Overview of The Operating Cycle

The cycling of any type of semiautomatic firearm can be broken down into two phases; the first is the rearward motion of the bolt or slide (hereafter referred to only as slide, which is the most common form in pistols), the second is the forward motion of the slide. The rearward motion of the slide is initiated by the force of firing, and continues using the slide's inertia. While the slide moves rearwards, a spring, called the recoil spring, is compressed, absorbing the energy of the slide while slowing it down. Approximately 50% of the momentum imparted by the bullet and gas is converted into kinetic energy of the slide relative to the frame. This energy is stored by the recoil spring. The other approximate 50% of the momentum is converted to the kinetic energy by accelerating the hand and arm mass. During this phase the fired cartridge case is extracted from the barrel and ejected. When the slide is fully to the rear, it is stopped by the fully compressed recoil spring. The spring then pushes the slide forward, stripping a new cartridge from the magazine and pushing it into the chamber. The firearm is then ready to fire the next round.

Famous quotes containing the words operating and/or cycle:

    ... the modern drama, operating through the double channel of dramatist and interpreter, affecting as it does both mind and heart, is the strongest force in developing social discontent, swelling the powerful tide of unrest that sweeps onward and over the dam of ignorance, prejudice, and superstition.
    Emma Goldman (1869–1940)

    The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.
    Paula C. Lowe (20th century)
