Abstract

Linear trigger mechanisms for firearms include a trigger slide mounted on, and configured to move linearly in relation to a chassis; and a hammer. The trigger slide has a rolling element, such as a pin-mounted roller or a rolling pin, that engages a contact surface on the hammer and thereby restrains the hammer against its spring bias. When the user pulls the trigger to discharge the firearm, the trigger slide moves linearly, causing the rolling element to roll off of the contact surface and thereby release the hammer. The trigger mechanisms can be equipped with a drop safety that rotates in response to an impact between the firearm and the ground, so as to interfere with the movement of the trigger slide and prevent the release of the hammer.
