Sear shown in a revolver action. In a firearm, the sear is the part of the trigger mechanism that holds the hammer, striker, or bolt back until the correct amount of pressure has been applied to the trigger, at which point the hammer, striker, or bolt is released to discharge the weapon. The sear may be a separate part or can be a surface ...
Auto sear. An auto sear ("automatic sear ") is a part of an automatic firearm that holds the hammer in the cocked position while the bolt of the weapon is cycling. An auto sear is required in nearly every automatic rifle. An auto sear allows a semi-automatic gun to be converted into one capable of automatic firing with a single, continuous pull ...
A Glock switch (sometimes called a button or a giggle switch) [1][2][3] is a small device that can be attached to the rear of the slide of a Glock handgun, converting the semi-automatic pistol into a selective fire machine pistol capable of fully automatic fire. As a type of auto sear, it functions by applying force to the trigger bar to ...
Speargun in use by a diver. A speargun is a ranged underwater fishing device designed to launch a tethered spear or harpoon to impale fish or other marine animals and targets.

Previously the sear, located within the lock, had acted through a hole in the lockplate to engage the cock on the outside of ...
Open bolt. A MAC-10 submachine gun. A firearm is said to fire from an open bolt or open breech if, when ready to fire, the bolt and working parts are held to the rear of the receiver, with no round in the chamber. When the trigger is actuated, the bolt travels forward, feeds a cartridge from the magazine or belt into the chamber, and fires that ...
The movement of the sear is nominally parallel to the axis of rotation of the cock. Depressing the trigger causes the sear to be drawn inward and release the cock. This type of sear was used in firelocks prior to the advent of the true flintlock. The next advance in firearm design was the snaplock, which used flint striking steel to generate ...
With the Italian or Roman style miquelet lock, the mainspring pushes down on the toe of the hammer and the sears engaged the hammer on both the toe and heel. Miquelet lock is a modern term used by collectors and curators for a type of firing mechanism used in muskets and pistols. It is a distinctive form of snaplock, originally as a flint ...
