Evolution Gun Works O/S Firing Pin Stop Ser 70 .45 For Rear Sight Cut Blue

Upgrade the reliability and performance of your Series 70 1911 .45 ACP with the Evolution Gun Works Oversized Firing Pin Stop designed specifically for rear sight cuts. This precision-engineered component addresses common issues like extractor rotation and slide lateral movement, delivering smoother operation and more consistent ejection in demanding tactical and range scenarios. Key Features Oversized Design: Wider than standard GI specifications (typically .466 inches) to securely lock the extractor in place, preventing unwanted turning for enhanced ejection reliability. Enhanced Thickness: Eliminates lateral movement of the firing pin stop, promoting stable slide cycling and improved lock time consistency. Rear Sight Cut Compatibility: Pre-cut across the top to accommodate adjustable or fixed rear sights without interference, ideal for customized 1911 builds. Durable Construction: Crafted from carbon steel with a blue finish and hardened to 48 Rc for exceptional wear resistance and longevity. Radius Engineering: Radiused inside corners reduce cracking risk, while the .015-inch back corner radius maintains a square edge to help slow slide opening speed.
