Safety mechanism for firearms

A firearm with dual-acting safety mechanism comprising:

• a longitudinal axis;
• a frame;
• a hammer pivotably movable in the frame, the hammer moveable between a rearward cocked position and a forward firing position;
• a sear pivotably movable in the frame and configured to hold the hammer in the rearward cocked position;
• a trigger mechanism comprising a pivotably movable trigger and a trigger bar movably coupled to the trigger, the trigger bar axially moveable via pulling the trigger to selectively engage and rotate the sear for releasing the hammer from the cocked position to discharge the firearm;
• a manually-operated safety mechanism comprising an axially slideable safety mode selector and a pivotably movable safety link, the safety link moveable between unactuated and actuated positions via sliding the actuator between first and second axial positions;
• the safety link comprising a first nose protrusion on one lateral side of the firearm which is selectively operable when the safety link is in the actuated position to engage and block rotation of the hammer to prevent discharging the firearm;
• the safety link further comprising a second foot protrusion on an opposite lateral side of the firearm which is selectively operable when the safety link is in the actuated position to engage and displace the trigger bar such that the trigger bar is prevented from engaging and rotating the sear to prevent discharging the firearm.

A dual-acting safety mechanism for a firearm having a firing mechanism with a rotatable hammer, a rotatable sear, and a trigger assembly including a trigger and trigger bar movably coupled thereto for fore and aft movement, the safety mechanism comprising:

• a longitudinal axis;
• a frame;
• a safety selector linearly movable in the frame between a forward position and a rearward position;
• a safety link pivotably movable in the frame and operably interfaced with the actuator, the safety link pivotably actuatable via moving the actuator between an upper position and a lower position;
• the safety link comprising a first lateral side including a first safety protrusion configured to selectively block rotational movement of the hammer when the safety link is actuated, and a second safety protrusion configured to selectively engage the trigger bar when the safety link is actuated;
• wherein the safety mechanism is changeable between a fire position in which the safety link is disengaged from the hammer and trigger bar which allows the firearm to be discharged in response to a trigger pull, and a safe position in which the safety link is engaged with the hammer and trigger bar to prevent the firearm from being discharged in response to a trigger pull.

A firearm with dual-acting safety mechanism comprising:

• a pivotable hammer;
• a rotatable sear operable to selectively hold the hammer in a cocked position;
• a trigger mechanism including a movable trigger and trigger bar which collectively operates to rotate the sear to release the hammer when in the cocked position;
• and
• a safety mechanism including a safety mode selector cooperating with a pivotably movable secondary safety link configured and operable to selectively engage the trigger bar and hammer;
• wherein linearly moving the selector actuates and rotates the safety link which simultaneously both blocks the hammer and displaces the trigger bar such that the sear can no longer be actuated via a trigger pull.
