Evolution Gun Works O/S Firing Pin Stop Ser 70 .45 For Rear Sight Cut Blue - 10369

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.
