Claim 7:
8. A firing mechanism, comprising:
a hammer pivotably mounted about a hammer axis;
a sear pivotably mounted about a sear axis, wherein the sear comprises a first hook operable to provide a primary interface with the hammer, wherein the sear further comprises a second hook operable to provide a secondary interface with the hammer, wherein the primary interface is a first distance from the sear axis and the secondary interface is a second distance from the sear axis, and further wherein the first distance is smaller than the second distance;
an actuator pivotably mounted about an actuator axis;
and
wherein the firing mechanism further comprises a trigger operable to rotate the actuator about the actuator axis to disengage the second hook of the sear from the actuator, thereby permitting the first hook of the sear to release the hammer and permit the firearm to be discharged, wherein, upon failure of the first hook, the second hook secures the hammer and prevents discharge of the firearm.
