Description
The genuine SIG SAUER OEM factory sear spring is a critical safety and fire-control component engineered to apply consistent, precise tension to the sear. This spring ensures the sear remains firmly engaged with the hammer hooks until the trigger is intentionally pulled. A fatigued, bent, or broken sear spring poses a severe hazard, potentially causing unintended discharges (drop-safety failure), dangerous automated cycling (doubling/burst fire), or an unpredictably light trigger. Wound from premium-grade, heat-treated spring steel to guarantee absolute duty-grade reliability.

- Essential Tuning & Maintenance Part: A highly recommended component to refresh during routine frame detailed stripping or a high-round-count trigger tune-up.
