Wolff Officer 1911 Hammer Spring – Mainspring 18 Pounds

Wolff Officer 1911 Hammer Spring / Mainspring – 18 Pounds

The Wolff Officer 1911 Hammer Spring / Mainspring – 18 Pounds gives your Officer‑size 1911 a lighter, cleaner, and more responsive trigger feel. Because it is noticeably lighter than the factory 23‑pound spring, it reduces hammer tension and makes the trigger break easier to control. As a result, your pistol feels smoother and more refined during each shot.

Lighter Tension for an Easier Trigger Pull

This 18‑pound spring drops five pounds below the standard Colt mainspring. Therefore, it produces a softer trigger pull and reduces the effort needed for each shot. Shooters who want a lighter break—especially for range use or competition—often choose this spring for improved comfort and control.

Reliable and Consistent Hammer Function

The mainspring controls the hammer’s force and plays a key role in how your 1911 cycles. Over time, worn springs can create inconsistent hammer strikes and uneven trigger feel. By installing this 18‑pound Wolff spring, you restore smooth, predictable hammer tension. Consequently, your pistol cycles more consistently and feels more responsive.

Ideal for Trigger Tuning

Wolff offers mainsprings in several weights so shooters can tune their 1911 exactly the way they like:

• Lighter springs reduce trigger pull

• Heavier springs increase hammer force

This 18‑pound version appeals to shooters who want a noticeably lighter pull while still maintaining reliable ignition with most setups. It works especially well for competition‑ready builds or range pistols where a softer break is preferred.

Durable Wolff Construction

Wolff manufactures each spring from high‑quality spring steel that resists fatigue and holds its shape. Because of this, the spring delivers long service life and consistent hammer tension, even after thousands of cycles.

Installation Notes

Installing a mainspring requires disassembling and reassembling the mainspring housing. Many shooters can complete this task with basic tools, although professional gunsmithing is always an option if you prefer.
