92fs
The Beretta 92 (also Beretta 96 and Beretta 98) is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. The Beretta 92 was designed in 1975, and production began in 1976. Many variants in several different calibers continue to be used to the present. The United States military replaced the .45 ACP M1911A1 pistol in 1985 with the Beretta 92FS, designated as the " M9." History The Beretta 92 pistol evolved from earlier Beretta designs, most notably the M1923 and M1951. From the M1923 comes the open slide design, while the alloy frame and locking block barrel, originally from Walther P38, were first used in the M1951. The grip angle and the front sight integrated with the slide were also common to earlier Beretta pistols. What were perhaps the Model 92's two most important advanced design features had first appeared on its immediate predecessor, the 1974 .380 caliber Model 84. These improvements both involved the magazine, which featured direct feed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beretta M9
The Beretta M9, officially the Pistol, Semiautomatic, 9mm, M9, is the designation for the Beretta 92FS semi-automatic pistol used by the United States Armed Forces. The M9 was adopted by the United States military as their service pistol in 1985. The 92FS won a competition in the 1980s to replace the M1911A1 as the primary sidearm of the U.S. military, beating many other contenders, and only narrowly defeating the SIG Sauer P226 for cost reasons. It officially entered service in 1990. Some other pistols have been adopted to a lesser extent, namely the SIG P228 pistol, and other models remain in use in certain niches. The M9 was scheduled to be replaced under a United States Army program, the ''Future Handgun System'' (FHS), which was merged with the ''SOF Combat Pistol'' program to create the '' Joint Combat Pistol'' (JCP). The JCP was renamed ''Combat Pistol'' (CP), and the number of pistols to be bought was drastically cut back. The U.S. Army, Navy, Air Force, and Marine C ...

Walther P38
The Walther P38 (originally written Walther P.38) is a 9 mm semi-automatic pistol that was developed by Carl Walther GmbH as the service pistol of the Wehrmacht at the beginning of World War II. It was intended to replace the costly Luger P08, the production of which was scheduled to end in 1942. Development The first designs was submitted to the German Army and featured a locked breech and a hidden hammer, but the Army requested that it should be redesigned with an external hammer. The P38 concept was accepted by the German military in 1938 but production of prototype ("Test") pistols did not begin until late 1939. Walther began manufacture at their plant in Zella-Mehlis and produced three series of "Test" pistols, designated by a "0" prefix to the serial number. The third series pistols satisfactorily solved the previous problems for the German Army and mass production began in mid-1940, using Walther's military production identification code "480".

Tellurium
Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens. It is occasionally found in native form as elemental crystals. Tellurium is far more common in the Universe as a whole than on Earth. Its extreme rarity in the Earth's crust, comparable to that of platinum, is due partly to its formation of a volatile hydride that caused tellurium to be lost to space as a gas during the hot nebular formation of Earth.Anderson, Don L.; "Chemical Composition of the Mantle" in ''Theory of the Earth'', pp. 147-175 Tellurium-bearing compounds were first discovered in 1782 in a gold mine in Kleinschlatten, Transylvania (now Zlatna, Romania) by Austrian mineralogist Franz-Joseph Müller von Reichenstein, although it was Martin Heinrich Klaproth who named the new element in 1798 after the Latin 'earth'.

Beretta 92FS Left
Fabbrica d'Armi Pietro Beretta (; "Pietro Beretta Weapon Factory") is a privately held Italian firearms manufacturing company operating in several countries. Its firearms are used worldwide for a variety of civilian, law enforcement, and military purposes. Sporting arms account for three-quarters of sales; Beretta is also known for marketing shooting clothes and accessories. Founded in the 16th century, Beretta is the oldest active manufacturer of firearm components in the world. In 1526 its inaugural product was arquebus barrels; by all accounts Beretta-made barrels equipped the Venetian fleet at the Battle of Lepanto in 1571. Beretta has supplied weapons for every major European war since 1650. History Val Trompia, a northern Italian river valley in the Province of Brescia, Lombardy, has been mined for iron ore since the time of the Roman Empire. In the Middle Ages, Val Trompia was known for its ironworks; after the Renaissance it came to be a center for the manufacture o ...

Bluing (steel)
Bluing is a passivation process in which steel is partially protected against rust using a black oxide coating. It is named after the blue-black appearance of the resulting protective finish. Bluing involves an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the surface selectively forming magnetite (), the black oxide of iron. In comparison, rust, the red oxide of iron (), undergoes an extremely large volume change upon hydration; as a result, the oxide easily flakes off causing the typical reddish rusting away of iron. Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic action. In colloquial use, thin coatings of black oxide are often termed 'gun bluing', while heavier coatings are termed 'black oxide'. Both refer to the same chemical process for providing true gun bluing. Overview Various processes are used for the oxidizing process. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hard Chromed
Chrome plating (less commonly chromium plating) is a technique of electroplating a thin layer of chromium onto a metal object. A chrome-plated item is called ''chrome''. The chromed layer can be decorative, provide corrosion resistance, ease of cleaning, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes. Process Chrome plating a component typically includes these stages: * Degreasing to remove heavy soiling * Manual cleaning to remove all residual traces of dirt and surface impurities * Various pretreatments depending on the substrate * Placement into the chrome plating vat, where it is allowed to warm to solution temperature * Application of plating current for the required time to attain the desired thickness There are many variations to this process, depending on the type of substrate being plated. Different substrates need different etching solutions, such as hydrochloric, hydrofluoric, and sulfuric acids. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iron Sights
Iron sights are a system of physical alignment markers (usually made of metallic material) used as a sighting device to assist the accurate aiming of ranged weapons (such as a firearm, airgun, crossbow or even compound bow), or less commonly as a primitive finder sight for optical telescopes. The earliest sighting device, it relies completely on the viewer's naked eye (mostly under ambient lighting), and is distinctly different to optical sights such as telescopic sights, reflector (reflex) sights, holographic sights and laser sights, which make use of optical manipulation and/or active illumination, as well as the newer optoelectronics, which use digital imaging and even incorporate augmented reality. Iron sights are typically composed of two components mounted perpendicularly above the weapon's bore axis: a rear sight nearer (or ''proximally'') to the shooter's eye, and a front sight farther forward (or ''distally'') near the muzzle. During aiming, the shooter al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
