TMC Light Pull 1911 Sear Spring – 100 Pack

Thunder Mountain Custom Light Pull 1911 Sear Spring – 100 Pack

The Thunder Mountain Custom Light Pull 1911 Sear Spring helps you achieve a lighter, smoother trigger pull while keeping safe and reliable spring pressure. It is a proven upgrade for gunsmiths and serious 1911 builders who want consistent results across multiple pistols.

First, this sear spring reduces trigger pull weight by approximately 1.5 pounds. That reduction improves trigger control, shortens split times, and enhances overall shooting confidence. At the same time, the spring maintains proper tension to support safe operation when installed in a correctly set up fire‑control system.

Next, Thunder Mountain Custom manufactures these springs from quality steel to ensure consistent performance and long service life. The spring flexes smoothly and returns reliably, which helps maintain a predictable trigger feel over time. Because of this consistency, it works well for competition pistols, duty guns, and refined range builds.

In addition, this listing includes 100 sear springs, making it ideal for professional gunsmiths, armorers, and high‑volume builders. Having a large quantity on hand allows you to tune multiple pistols without delays or mismatched components.

However, proper ignition geometry remains critical. If the hammer follows the slide after installation, the hammer and sear engagement is incorrect and must be corrected before use. For best results, a qualified gunsmith should install and tune this spring as part of a complete trigger job.

Overall, the Thunder Mountain Custom Light Pull 1911 Sear Spring offers a reliable way to reduce trigger pull while maintaining safety, consistency, and professional‑grade performance.
