Drop‑In Firing Pin Stop – Series 70 – .45 ACP – Blue

Restore proper function and reliability to your Series 70 1911 with this EGW Drop‑In Firing Pin Stop for .45 ACP pistols. Designed as a direct replacement for factory parts, this firing pin stop installs easily while offering improved durability and controlled slide movement.

EGW machines this firing pin stop from carbon steel and heat treats it to a consistent 48 Rc. As a result, it resists peening and deformation far better than soft factory stops. Because the part drops in without fitting, it provides a quick and effective upgrade for worn or damaged firing pin stops.

To extend service life, EGW radiuses the internal corners to prevent cracking under recoil. In addition, the rear edge features a precise .015-inch radius. This detail breaks the sharp corner while maintaining a square profile, which helps slow initial slide opening and promotes smoother cycling.

Although this is a standard‑size firing pin stop, it still benefits from EGW’s attention to geometry and heat treatment. Consequently, it delivers reliable performance for range guns, carry pistols, and general rebuilds without the need for gunsmith fitting.

Series compatibility remains straightforward. Series 80 firing pin stops will work in Series 70 pistols. However, Series 70 firing pin stops only work in Series 70 guns.
