – 19 Pounds

The Wolff Officer 1911 Hammer Spring / Mainspring – 19 Pounds gives your Officer‑size 1911 a lighter, smoother hammer action. By reducing tension from the factory 23‑pound spring, it makes the trigger pull easier and more responsive. As a result, your pistol feels more controlled, comfortable, and precise with every shot.

Lighter Tension for a Softer Trigger Pull

Because this spring is four pounds lighter than a standard Colt mainspring, it reduces the effort required to pull the trigger. At the same time, it maintains reliable ignition. Therefore, you get a cleaner, more consistent break. Additionally, this spring improves comfort and control during long range sessions or competition shooting.

Smooth and Consistent Hammer Performance

The mainspring sits inside the mainspring housing and controls the hammer’s force. If the spring is worn or fatigued, it can cause uneven hammer strikes and inconsistent trigger feel. Installing this 19‑pound Wolff spring restores steady, predictable tension. Consequently, your 1911 cycles smoothly and reliably every time you fire.

Perfect for Trigger Tuning

Wolff offers a range of mainspring weights to help you tune your 1911 exactly to your preference:

• Lighter springs reduce trigger pull weight

• Heavier springs increase hammer strike force

Because of this, the 19‑pound spring strikes the perfect balance. It softens the trigger pull while still providing dependable hammer force. As a result, it is ideal for range use, competition, or custom tuning projects.

Durable Wolff Construction

Wolff manufactures this spring from high-grade spring steel. This material resists fatigue and holds its shape through repeated firing. Therefore, the spring provides long-lasting performance and consistent hammer tension for thousands of rounds.

Installation Notes

To install this mainspring, you must disassemble and reassemble the mainspring housing. Many shooters can perform this with basic tools. However, professional gunsmithing is recommended if you prefer.
