摘要： A trigger mechanism includes a hammer element that has a ready position, an intermediate position, and a fired position. The hammer element includes a hammer sear and a notch positioned at a front of the hammer element. The trigger mechanism includes a trigger element has a ready position that retains the hammer element in the ready position. The trigger mechanism also includes a fired position that releases the hammer element. The trigger element includes a trigger sear that includes a hammer sear engagement zone and a notch engagement zone. When the hammer element is in the ready position, the trigger sear at least partially engages the hammer sear at the hammer sear engagement zone. When the hammer element is in the intermediate position, the trigger sear at least partially engages the notch at the notch engagement zone and not at the hammer sear engagement zone.

摘要： A roller sear/hammer interface for a firearm. The sear has a roller rotatably mounted between two side plates forming a portion of the sear body. As the trigger is moved, a linkage connecting the trigger and sear causes the sear to pivot rearward such that the roller engages a notched surface formed in the hammer. This rolling action releases the hammer to strike a firing pin to fire a round of ammunition. When the trigger is released, the sear roller rolls downward into an engaged and locked position within the notch formed in the hammer.
