Ruger GP100
The GP100 is a family/line of double action five-shot (.44 Special), six-shot (.357 Magnum, .38 Special, & 10mm Auto), seven-shot (.357 Magnum & .327 Federal Magnum), or ten-shot (.22 Long Rifle) revolvers made by Sturm, Ruger & Co., manufactured in the United States. Since its introduction, it has been produced with a number of variations including various barrel lengths and profiles, fixed or adjustable sights, and in blued carbon steel or stainless steel. Description and features 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 locking mechanism with a lever on the crane rather than usin ...

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-shot fir ...

Ruger Security-Six
The Ruger Security-Six and its variants, the Service-Six and Speed-Six are a product line of double-action revolvers introduced in 1972 and manufactured until 1988 by Sturm, Ruger & Company. These revolvers were marketed to law enforcement 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, Bill Ruger wanted to get into law enforcement and security contracts. Smith & Wesson and Colt at the time dominated the medium frame law enforcement double action revolver contracts. The introduction of the Security-Six and its variants marked Sturm Ruger's first attempt to enter the double-action revolver market. The corporation's earlier designs had been Colt Peacemaker-style single-action revolvers. Ruger used investment casting for most parts in an effort to hold down production costs.Tong, David†...

Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder 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 the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a ...

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 user ...

Safety (firearms)
Close-up shot of a safety of an M16A2 rifle In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties can generally be divided into subtypes such as internal safeties (which typically do not receive input from the user) and external safeties (which typically allow the user to give input, for example, toggling a lever from "on" to "off" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively. Firearms with the ability to allow the user to select various fire modes may have separate switches for safety and for mode selection (e.g. Thompson submachine gun) or may have the safety integrated with the mode selector as a fire selector with positions from safe to semi-automatic to full-automatic fire (e.g. M16). Some firearms manufactured after the late 1990s and early 2000s include a mandatory integral locking mecha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firing Pin
A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer. The terms may also be used for a component of equipment or a device which has a similar function. Such equipment or devices include: artillery, munitions and pyrotechnics. Firearms The typical firing pin is a thin, simple rod with a hardened, rounded tip that strikes and crushes the primer. The rounded end ensures the primer is indented rather than pierced (to contain propellant gasses). It sits within a hole through the breechblock and is struck by the hammer when the trigger is "pulled". A light firing-pin spring is often used to keep the firing pin rearward. It may be termed a ''firing-pin return spring'', since it returns it to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Barrel
A gun barrel is a crucial part of gun-type weapons such as small firearms, artillery pieces, and air guns. It is the straight shooting tube, usually made of rigid high-strength metal, through which a contained rapid expansion of high-pressure gas(es) is used to propel a projectile out of the front end ( muzzle) at a high velocity. The hollow interior of the barrel is called the bore, and the diameter of the bore is called its caliber, usually measured in inches or millimetres. The first firearms were made at a time when metallurgy was not advanced enough to cast tubes capable of withstanding the explosive forces of early cannons, so the pipe (often built from staves of metal) needed to be braced periodically along its length for structural reinforcement, producing an appearance somewhat reminiscent of storage barrels being stacked together, hence the English name.''A History of Warfare'' - Keegan, John, Vintage 1993. History Gun barrels are usually metal. However, the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruger SP101
The Ruger SP101 is a series of double-action revolvers produced by the American company Sturm, Ruger & Co. The SP101 is a small frame and all-steel-construction carry revolver, with a five-shot (.38 Special, .357 Magnum, and 9×19mm Parabellum), six-shot (.327 Federal Magnum and .32 H&R Magnum), or eight-shot (.22 LR) cylinder. History The Ruger SP101 was introduced in 1989 as the smaller-frame counterpart to the GP100. Both of these revolvers, together, replaced Sturm, Ruger & Co's long-standing staple in the American firearms market, the Ruger Security-Six series revolvers. A 9 mm version was available until its discontinuation around 1998, but was later re-released in early 2018. A basic .22 LR version was also available until 2003 while a redesigned version was introduced in 2011. Features and description *The SP101 is currently manufactured in .327 Federal Magnum, .357 Magnum, 9 mm, .38 Special, and .22 LR. *Barrel lengths 2" (57.15mm), 3" (77.79mm), and 4" (106.7mm) w ...

Rosewood
Rosewood refers to any of a number of richly hued timbers, often brownish with darker veining, but found in many different hues. True rosewoods All genuine rosewoods belong to the genus ''Dalbergia''. The pre-eminent rosewood appreciated in the Western world is the wood of ''Dalbergia nigra''. It is best known as "Brazilian rosewood", but also as "Bahia rosewood". This wood has a strong, sweet smell, which persists for many years, explaining the name ''rosewood''. Another classic rosewood comes from ''Dalbergia latifolia'', known as (East) Indian rosewood or ''sonokeling'' (Indonesia). It is native to India and is also grown in plantations elsewhere in Pakistan (Chiniot). Madagascar rosewood (''Dalbergia maritima''), known as ''bois de rose'', is highly prized for its red color. It is overexploited in the wild, despite a 2010 moratorium on trade and illegal logging, which continues on a large scale. Throughout southeast Asia, ''Dalbergia oliveri'' is harvested for use in ...

Goncalo Alves
Gonçalo alves is a hardwood (from the Portuguese name, Gonçalo Alves). It is sometimes referred to as tigerwood—a name that underscores the wood's often dramatic, contrasting color scheme, that some compare to rosewood. While the sapwood is very light in color, the heartwood is a sombre brown, with dark streaks that give it a unique look. The wood's color deepens with exposure and age and even the plainer-looking wood has a natural luster. Two species are usually listed as sources for gonçalo alves: ''Astronium fraxinifolium'' and ''Astronium graveolens'', although other species in the genus may yield similar wood; the amount of striping that is present may vary. All trees grow in neotropical The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone. Definition In bioge ... forests; Brazil is a major exporter ...

Elastomer
An elastomer is a polymer with viscoelasticity (i.e. both viscosity and elasticity) and with weak intermolecular forces, generally low Young's modulus and high failure strain compared with other materials. The term, a portmanteau of ''elastic polymer'', is often used interchangeably with rubber, although the latter is preferred when referring to vulcanisates. Each of the monomers which link to form the polymer is usually a compound of several elements among carbon, hydrogen, oxygen and silicon. Elastomers are amorphous polymers maintained above their glass transition temperature, so that considerable molecular reconformation is feasible without breaking of covalent bonds. At ambient temperatures, such rubbers are thus relatively compliant ( E ≈ 3 M Pa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts. Application areas for different types of rubber are manifold and cover segments as diverse as tires, soles for shoes, and damping and ...
