Frequently Asked Questions
Is the Glock Switch Purple Color – Auto Sear legal to own?
In the United States, an auto sear, when installed in a semi-automatic firearm, converts that firearm into a machine gun. Unlicensed possession of a machine gun is illegal under federal law (National Firearms Act, 26 U.S.C. § 5801 et seq.). This product is intended for licensed manufacturers, dealers, or individuals with proper NFA registration for machine guns only. Always consult local and federal laws.
What Glock models are compatible with this auto sear?
This auto sear is designed for compatibility with Glock Gen 3, 4, and 5 pistols, including most full-size and compact models. It is generally not compatible with single-stack models like the Glock 43 or 48 due to frame size differences.
Can I install this auto sear myself?
While the physical installation might seem straightforward to someone familiar with Glock disassembly, installing this component converts a firearm into a machine gun, which has severe legal ramifications. Professional installation by a licensed individual with proper NFA authorization is recommended, primarily to ensure compliance and safe operation if legally permitted.
What is the purpose of the purple color?
The purple color is purely aesthetic. It offers a unique and distinct visual appearance, allowing for customization beyond standard black or metallic finishes. It does not affect the function of the auto sear.
