  • Patent number: 3983654
    Abstract: A release trigger arrangement for a firearm having a frame, a spring-loaded hammer mounted on the gun receiver and movable between a cocked position and a firing position and a movable, spring-loaded trigger for moving a sear out of such cocking engagement with the hammer against the urging of the spring-loading of the trigger. A first engagement member is mounted on the hammer. A second engagement member is mounted in spaced relation from the first engagement member when the sear is in cocking engagement with the hammer. The second engagement member is movable in response to a movement of the trigger against the urging of the spring-loading thereof into engagement with the first engagement member just prior to a release of the hammer by the sear to prevent a movement of the hammer to the firing position. The second engagement member is disengaged from the first engaging member in response to a movement of the trigger solely as a result of the spring-loading thereof.
