What action follows the squeezing of the trigger in firing a firearm?

When the trigger of a firearm is squeezed, the action that follows is the releasing of the firing mechanism. This action is crucial in the firing sequence. Squeezing the trigger typically leads to the disengagement of the sear, which releases the firing pin or striker, allowing it to impact the primer of the cartridge. This ignites the propellant, leading to the discharge of the bullet.

Chambering a new round, extracting an empty case, and ejecting the magazine are actions that occur in different phases of handling a firearm. For instance, chambering a new round happens before the trigger is squeezed, during preparation for firing. Extracting an empty case occurs after the shot is fired, as part of the ejection process, and ejecting the magazine is generally related to reloading or safety procedures, not the immediate firing action. Thus, the release of the firing mechanism directly follows the trigger squeeze and is a fundamental step in the firing process.
