Self-contained fire control unit for striker-fired firearms

A fire control assembly for a striker-fired firearm having a striker, the fire control assembly comprising:

• a primary sear moveably mounted within a housing;
• and
• a striker-release member moveably mounted within the housing and configured to restrain a striker in a cocked position;
• wherein the primary sear and the striker-release member define a compound linkage in which the primary sear serves as a mechanical stop to prevent displacement of the striker-release member;
• and
• wherein, upon movement of the primary sear to an unlocked position, the striker-release member is configured to receive a biasing force from the striker to assist in displacing the striker-release member out of a longitudinal path of the striker via a translation, a rotation, or a combination thereof.

A fire control assembly for permitting rearward travel of a striker past a sear in a striker-fired firearm, the fire control assembly comprising:

• a primary sear and a striker-release member pivotally mounted within a housing;
• a secondary disconnector moveably seated within the housing;
• wherein the secondary disconnector is configured to translate in response to rearward pressure from a striker;
• and
• wherein the translation of the secondary disconnector rotates the primary sear to an unlocked position, thereby permitting the striker-release member to pivot out of a rearward travel path of the striker.
