Description
The genuine SIG SAUER OEM factory mainspring (hammer spring) is a vital ignition component responsible for driving the hammer forward with the necessary velocity and force to strike the firing pin. Over time and extensive use, a fatigued mainspring can lead to light primer strikes and failures to fire. Stamped from premium-grade spring steel, this factory-original replacement delivers consistent trigger pull weights, positive primer ignition, and textbook operational reliability
- Genuine SIG SAUER Factory OEM Part: Engineered to exact specifications for perfect fitment, precise tension, and maximum safety.
- Eliminates Light Strikes: Restores factory-spec hammer energy to ensure reliable ignition even with hard-primer ammunition.
- Essential Preventive Maintenance: A highly recommended component to refresh every 3,000 to 5,000 rounds to keep your duty or carry pistol running flawlessly.
Compatibility:
- Fits Classic SIG SAUER P-Series Models (New-Style Plastic Strut System): P226, P229, P220, P227, and P228 (including DA/SA and DAK configurations).
- Notice: Does NOT fit striker-fired platforms (such as the P320 or P365 series) which do not utilize a hammer or mainspring assembly.
