Ruger Speed-Six
The Ruger Security-Six and its variants, the Service-Six and Speed-Six are a product line of Trigger (firearms)#Double-action, double-action revolvers introduced in 1972 and manufactured until 1988 by Sturm, Ruger & Co. These revolvers were marketed to law enforcement Service Pistol, duty issue, military, and civilian self-defense markets. Development and history As far back as 1966, Ruger designers Harry Sefried and Henry Into began working on the company's first double-action revolver. Despite being popular with civilians, founder Bill Ruger hoped to expand into the law enforcement and private security markets, which were then dominated by rivals Smith & Wesson and Colt's Manufacturing Company, Colt. The introduction of the Security-Six and its variants marked Sturm Ruger's first attempt to sell a custom double-action revolver, deviating from the corporation's earlier designs which were outdated Colt Peacemaker-style Trigger (firearms)#Single action, single-action revolvers.

Revolver
A revolver is a repeating handgun with at least one barrel and a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold six cartridges before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns. 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. By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot firearms that had to be reloaded after each shot. The hammer cocking in nearly all revolvers is manually driven and can be cocked either by the user using the thumb to directly pull back the hammer (as in single-action), or via internal linkage relaying t ...

High Standard
High Standard Firearms was an American manufacturer of firearms, based in Houston, Texas. The company was founded in New Haven, Connecticut, in 1926 as a supplier to the numerous firearms companies in the Connecticut Valley. It was based in New Haven from 1932-1945, at which time it was relocated to suburban Hamden, CT, where it continued to manufacture firearms from 1946 through 1977, at which time it moved to East Hartford, CT, from 1977-1984. History In 1932, the company, headed by Carl Gustav Swebilius, purchased the Hartford Arms and Equipment Company and began making .22 caliber pistols. During World War II, the company supplied .22 caliber pistols for basic pistol training and familiarization to the armed forces. At the request of Office of Strategic Services Deputy Director for Research and Development Stanley P. Lovell, the company also developed a silent, flashless pistol for use by OSS agents behind enemy lines. An example of the pistol can be seen at the Franklin De ...

Centerfire
Two rounds of .357 Magnum, a centerfire cartridge; notice the circular primer in the center A center-fire (or centerfire) is a type of metallic cartridge used in firearms, where the primer is located at the center of the base of its casing (i.e. "case head"). Unlike rimfire cartridges, the centerfire primer is typically a separate component seated into a recessed cavity (known as the ''primer pocket'') in the case head and is replaceable by reloading the cartridge. Centerfire cartridges have supplanted the rimfire cartridge, with the exception of a few small calibers. The majority of today's handguns, rifles, and shotguns use centerfire ammunition, with the exception of some .17 caliber, .20 caliber, and .22 caliber rimfire handgun and rifle cartridges, a few small-bore/gauge shotgun shells (intended mainly for use in pest control), and a handful of antiquated rimfire and pinfire cartridges for various firearm actions.

Cylinder (firearms)
In firearms, the cylinder is the cylindrical, rotating part of a revolver containing multiple chamber (firearms), chambers, each of which is capable of holding a single cartridge (firearms), cartridge. The cylinder rotates (revolves) around a central axis in the revolver's action (firearms), action to sequentially align each individual chamber with the gun barrel#Bore, barrel bore for repeated firing. Each time the gun is cocked, the cylinder indexing (motion), indexes by one chamber (for five-chambers, by 72Degree (angle), °, for six-chambers, by 60Degree (angle), °, for seven-chambers, by 51.43Degree (angle), °, for eight-chambers, by 45Degree (angle), °, for nine-chambers, by 40Degree (angle), °, and for ten-chambers, by 36Degree (angle), °). Serving the same function as a rotary magazine, the cylinder stores ammunitions within the revolver and allows it to repeating firearm, fire multiple times, before needing to be reloaded. Typically revolver cylinders are designed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (firearms)
A cartridge, also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance ( smokeless powder, black powder substitute, or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often used to refer to a complete cartridge, the correct usage only refers to the projectile. Military and commercial producers continue to pursue the goal of caseless ammunition. Some artillery ammunition uses the same cartridge concept as found in small arms. In other cases, the artillery shell is separate from the propellant charge. A cartridge without a projectile is called a '' blank''; one that is completely inert (contains no active primer and no propellant) is called a '' dummy''; one that ...

Stainless Steel
Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Stainless steel's resistance to corrosion comes from its chromium content of 11% or more, which forms a Passivation (chemistry), passive film that protects the material and can self-healing material, self-heal when exposed to oxygen. It can be further alloyed with elements like molybdenum, carbon, nickel and nitrogen to enhance specific properties for various applications. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for ch ...

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 specified maximum for any of the following elements does not exceed: manganese 1.65%; silicon 0.60%; and copper 0.60%. As the carbon content percentage rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point. The term may be used to reference steel that is not stainless steel; in this use carbon steel may include alloy st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluing (steel)
Bluing, sometimes spelled as blueing, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receiver (firearms)
In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing (engineering), housing for internal action (firearms), action components such as the hammer (firearms), hammer, bolt (firearms), bolt or breechblock, firing pin and extractor (firearms), extractor, and has screw thread, threaded interfaces for externally attaching ("receiving") components such as the gun barrel, barrel, stock (firearms), stock, trigger (firearms), trigger mechanism and iron sights, iron/sight (device)#Optical sights, optical sights. Some firearm designs, such as the AR-15 platform, feature receivers that have 2 separate sub-assemblies called the upper receiver which houses the barrel/trunnion, bolt components etc and the lower receiver (Trigger Mechanism Housing in some cases) that holds the fire control group, pistol grip, selector, stock etc. The receiver is often made of forged, machined, or stamped steel or aluminium.

Ruger GP100
The GP100 is a family/line of double action five- ( .44 Special), six- ( .357 Magnum, .38 Special, & 10mm Auto), seven- (.357 Magnum and .327 Federal Magnum), or ten-shot ( .22 Long Rifle) revolvers made by Sturm, Ruger & Co., manufactured in the United States. History The GP100 was an evolution of an earlier Ruger double-action revolver, the Security Six. It was introduced in 1985 as a second generation of the Ruger double-action, exposed-hammer revolvers intended to replace Ruger's Security-/Service-/Speed-Six line. It was made stronger with the intent to fire an unlimited number of full-power .357 Magnum rounds. The first significant change was introduced with the Ruger Redhawk and that involved a new triple-locking cylinder mechanism with a lever on the crane rather than using the end of the ejector rod to lock. Another change was the use of stronger steels and the redesigned, beefier shape of the frame. Traditional revolver frames had exposed metal at the front ...

United States Border Patrol
The United States Border Patrol (USBP) is a Federal law enforcement in the United States, federal law enforcement agency under the U.S. Customs and Border Protection, United States Customs and Border Protection (CBP) and is responsible for securing the borders of the United States. According to its website as of 2022, its mission is to "Protect the American people, safeguard our borders, and enhance the nation’s economic prosperity." With 19,648 agents in 2019, the Border Patrol is one of the largest law enforcement agencies in the United States. For fiscal year 2017, Congress enacted a budget of $3,805,253,000 for the Border Patrol. History In the nineteenth century, United States borders were open and unrestricted; there was no systematic control or even recordkeeping of immigrants. The first legislation restricting immigration, after the Act Prohibiting Importation of Slaves of 1807, was the Chinese Exclusion Act of 1882. Mounted watchmen of the United States Department o ...
