A light primer strike will result in a dead trigger and the gun will not cycle. This malfunction is not to be mistaken with a squib load which the gunpowder is ignited and the bullet fires, but is trapped in the barrel of a gun. A light primer strike will not have expanding gases as a squib load would produce as sign that there is one. A ...
The free-floating firing pin of AR-15 style rifles typically causes an indentation as the firing pin lightly strikes the primer when the bolt closes as it chambers a loaded cartridge. Although a single light indentation may not detonate the primer, [2] the indentation may make the primer more sensitive to subsequent impact. Some shooters avoid ...
In firearms and artillery, the primer (/ ˈ p r aɪ m ər /) is the chemical and/or device responsible for initiating the propellant combustion that will propel the projectiles out of the gun barrel.
The typical firing pin is a thin, simple rod with a hardened, rounded tip that strikes and crushes the primer. The rounded end ensures the primer is indented rather than pierced (to contain propellant gasses). It sits within a hole through the breechblock and is struck by the hammer when the trigger is "pulled". A light firing-pin spring is ...
Lock time or action time refers to the time interval (often measured in milliseconds) from when the trigger of a firearm is activated until the firing pin strikes the primer, and depends on the design of the firing mechanism. A long lock time increases the probability of the shooter pulling the sights away from the target before the bullet has ...
Conversely, unintentional pressure or a strike against the trigger is unlikely to do so, and such an action will not fire the firearm. Such a design, made popular by Glock pistols but originally used in the 1897 Iver Johnson Second Model Safety Hammerless revolver, incorporates a trigger with a spring-loaded lever in its lower half. This lever ...

Firearms use triggers to initiate the firing of a cartridge seated within the gun barrel chamber.This is accomplished by actuating a striking device through a combination of mainspring (which stores elastic energy), a trap mechanism that can hold the spring under tension, an intermediate mechanism to transmit the kinetic energy from the spring releasing, and a firing pin to eventually strike ...
