A trigger mechanism or fire control for trigger operable devices includes a housing; a sear having a sear body coupled to the housing and including a primary engagement surface and an active sear support reset geometry; and a sear support coupled to the housing and having a body with a sear engagement surface and a passive sear support reset geometry. The primary engagement surface of the sear is moved into an overlapping condition with the sear engagement surface of the sear support as the sear is moved from a discharged position to a reset position after actuation of the trigger operable device. In addition, interaction between the active sear support reset geometry and the passive sear support reset geometry causes a mechanical displacement of the sear support to a reset position.

Provided is a trigger mechanism having a housing, a trigger member, a trigger dog, and a striker dog. The trigger member is pivotally mounted in the housing, movable between set and pulled positions. The trigger dog is pivotally mounted in the housing and a first lever arm portion of the trigger dog engages a lever arm portion of the trigger member by a first over-center linkage. The striker dog is pivotally mounted in the housing, movable between set and released positions with a lever arm portion engaged to a second lever arm portion of the trigger dog by a second over-center linkage. The over-center linkages are configured to inhibit rotation of the striker dog from the set position to the released position until the trigger member is manipulated from the set position to the pulled position with a force greater than an engagement threshold of the over-center linkages.

The invention relates to a chambering device (1) for chambering rounds in an automatic firearm, which has a breechblock (119, 172) that can move longitudinally in a receiver (3), comprising: a loading lever (13, 13), comprising a loading lever handle (15) coupled to a loading lever retainer (17), and a loading lever housing (59, 59), which can move longitudinally in the receiver (3). The chambering device is characterized in that the loading lever handle (15) can be pivoted from a standby position to an actuation position and back in the loading lever retainer (17), and the loading lever retainer (17) can be mounted in or on the left or right side the loading lever housing (59, 59) and can be removed therefrom without tools. The invention also relates to an automatic firearm equipped with such a chambering device (1).
