EGW Oversized Firing Pin Stop Series 70 9/38 BL (Adj. Sight)

EGW Oversized Firing Pin Stop – Series 70 – 9mm / .38 Super / .40 / 10mm – Blued

Firing Pin Stop Cut for Adjustable Sights

Improve reliability and control with the EGW Oversized Firing Pin Stop for Series 70 1911 pistols. This upgraded part solves common extractor and slide issues that factory firing pin stops often create. As a result, your pistol ejects more consistently and cycles more smoothly.

First, EGW machines this firing pin stop wider than standard. This added width prevents the extractor from turning inside the slide. When the extractor stays in position, ejection becomes more reliable. Therefore, spent cases exit the pistol cleanly and predictably.

Next, EGW increases the overall thickness of the firing pin stop. This extra thickness eliminates side-to-side movement during recoil. Because the stop stays firmly in place, the slide cycles with better control and stability.

In addition, EGW radiuses the internal corners of the firing pin stop. Sharp corners often crack over time. By removing those stress points, EGW increases durability and extends service life. Consequently, the part handles high round counts without failure.

At the rear, EGW adds a .015-inch radius to break the sharp edge. However, the design keeps a square profile where it matters most. This shape slows initial slide opening and reduces battering. As a result, the pistol feels softer and more controlled during recoil.

Simply put, this firing pin stop works.

Furthermore, EGW hardens the part to 48 Rockwell C. This hardness resists peening and deformation. Even after long use, the stop holds its shape and continues to control the extractor properly.

Because this firing pin stop is intentionally oversized, it does not drop in. Instead, fitting is required. This fitting allows the part to lock tightly into the slide. Therefore, you gain every performance benefit EGW designed into the part.
