Description

The firing pin stop is one of the most overlooked yet functional upgrades you can make to a Series 70 1911. This small steel plate sits at the rear of your slide, controlling firing pin travel while also influencing how your slide interacts with the hammer during the recoil cycle. The EGW oversized version addresses common issues that come with loose factory tolerances across different slide manufacturers.

How the EGW Oversized Firing Pin Stop Delivers Better Control

Standard firing pin stops are made to generic dimensions that work okay in some guns and loosely in others. The EGW oversized design is intentionally machined larger, giving you material to work with so you can fit it precisely to your specific slide. The wider profile prevents your extractor from rotating, which is a common problem that leads to inconsistent case ejection. The extra thickness eliminates side-to-side movement that factory parts allow, resulting in a tighter lockup and more predictable function throughout your shot string.

Performance Features Built Into This Design

The square edge bottom is where this part really shines for recoil control. Instead of the rounded profile most factory parts have, the EGW maintains a mostly square bottom with just a .015" micro radius to keep it from digging into your frame. That square edge contacts the hammer lower on its face during cycling, requiring the slide to work slightly harder when it recoils. This modest resistance slows your slide velocity enough to reduce felt recoil and muzzle flip without compromising reliability. The internal corners are radiused to prevent stress cracking during long-term use, and the whole part is hardness-tested to 48 Rc on the Rockwell scale.

Installation Notes

This is not a drop-in part. It comes oversized so you can file it to fit your particular slide, which typically takes 20-30 minutes. The payoff is a rock-solid fit that won't shift around. Once properly fitted, many users report a noticeably smoother recoil impulse and more reliable ejection. Series 70 firing pin stops work only in Series 70 1911s and clones, though Series 80 stops can be adapted to Series 70 guns if needed.

Frequently Asked Questions

Will this firing pin stop work with my Series 80 1911?

This stop is specifically designed for Series 70 pistols only. Series 80 firing pin stops can be adapted to work in Series 70 guns, but Series 70 stops do not work in Series 80 guns due to the different firing pin safety mechanism in Series 80 frames. Check your pistol's documentation to confirm which series you have.

Why is the EGW oversized firing pin stop not a drop-in fit?

It's oversized intentionally so you have material to work with and can fit it precisely to your individual slide. Since slide manufacturers use different tolerances, having extra material lets you achieve a tighter fit that eliminates slop. Most people spend 20-30 minutes fitting it with a file and some abrasive paper.

How does a square-bottom firing pin stop reduce recoil?

The square bottom edge contacts the hammer lower on its face than a rounded design, which means the slide has to work harder to cycle rearward. This slows slide velocity and reduces the force transferred to your hand. For Officers models especially, this can make a noticeable difference in felt recoil.

What does it mean that this prevents extractor clocking?

Extractor clocking is when the extractor rotates around the firing pin as the slide cycles, changing its grip angle on the fired case each time. The wider profile and thicker design of this EGW stop keep your extractor locked in place, so it maintains consistent tension and delivers predictable ejection every shot.
