Semiautomatic firearm

A firearm including a trigger assembly having passive and redundant safety mechanisms to prevent unintentional firing when the firearm is in a firing mode, the trigger assembly comprising:

• a hammer rotatable about a first axis, said hammer including structure defining a capture feature;
• a firing trigger component rotatable about a second axis and including a first finger hook portion, said firing trigger component including a sear portion releasably coupled to said hammer;
• and
• a safety trigger component rotatable about said second axis and including a second finger hook portion, said second finger hook portion extending adjacent to and forwardly of said first finger hook portion when said trigger assembly is in a battery position,
• wherein a first of said redundant safety mechanisms includes a catch portion defined on said safety trigger component and, when said safety trigger component is in a battery position, is positioned for arresting said capture feature of said hammer as said hammer rotates, to prevent discharge of said firearm,
• wherein a second of said redundant safety mechanisms includes a blocking member operatively coupled with said safety trigger component for maintaining said blocking member in a blocking position when said safety trigger component is in a battery position, said blocking member blocking said firing trigger component when in said blocking position to prevent release of said sear portion from said hammer, said blocking member being operatively coupled with said safety trigger component for moving said blocking member out of said blocking position by moving said safety trigger component out of said battery position to enable release of said sear portion from said hammer.
