Abstract
In some embodiments, a trigger group comprises a trigger arranged to pivot on a trigger axis and a hammer arranged to pivot on a hammer axis. The hammer includes a cam surface. The hammer is moveable from a first position to a second position upon break of the trigger, and the cam surface contacts the trigger in the second position. Desirably, the cam is arranged to bias the trigger.
Claims16
A trigger group comprising:
- a trigger arranged to pivot on a trigger axis, said trigger comprising a trigger sear and a following portion, said trigger sear abutting said following portion;
- and
- a hammer arranged to pivot on a hammer axis, said hammer comprising a cam surface, a hammer sear and an extension lobe, said extension lobe comprising a secondary contact point;
- wherein said hammer is moveable from a first position to a second position upon break of said trigger, said trigger sear contacting said hammer sear in said first position, said secondary contact point in contact with said trigger in said first position, said secondary contact point setting a predetermined amount of trigger creep to break, said cam surface contacting said following portion in said second position.
