Design
The Beretta 92's open slide design ensures smooth feeding and ejection of ammunition and allows easy clearing of obstructions. The hard-chromed barrel bore reduces barrel wear and protects it from corrosion. The falling locking block design provides good accuracy and operability with suppressors due to the in-line travel of the barrel. This is in contrast to the complex travel of Browning designed barrels. The magazine release button is reversible with simple field tools. Reversing the magazine release makes left-handed operation much easier.
Increasingly, it has become popular to reduce handgun weight and cost and increase corrosion resistance by using polymers. Starting around the year 2000, Beretta began replacing some parts with polymer and polymer coated metal. Polymer parts include the recoil spring guide rod which is now also fluted, magazine release button, magazine floor plate, magazine follower and the mainspring cap/lanyard loop. Polymer coated metal parts include the safety levers, trigger, trigger bar, slide lock/release and disassembly latch.
The 92 also spawned several variants of similar internal design. The Beretta 90two is a full-size variant of the 92-series with a redesigned slide and a redesigned aluminum frame with an internal recoil buffer, user changeable monogrips and an accessory rail.

Famous quotes containing the word design:
“I always consider the settlement of America with reverence and wonder, as the opening of a grand scene and design in providence, for the illumination of the ignorant and the emancipation of the slavish part of mankind all over the earth.”
—John Adams (1735–1826)
“We find that Good and Evil happen alike to all Men on this Side of the Grave; and as the principle Design of Tragedy is to raise Commiseration and Terror in the Minds of the Audience, we shall defeat this great End, if we always make Virtue and Innocence happy and successful.”
—Joseph Addison (1672–1719)
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
