Thunder Mountain Custom 1911 Sear Spring – Light – 3 Pack

The Thunder Mountain Custom Reduced Power 1911 Sear Spring – Light gives your 1911 a cleaner and lighter trigger feel. It reduces trigger pull by about 1.5 pounds while still keeping safe and reliable spring tension. As a result, you enjoy a smoother break, better control, and a more responsive shooting experience.

Because this spring follows the classic 3‑finger sear spring design, it supports the sear, trigger return, and grip safety just like a factory spring. However, it uses lighter tension to deliver a softer pull without sacrificing proper function. Therefore, it works well for shooters who want a cleaner trigger for competition, practice, or general accuracy improvement.

Improved Trigger Feel

This spring helps reduce trigger weight in a simple and effective way. You immediately feel a smoother pull, and your shots break more cleanly. Although the pull becomes lighter, the spring still maintains the pressure needed for safe operation. Additionally, it offers an easy way to tune your 1911 without replacing major components.

Built from Quality Steel

TMC manufactures each spring from strong, high‑quality steel. This keeps the spring consistent over time and ensures it maintains proper tension through long-term use. Because of its durability, it is a smart upgrade for new builds and older pistols alike.

Gunsmithing Recommended

Installation requires basic gunsmithing knowledge. If the hammer follows the slide after installation, the hammer and sear engagement needs attention. This issue comes from improper engagement—not from the spring itself—so a qualified gunsmith should correct it before use.
