1911 Sear Spring

1911 Three-Leaf Sear Spring

The sear spring is the small flat spring that keeps a 1911's trigger mechanism under control. It holds the sear against the hammer, resets the disconnector and pushes the grip safety outward. When this spring weakens or a leaf cracks, trigger feel suffers and the pistol can stop working safely. This United Defense replacement suits owners repairing a worn pistol, rebuilding a 1911 from parts, or keeping a spare in the kit.

Features

• Three-Leaf Design — A single flat spring split into three fingers, each one tensioning a different part of the fire-control group.
• Sear Leaf — The left finger presses on the sear, the part that holds the hammer cocked until you pull the trigger.
• Disconnector Leaf — The center finger pushes the disconnector back up so the pistol fires only once per trigger pull.
• Grip Safety Leaf — The right finger keeps the grip safety pushed out until your hand depresses it.
• Classic 1911 Pattern — Made to the traditional three-leaf layout used in the 1911 platform.
• Black Finish — A dark finish that matches the internals of most 1911 frames.
• United Defense Part — Sold under the United Defense name as a replacement 1911 component.

Fitting and Tuning

The sear spring sits at the rear of the frame behind the trigger mechanism, held in place by the mainspring housing. Installing one means partly disassembling the pistol, and many owners bend individual leaves slightly to set trigger pull weight and reset. If you have not worked inside a 1911 before, have a qualified gunsmith fit it and function-check the pistol afterward.
