Abstract
A trigger mechanism for a firearm includes a sear which interacts with a trigger. The sear and trigger are held in contact by a sear block. The sear block has dogs which engage respective locking surfaces on the sear and trigger. Pivoting motion of the sear block disengages the dogs from the trigger and sear and allows the trigger to pivot and release the sear to discharge the firearm. When the dogs are engaged with the sear and trigger the resistance to inadvertent discharge due to inertial loads imposed on the mechanism when the firearm is dropped is increased.
