The classic “old style” trigger bar spring (characterized by its smooth, arched design without a center coil loop) is specifically engineered for vintage German and West German (W. Germany) SIG SAUER production pistols from the 1980s and early 1990s. This original arched configuration is a critical component for historical restorations: the authentic factory West German plastic grips are designed with tightly recessed channels that only clear this specific spring profile. Attempting to fit a modern coiled spring under original vintage grips will pinch the spring, causing trigger reset failures or unhooking during live fire.
- Authentic Legacy Geometry: Exact blueprint match for early-generation P-series handguns to preserve collector functionality.
- Vintage Grip Compatible: The only safe solution to retain original West German checkered plastic grip panels without structural modification.
- Premium Spring Steel: Delivers proper, factory-spec vertical lift on the trigger bar for clean, consistent resets.
Compatibility:
- Fits Early Legacy German Models (DA/SA): SIG SAUER P226, P228, and P229.
- Notice: Does NOT fit modern E2 one-piece ergonomic grips or newer factory replacement grip panels engineered for the updated loop/coil style spring.
