A firing mechanism for firearms in which the sear spring is mounted so that its point of engagement with the sear can be switched farther from, or nearer to, the pivotal axis of the sear in order to increase or decrease the trigger pull. The sear spring is also mounted so that when the firing mechanism is used in a lever action, the sear spring also urges the latch for the finger lever into latching position. A disconnector is pivoted on the sear for rotation in one direction only with respect thereto, so that when the trigger engages the engagement surface on the disconnector, the firing mechanism is operable. After the gun is fired and while the trigger is pulled, the actuating lug on the trigger engages a convex surface on the underside of the disconnector pivoting it on the sear out of its operative position with respect thereto.
