The trigger mechanism of a hand-held automatic firearm comprises a catch lever, which is pivoted on a transverse axis and is provided at its forward end with a pivoted catch pawl, which in a catching position engages a catching lug of a slider to arrest the slider as it moves forwardly from a rear position, to which the slider, which constitutes a part of a firing mechanism of the firearm, has moved against spring force when a round has been discharged. In order to provide such a firearm which has a trigger mechanism which is reliable in operation and can be made at low cost, the catch lever is adapted to be locked in its catching position against the force of a catch lever spring, the catch pawl is pivoted to the catch lever by means which permit a longitudinal movement of the catch pawl and the catch pawl is pivotally supported at its other end on an abutment, which is fixed to the receiver of the firearm.
