Oversized Firing Pin Stop Series 80 – .45 ACP – Blued

Strengthen and tune your .45 ACP 1911 with the EGW Oversized Firing Pin Stop in blued carbon steel. This part targets one of the most critical control points in the 1911 design: extractor stability and slide timing. EGW machines this firing pin stop wider and thicker than factory parts, which allows you to fit it precisely to your slide for real performance gains.

Because the firing pin stop fits tighter, it prevents the extractor from rotating, also known as extractor clocking. When the extractor stays locked in the correct position, ejection becomes more consistent and reliable. At the same time, the increased thickness removes side‑to‑side movement, which further improves control during cycling.

EGW builds this firing pin stop from carbon steel and heat treats it to a Rockwell hardness of 48 Rc. This hardness level lets the part resist peening and deformation under recoil, even with heavy use. As a result, the stop holds its shape and maintains proper extractor alignment over a long service life.

To increase durability, EGW radiuses the internal corners. These smooth transitions reduce stress and help prevent cracking over time. In addition, the rear corner features a controlled .015‑inch radius. This design breaks the sharp edge while keeping a square profile. Because of this shape, the firing pin stop helps slow the initial slide movement, which can improve slide timing and soften the recoil impulse.

This firing pin stop does not drop in. Instead, it comes oversized so you can hand‑fit it to your slide. Once fit, it creates a solid interface between the slide, extractor, and firing pin. Builders, armorers, and competitive shooters rely on oversized firing pin stops for this reason—they deliver measurable improvements instead of cosmetic changes.

This model fits Series 80 .45 ACP 1911 pistols and will also function in Series 70 guns. However, Series 70 firing pin stops will not work in Series 80 pistols, so choosing the correct version matters.
