Upgrade the safety mechanism on your 1911 or 2011 pistol with the Evolution Gun Works EGW HD Ambi Thumb Safety. Machined from solid barstock of heat-treated carbon steel and finished in durable blue, this ambidextrous thumb safety delivers superior strength and reliability compared to cast or MIM alternatives that can fail under stress.
Key Features and Benefits
- Machined from solid barstock – Eliminates weak points found in inferior cast or molded parts, providing exceptional durability for consistent performance in demanding applications.
- Patented sleeve design – The innovative sleeve joins both sides inside the frame tangs, prevents expansion, reduces flex, and ensures secure operation while allowing the grip safety to function independently.
- Serrated paddles – Each paddle measures 0.328 inches wide and features serrations for enhanced grip and positive engagement, even with gloves or under rapid manipulation.
- Precision engineering details – Includes a flat-machined joint (not tapered), radius down stop on the left side, and t-slot on the right to prevent walking out, plus compatibility with frames measuring .750 to .765 inches wide via included hammer pins.
