EGW Oversize Firing Pin Stop – Series 70 – .45 ACP – Blued

Improve extractor control and slide timing in your Series 70 1911 with the EGW Oversize Firing Pin Stop for .45 ACP pistols. This precision‑machined upgrade solves common reliability issues that standard firing pin stops often allow.

EGW machines this firing pin stop wider than factory parts to stop extractor clocking. As a result, the extractor stays properly aligned during cycling, which leads to more consistent ejection and improved reliability. In addition, EGW makes the stop thicker than standard to remove lateral movement, giving the slide better control under recoil.

To enhance durability, EGW radiuses the internal corners to prevent cracking during extended use. At the rear, a precise .015‑inch radius breaks the sharp edge without rounding it excessively. This design keeps a square profile where it matters most, helping slow initial slide opening and reduce slide battering while maintaining smooth operation.

EGW heat treats each firing pin stop to 48 Rc and Rockwell tests it for consistency. Because this part is intentionally oversized, it is not a drop‑in component. Proper fitting is required. However, that fitting process delivers the tight, precise fit that produces the real performance benefits shooters and builders expect from an oversized firing pin stop.

This firing pin stop is designed for Series 70 .45 ACP 1911 pistols. Series 80 firing pin stops will function in Series 70 guns, but Series 70 firing pin stops will only work in Series 70 pistols.
