The EGW HD Ambi Thumb Safety in blued steel is built for shooters who demand reliability from their 1911 platform pistol. Unlike the cast and MIM safeties that dominate the market, EGW machines this ambidextrous thumb safety from solid steel bar stock and heat treats it before final machining—a process that eliminates the weakness and inconsistency found in inferior alternatives. The result is a safety that stays true, functions smoothly, and won't fail you on the range or in the field.
The dual-paddle design gives left- and right-handed shooters equal control, with serrated surfaces on both sides for positive grip and consistent manipulation under stress. EGW's patent-pending internal sleeve joins the safety paddles inside the frame tangs, preventing the common problem of side-to-side flex and creep that makes other safeties unreliable over time. The flat-machined ambi joint (not tapered) resists loosening, and the sleeve itself prevents the safety from expanding where the sides meet. A T-slot on the right side keeps the safety locked in place without the need to relieve your grips.
This is a premium component that requires professional fitting to your specific 1911—it's not a drop-in part. The package includes both left and right side safeties, matched hammer pins (.797" and .807"), a shortened sear pin, and the safety sleeve. Installation should be handled by someone familiar with 1911 gunsmithing or by a qualified armorer to ensure proper function and safety.
If you're rebuilding a 1911 or upgrading from an unreliable factory safety, the EGW HD Ambi offers the durability and precision that serious shooters expect from a hardened steel component.

Frequently Asked Questions
Will this safety fit my 1911 without gunsmithing?
No. EGW states this safety requires fitting for proper function in your 1911 and is not a drop-in part. Professional fitting by a gunsmith or armorer familiar with 1911s is recommended.
Why does this safety come with two different hammer pins?
The two hammer pins (.797" and .807") are included to accommodate fitting during installation. Your gunsmith will determine which pin is correct for your specific 1911.
Can both right- and left-handed shooters use this safety?
Yes. The EGW HD is an ambidextrous design with serrated paddles on both the left and right side, making it equally accessible to shooters of either hand orientation.
What makes this safety more reliable than standard cast or MIM safeties?
EGW machines this safety from solid steel bar stock and heat treats it in the hardened state before final machining. This process produces a stronger component than cast or MIM (metal injection molded) safeties, which are prone to failures and inconsistency. The patent-pending internal sleeve also prevents the flex and creep that causes other safeties to loosen over time.
