Wolff Government 1911 Hammer Spring / Mainspring – 17 Pounds

The Wolff Government 1911 Hammer Spring / Mainspring – 17 Pounds gives your full‑size 1911 a lighter and smoother hammer action. It lowers the factory tension by six pounds, so your trigger pull feels cleaner, softer, and easier to control. Because of this, your 1911 delivers a more comfortable and predictable shooting experience.

Lighter Tension for a Softer Trigger Pull

This 19‑pound spring reduces the heavy feel of the standard 23‑pound Colt mainspring. As a result, your trigger breaks with less effort and more consistency. Many shooters choose this spring when they want a smoother pull without giving up dependable ignition.

---

Steady and Consistent Hammer Force

The mainspring sits inside the mainspring housing and creates the hammer’s tension. A worn spring can cause light strikes, uneven cycling, or an inconsistent trigger feel. A fresh Wolff 19‑pound spring fixes those issues and delivers strong, even hammer force shot after shot.

Great for Accurate Trigger Tuning

Wolff offers many mainspring weights, and the 19‑pound option sits in a sweet spot. It lowers trigger effort yet still strikes primers with confidence. Because of this, it works well for:

• Range guns

• Light tuning projects

• Competition builds

• General improvements to trigger feel

It also gives you a noticeable upgrade without pushing the pistol too far from factory reliability.

Durable Wolff Spring Steel

Wolff forms this mainspring from high‑grade spring steel. The material resists fatigue and holds its shape through thousands of compression cycles. Therefore, you get long service life, stable tension, and reliable function even with frequent shooting.

Installation Notes

You must remove and reinstall the mainspring housing to install this spring. Many shooters handle this with basic tools. However, a gunsmith can also complete the work if you want a worry‑free setup.
