The EGW Heavy-Duty (HD) Firing Pin is precision-machined to a .066" diameter, a common specification for modern 9mm and .38 Super slides.

1911 Firing Pin FAQ
Why are there different firing pin diameters?
Over the history of the 1911, different manufacturers have used different firing pin diameters for various reasons, often related to caliber. For example, .092" was common for .45 ACP, while smaller diameters like .066", .075" or .068" became popular for 9mm and .38 Super to increase breech face strength. It is critical to match the firing pin diameter to your slide's firing pin hole.

Fits perfectly and cured the 1-2% fail-to-fire problem I was having with my 9mm Springfield Range Officer.

For my build, this firing pin was exactly what I needed for the slide I was installing. Many vendors are downsizing from the original GI spec, and this pin fit and works flawlessly.
