Abstract

The invention relates to a trigger system for hand firearms with a hammer, a catch allocated to the hammer, a trigger, and a trigger arm interacting with this trigger, wherein the hammer has a first stop for holding the hammer in a completely cocked position and the trigger arm has a first trigger arm stop edge for engaging with an associated first hammer stop of the hammer. In order to allow pulling of the trigger with lower trigger weight even in the double-action mode, the hammer contains a second stop for holding the hammer in a partially pre-cocked position and the trigger arm has a second trigger arm stop edge for engaging an associated second hammer stop of the hammer.
