EGW’s King’s Style 1911 Ambi Thumb Safety Stainless Steel

EGW King’s Style 1911 Ambidextrous Thumb Safety – Stainless Steel

Precision‑Machined Control for Serious 1911 Builds

The EGW King’s Style 1911 Ambi Thumb Safety in stainless steel delivers a robust, precision‑machined upgrade for shooters who demand reliability and control. Whether you are converting a single‑sided 1911 to an ambidextrous configuration or replacing a worn or broken safety, this design provides a stronger, cleaner, and more durable solution.

Unlike cast or MIM safeties that often fail under hard use, EGW machines this thumb safety entirely from solid steel. As a result, it offers superior strength, improved fit, and long‑term durability for duty, competition, and custom pistols alike.

Machined From Solid Steel for Maximum Strength

Built to Eliminate Common Ambi Safety Failures

EGW designed this ambidextrous thumb safety in response to consistent failures seen in inferior cast and MIM designs. Therefore, instead of cutting corners, EGW machines both paddles from solid blocks of heat‑treated stainless steel.

Moreover, EGW heat treats the steel before final machining. Because of this process, the safeties remain straight, dimensionally stable, and resistant to flex. Consequently, the finished part delivers consistent engagement and long‑term reliability.

In addition, the thumb pads feature precise serrations, which improve grip and control. As a result, engaging or disengaging the safety feels positive, repeatable, and confident under all conditions.

Advanced Ambidextrous Joint Design

Secure, Flat‑Machined Interface That Stays Tight

Rather than using a tapered ambi joint that can loosen over time, EGW machines a flat, non‑tapered joint between both sides of the safety. Because of this design choice, the two halves remain tightly engaged during extended use.

Furthermore, EGW incorporates a patent‑pending internal sleeve that joins both sides of the safety inside the frame tangs. As a result, the sleeve prevents expansion at the joint and effectively lengthens each side of the safety for improved rigidity and reduced flex.

At the same time, the grip safety rides on the round sleeve instead of the ambi joint. Therefore, operating the thumb safety does not influence grip safety movement, ensuring smooth and independent function of both components.

Precision‑Engineered Internal Components

Purpose‑Built Hardware for Proper Fit and Function

EGW includes specially manufactured internal components to ensure proper installation and long‑term reliability. Using Swiss screw machines, EGW produces the hammer pins, shortened flat‑headed .110 sear pin, and the patent‑pending sleeve. Each of these components undergoes heat treatment to maximize strength and durability.

Additionally, EGW supplies two special hammer pins for frames measuring .750″ to .765″ wide. Importantly, the hammer pin also acts as the down‑stop for the right‑side paddle. As a result, the right safety lever remains secure without relying on grip panels for retention.

Improved Frame and Safety Interaction

Designed to Protect Components and Maintain Alignment

On the left‑side safety lug, EGW machines a radius down‑stop instead of a pointed contact surface commonly found on other safeties. Because of this radius, the safety contacts the frame more evenly, which reduces wear and improves longevity.

Meanwhile, the T‑slot on the right‑hand side prevents the safety from walking out during use. Consequently, the ambi safety stays firmly in place, even under recoil and repeated manipulation.

Even better, this design eliminates the need to relieve or modify right‑side grip panels. Therefore, installation remains cleaner and more straightforward while preserving the appearance of your grips.

Fitting Requirements

Precision Parts Require Proper Gunsmith Fit

Although EGW machines this thumb safety to exacting standards, it is not a drop‑in part. As with all quality 1911 safeties, proper fitting is required to ensure correct engagement and safe operation. Consequently, final fitting should be performed by a knowledgeable gunsmith or experienced 1911 builder.
