1911 Sear Spring

Features

1. Three-Finger JMB Design — Faithful to John Browning's original three-leaf layout, controlling the sear, disconnector/trigger return, and grip safety from a single flat spring.
2. 1911 / 1911A1 Compatible — Drops into GI-pattern 1911 and 1911A1 frames, including Colt Series 70, Series 80, 1991, Government, and most Colt-clone variants.
3. Spring Steel Construction — Heat-treated flat spring steel holds its temper and tension through thousands of cycles without taking a set.
4. Controls Sear Engagement — Right-side leaf maintains constant pressure on the sear, keeping the hammer locked at full cock until the trigger is intentionally pressed.
5. Trigger and Disconnector Reset — Center leaf returns the trigger forward and resets the disconnector for the next shot.
6. Grip Safety Tension — Left-side leaf pushes the grip safety outward, blocking trigger travel until the pistol is properly gripped.
7. Critical Tune-Up Part — A correct, properly tensioned sear spring is essential for any 1911 trigger job, refresh, or full rebuild.
8. Gunsmith-Fit Component — Allows a qualified gunsmith to tune leaf pressure for a crisp, consistent trigger pull without sacrificing safe sear engagement.
