## Abstract

A trigger mechanism includes a hammer, and a trigger disconnector assembly including a trigger body having a trigger nose, and a disconnector having a disconnector hook. A reset lever is mounted for movement between open and closed positions. The trigger disconnector assembly is in mechanical communication with the reset lever. A striking end of the hammer strikes the reset lever in a past-cocked position of the hammer moving the reset lever from the open position to the closed position, the reset lever acting on the trigger disconnector assembly to reset the trigger body and the disconnector in the past-cocked position of the hammer in preparation for securing the hammer in a cocked position preparatory to firing by another trigger pull of the trigger body.

## Claims

### Claim 1

A trigger mechanism, comprising:
a trigger assembly, a reset lever, and a hammer, the trigger assembly moves between charged and discharged orientations, and the hammer moves between a firing position, a cocked position, and a past-cocked position;
the trigger assembly is in a hammer-engaging position, in the charged orientation of the trigger assembly;
the trigger assembly is in a hammer-releasing position, in the discharged orientation of the trigger assembly; and
the reset lever acts on the trigger assembly to move the trigger assembly from the discharged orientation to the charged orientation to position the trigger assembly in the hammer-engaging position for engaging the hammer in the cocked position of the hammer, in response to the hammer striking the reset lever in the past-cocked position of the hammer.

### Claim 2

A trigger mechanism, comprising:
a trigger assembly, a reset lever, and a hammer, the trigger assembly includes a disconnector hook and moves between charged and discharged orientations, and the hammer includes a hammer disconnect notch and moves between a firing position, a cocked position, and a past-cocked position;
the disconnector hook is in a disengaged position relative to the hammer disconnect notch, in the charged orientation of the trigger assembly;
the disconnector hook is in an engaged position relative to the hammer disconnect notch, in the discharged orientation of the trigger assembly; and
the reset lever acts on the trigger assembly to move the trigger assembly from the discharged orientation to the charged orientation to position the disconnector in the disengaged position of the disconnector hook relative to the hammer disconnect notch, in response to the hammer striking the reset lever in the past-cocked position of the hammer.

### Claim 3

A trigger mechanism, comprising:
a hammer, a trigger body having a trigger tail and a trigger nose for holding the hammer in a cocked position of the hammer in a set position of the trigger body and for releasing the hammer when the trigger body is moved a travel distance from the set position to a fired position of the trigger body, and a selector movable between a first position and a second position for adjusting the travel distance of the trigger body;
the selector has a first stop aligned with the tail of the trigger body in the first position, and a second stop aligned with the tail of the trigger body in the second position;
the first stop is separated from tail of the trigger body a first distance in the set position of the trigger body in the first position of the selector, and the second stop is separated from tail of the trigger body a second distance in the set position of the trigger body in the second position of the selector;
in the first position of the selector and the fired position of the trigger body the first distance between the first stop and the tail of the trigger body is closed and the tail contacts the first stop, and movement of the trigger body is arrested by the tail contacting the first stop;
in the second position of the selector and the fired position of the trigger body the second distance between the second stop and the tail of the trigger body is closed and the tail contacts the second stop, and movement of the trigger body is arrested by the tail contacting the second stop; and
the second distance is less than the first distance, wherein the travel distance of the trigger body in the second position of the selector is less than the travel distance of the trigger body in the first position of the selector.
