Oversized Firing Pin Stop – Series 80 – 9mm / .38 Super / .40 S&W / 10mm – Stainless Steel (Cut for Adjustable Sight)

Improve extraction reliability and slide control in your 1911 with the EGW Oversized Firing Pin Stop for Series 80 pistols. EGW machines this heavy‑duty part from stainless steel and intentionally leaves it oversized, giving builders and gunsmiths the ability to achieve a precise, performance‑driven fit.

First, the wider-than-standard design prevents extractor rotation. Because the extractor stays properly aligned, ejection becomes more consistent and dependable. Next, the increased thickness eliminates lateral movement, which further stabilizes the extractor during cycling.

In addition, EGW radiuses the internal corners to reduce stress and prevent cracking. This design choice increases service life, even in hard‑use pistols. At the rear, a .015″ radius breaks the sharp edge while keeping the face square. As a result, the firing pin stop helps slow initial slide opening, improving recoil control and overall function. Simply put—it works.

Moreover, EGW Rockwell tests each firing pin stop to 48 Rc. This hardness ensures the part holds its shape under recoil and resists deformation over time. Although this firing pin stop does not drop in, proper fitting unlocks its full benefits and delivers noticeably improved performance.

This model fits Series 80 1911 pistols chambered in 9mm, .38 Super, .40 S&W, and 10mm, and it is cut for adjustable rear sights. Series 80 firing pin stops will also function in Series 70 pistols. However, Series 70 firing pin stops will not work in Series 80 guns.
