Wilson Combat 417 Bullet Proof Sear Spring 1911 Black Steel - SKU: 417 - UPC: 874218001896
Product Description
The Wilson Combat 417 Bullet Proof Sear Spring is widely considered the benchmark for premium 1911 trigger actions. Stamped and precision-formed from high-grade stainless spring steel with a durable black oxide finish, this 3-leaf spring delivers consistent tension, exceptional fatigue resistance, and long-term reliability for duty, self-defense, and competition handguns.
Engineered to eliminate trigger feel degradation over thousands of operational cycles, the Bullet Proof 417 features pre-curved leaves designed to maintain optimum pressure against the sear, disconnector, and grip safety. Its superior spring temper prevents the relaxation common in standard carbon steel factory springs, helping maintain a light, crisp, and safe trigger pull without unintended weight shifts.
Compatible across Government, Commander, and Officer frame sizes, the Wilson Combat 417 Sear Spring serves as a direct drop-in upgrade or a perfect foundation for custom 1911 gunsmith trigger jobs.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard 1911 single-stack receivers (Government, Commander, and Officer models).
- Verify host 1911 handgun is completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Field strip the firearm and remove the grip panels, mainspring housing pin, mainspring housing, and grip safety to access the lower frame pocket.
- Insert the bottom indexing tab of the Wilson Combat 417 spring into the frame slot, ensuring the left leaf aligns with the sear, the center leaf contacts the disconnector, and the right leaf engages the grip safety.
- If fine-tuning trigger pull weight, make slight, gradual bends to the leaves—bending the center leaf slightly rearward decreases disconnector resistance; bending the left leaf forward increases sear engagement reset force.
- Reassemble frame components and perform a full safety function test (checking thumb safety, grip safety, half-cock notch, and trigger reset) prior to live-fire testing.
