Single trigger dual firing mechanism

A single trigger dual firing mechanism having dual sears and dual hammers is provided. A pivoting connector link is mounted on a trigger with a horizontal pin. A selector bar causes the connector link to rotate to either engage the primary or secondary sear. Engagement of one sear locks the other sear and locks out the opposite hammer. When the selector turns and engages the primary sear then that sear is moved and the primary sear allows the primary hammer to fall. With the selector knob in the opposite position, the secondary sear is operated allowing the secondary hammer to move. The primary hammer is a swing type hammer. The secondary hammer is a piston type hammer. Both hammers operate from a single trigger using a thumb operatable selector bar.
