Revolver
A revolver (also called a wheel gun) is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold up to six rounds of cartridge before needing to reload, revolvers are also commonly called six shooters. Before firing, cocking the revolver's hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. The hammer cocking in nearly all revolvers are manually driven, and can be achieved either by the user using the thumb to directly pull back the hammer (as in single-action), via internal linkage relaying the force of the trigger-pull (as in double-action), or both (as in double/single-action). By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-sho ...

Colt Trooper
The Colt Trooper is a medium frame, double-action revolver featuring a six-round cylinder, chambered for .22 Long Rifle, .22 Winchester Magnum Rimfire, .38 Special, and .357 Magnum caliber cartridges. Designed as a less expensive alternative to the upscale Colt .357 and the later Colt Python and Colt King Cobra, it was marketed to law enforcement agencies as well as civilians. Development and history Introduced to the firearms market by the Colt's Manufacturing Company in 1953, the Trooper and its high-end cousin, the .357 Magnum, were introduced with the intention of addressing the medium frame revolver market, as law enforcement officers had long complained about the weight of earlier models. The two guns were seen as ideal in size and handling characteristics for the .38 Special and its big brother the .357. Offered as an alternative and competitor to Smith & Wesson’s Model 28 "Highway Patrolman", the Colts were lighter and handier. Variants Trooper 1953 – 1969 The o ...

Hammer (firearm)
The hammer is a part of a firearm that is used to strike the percussion cap/ primer, or a separate firing pin, to ignite the propellant and fire the projectile. It is so called due to the fact that it resembles a hammer in both form and function. The hammer itself is a metal piece that forcefully rotates about a pivot point. Evolution Firearms, initially known as "hand cannons", first became a viable weapon in 1364 through the advancement of chemical technologies to create a gunpowder efficient enough to launch a projectile at high speeds in a hand-held weapon. The issue quickly arose of how to effectively ignite the gunpowder while maintaining the weapon’s aim at the target. Initially, the problem was solved by using a " slow match": a chemically treated piece of rope that would stay lit for an extended period of time. The smoldering end of the rope would then be manually brought into contact with the gunpowder through a touch hole in the barrel of the weapon. when the use ...

Bullseye (shooting Competition)
NRA Precision Pistol, formerly known as NRA Conventional Pistol, is a national bullseye shooting discipline organized in the United States by the National Rifle Association of America. Emphasis is on accuracy and precision, and participants shoot handguns at paper targets at fixed distances and time limits. Other organizations in the United States and Canada have established rules and keep records of similar disciplines, including the Civilian Marksmanship Program (CMP) in the United States. Bullseye pistol was the inspiration for the ISSF international 25 m Standard Pistol (82 feet) event and like the ISSF pistol events, the development of skills required to shoot one-handed at and bullseye targets at , respectively, takes considerable training to achieve proficiency. Courses of fire All courses of fire are from a standing position using a one-handed grip at two different targets depending on the distance and type of match. The slow-fire targets have the 8–10 rin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistol Grip
On a firearm or other tools, a pistol grip is a distinctly protruded handle underneath the main mechanism, to be held by the user's hand at a more vertical (and thus more ergonomic) angle, similar to the how one would hold a conventional pistol. In firearms, the pistol grip is located behind the trigger and generally held by the hand that operates the trigger. Rifles and shotguns without pistol grips are generally referred to as having "straight" or "upland" (shotguns only) style stocks. Some firearms, starting from a 1840s Belgian carbine,https://littlegun.be/arme%20belge/artisans%20identifies%20l/a%20lesoinne%20et%20pirlot%20gb.htm and most automatic weapons in the 20th century (e. g., Chauchat MG, Thompson submachine gun, AK-47 assault rifle), have a second frontal pistol grip (or foregrip) on the firearm's fore-end to be used by the support hand for better stability in operation. Pistol grips can also serve multiple functions, such as a magazine housing (in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combat
Combat (French for ''fight'') is a purposeful violent conflict meant to physically harm or kill the opposition. Combat may be armed (using weapons) or unarmed ( not using weapons). Combat is sometimes resorted to as a method of self-defense, or can be used as a tool to impose one's will on others. An instance of combat can be a stand-alone confrontation or a small part of a much larger violent conflict. Instances of combat may also be benign and recreational, as in the cases of combat sports and mock combat. Combat may comply with, or be in violation of local or international laws regarding conflict. Examples of rules include the Geneva Conventions (covering the treatment of people in war), medieval chivalry, the Marquess of Queensberry rules (covering boxing) and several forms of combat sports. Hand-to-hand combat Hand-to-hand combat ( melee) is combat at very close range, attacking the opponent with the body (striking, kicking, strangling, etc.) and/or with a mele ...

