In a hammerless automatic pistol with double-action and single-action functions there are provided between the trigger arm and firing pin of the trigger mechanism a catch pawl for the firing pin and a support lever that maintains the catch pawl in the catch position. During double-action operation, both of these intermediate components are disengaged but they are engaged for single-action function. The engagement and disengagement of these intermediate components is performed automatically during the shooting cycle. By merely removing one or both of these intermediate components the automatic pistol can be modified for double-action only trigger function, in which the firing pin is simultaneously cocked and released for firing during each shot by actuating the trigger.
A trigger mechanism for hammerless hand firearm comprising a trigger housing, a trigger pivotally mounted in a stock of the firearm, a trigger arm within said trigger housing and connected to and actuated by said trigger, an axially displaceable spring-loaded firing pin and a catch pawl to hold said firing pin in a cocked position, a support lever between said catch pawl and said trigger arm, said support lever engageable with and maintaining said catch pawl in a position for single-action operation and is disengageable for double-action operation.
A trigger mechanism for a hammerless hand firearm comprising a trigger housing, a trigger pivotally mounted in a stock of the firearm, a trigger arm within said trigger housing and connected to and actuated by said trigger, an axially displaceable spring-loaded firing pin, and means comprising at least one intermediate element engageable between said firing pin and said trigger arm for providing both double-action and single-action operation of the firearm, said intermediate element means is engageable and disengageable automatically during the combined double-action and single-action operation, and further comprising means for removing or inserting said intermediate element means to adapt from double-action and single-action function to only double-action operation and visa versa.
