Magnetic trigger safety

摘要

A trigger safety blocks the tip of a trigger from behind except when the user of the firearm wear a ferromagnetic ring on his middle finger, or a glove containing a ferromagnetic insert. The ring or insert attracts a permanently magnetized arm pivotally mounted within a cavity in a trigger guard made of a non-magnetic material. An inconspicuous override button permits the owner of the firearm to disable the trigger safety when the ring or glove is not available.