Accurizing
Accurizing is the process of improving the accuracy and precision of a gun ( firearm or airgun). For firearms, accuracy is the ability to hit exactly what one is aiming at, and precision is the ability to hit the same place over and over again in a repeatable fashion. Both are the goals of accurizing, which generally concentrates on four different areas: *Usability: Enhancements that give the shooter a firmer and more controlled hold on the firearm, as well as a more consistent trigger pull. Better design ergonomics is often employed, such as adjustable buttstocks and grips with more vertical angles that are natural to the human hand and wrist (e.g. pistol grip). Spirit levels are often mounted to prevent canting, which can vary the points of impact. Weapon mounts such as bipods, monopods, benchrests, shooting sticks or simply sandbags can provide a more stable and relaxed platform for the shooter, and devices such as muzzle brakes or compensators can also be used to help ...

Walnut
A walnut is the edible seed of a drupe of any tree of the genus '' Juglans'' (family Juglandaceae), particularly the Persian or English walnut, '' Juglans regia''. Although culinarily considered a "nut" and used as such, it is not a true botanical nut. After full ripening, the shell is discarded and the kernel is eaten. Nuts of the eastern black walnut ('' Juglans nigra'') and butternuts ('' Juglans cinerea'') are less commonly consumed. Characteristics Walnuts are rounded, single-seeded stone fruits of the walnut tree commonly used for food after fully ripening between September and November, in which the removal of the husk at this stage reveals a browning wrinkly walnut shell, which is usually commercially found in two segments (three or four-segment shells can also form). During the ripening process, the husk will become brittle and the shell hard. The shell encloses the kernel or meat, which is usually made up of two halves separated by a membranous partition. ...

Royal Blue
Royal blue is a deep and vivid shade of blue. It is said to have been created by clothiers in Rode, Somerset, a consortium of whom won a competition to make a dress for Queen Charlotte, consort of King George III. Brightness The ''Oxford English Dictionary'' defines "royal blue" as "a deep vivid blue", while the ''Cambridge English Dictionary'' defined it as "a strong, bright blue colour", and the ''Collins English Dictionary'' defines it as "a deep blue colour". US dictionaries give it as further towards purple, e.g. "a deep, vivid reddish or purplish blue" (''Webster's New World College Dictionary'') or "a vivid purplish blue" (''Merriam-Webster''). By the 1950s, many people began to think of royal blue as a brighter color, and it is this brighter color that was chosen as the web color "royal blue" (the web colors when they were formulated in 1987 were originally known as the X11 colors). The World Wide Web Consortium designated the keyword "royalblue" to be this much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal Polishing
Polishing and buffing are finishing processes for smoothing a workpiece's surface using an abrasive and a work wheel or a leather strop. Technically, ''polishing'' refers to processes that uses an abrasive that is glued to the work wheel, while ''buffing'' uses a loose abrasive applied to the work wheel. Polishing is a more aggressive process, while buffing is less harsh, which leads to a smoother, brighter finish.Oberg, p. 1439. A common misconception is that a polished surface has a mirror-bright finish, however, most mirror-bright finishes are actually buffed. Polishing is often used to enhance the appearance of an item, prevent contamination of instruments, remove oxidation, create a reflective surface, or prevent corrosion in pipes. In metallography and metallurgy, polishing is used to create a flat, defect-free surface for examination of a metal's microstructure under a microscope. Silicon-based polishing pads or a diamond solution can be used in the polishing process. Po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Steel
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: * no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added to obtain a desired alloying effect; * the specified minimum for copper does not exceed 0.40%; * or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65%; silicon 0.60%; copper 0.60%. The term ''carbon steel'' may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. High carbon steel has many different uses such as milling machines, cutting tools (such as chisels) and high strength wires. These applications require a much finer microstructure, which improves the toughness. Carbon steel is a popular met ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SAE Steel Grades
The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar and overlapped significantly. For several decades the systems were united into a joint system designated the AISI/SAE steel grades. In 1995 the AISI turned over future maintenance of the system to SAE because the AISI never wrote any of the specifications. Today steel quotes and certifications commonly make reference to both SAE and AISI, not always with precise differentiation. For example, in the alloy/grade field, a certificate might refer to "4140", "AISI 4140", or "SAE 4140", and in most light-industrial applications any of the above is accepted as adequate, and considered equivalent, for the job at hand, as long as the specific specific ...
