Oversized Firing Pin Stop – Series 70 – .45 ACP – Stainless Steel

Precision Upgrade for Serious 1911 Builds

Improve the reliability and consistency of your Series 70 1911 with the EGW Oversized Stainless Steel Firing Pin Stop. This precision component addresses extractor instability and slide timing issues that factory firing pin stops often allow. Although small, this part plays a major role in how smoothly and reliably your pistol cycles.

Oversized Design Improves Extractor Control

EGW machines this firing pin stop wider than standard to prevent extractor clocking. As a result, the extractor stays properly aligned during cycling. This alignment improves ejection consistency and helps prevent erratic extraction. In addition, the increased thickness removes lateral movement, giving the slide better control under recoil.

Optimized Slide Timing and Reduced Wear

The rear edge features a precise .015-inch radius. This design softens the corner without rounding it excessively. Consequently, the slide opens more gradually, which helps reduce frame and slide battering. Slower initial slide movement also improves overall timing, especially in pistols tuned for reliability or competition use.

Radiused Corners for Long Service Life

EGW radiuses the internal corners to reduce stress and prevent cracking. This attention to detail greatly extends the service life of the firing pin stop, even under high round counts and hard use. For shooters who train often or compete regularly, this added durability matters.

Heat Treated and Rockwell Tested

EGW heat treats each firing pin stop and Rockwell tests it to 48 Rc. This hardness allows the part to hold its shape and resist peening over time. Because the stop is oversized, it requires fitting. However, proper fitting creates a tight, custom fit that delivers the performance gains this design offers.

Compatibility and Fit Notes

This firing pin stop fits Series 70 .45 ACP 1911 pistols. Series 80 firing pin stops will work in Series 70 guns, but Series 70 firing pin stops will only work in Series 70 pistols. Always confirm your pistol’s series before ordering.
