NP-18
The NP-18 is a Norinco copy of the Hungarian made pistol '' FEG P9R''. Like the FEG P9R, it combines the design and operation of the Browning Hi-Power with the trigger mechanism of the Smith & Wesson double action trigger. Design The Norinco NP-18 is a Chinese copy of the FEG P9R. The handgun uses the 9×19mm Parabellum round, which is common in this type of guns. It has a heavy duty forged (not cast) steel frame and slide, which makes it one of the most solid, robust self-loading pistols that are actually in the market, because, unlike cast steel, forged steel Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it ... is made with strength and toughness in mind. It has a chrome-lined barrel to extend the barrel life, make it easier to clean, and better protect it from corrosion and ...

Semi-automatic Pistol
A semi-automatic pistol is a type of repeating single-chamber handgun ( pistol) that automatically cycles its action to insert the subsequent cartridge into the chamber (self-loading), but requires manual actuation of the trigger to actually discharge the following shot. As a result, only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/ striker until the trigger has been released and reset. Additional terms sometimes used as synonyms for a semi-automatic pistol are self-loading pistol, autopistol, autoloading pistol, and automatic pistol (E.G.: Automatic Colt Pistol). A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt, which is usually housed inside the slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer/s ...

9×19mm Parabellum
The 9×19mm Parabellum (also known as 9mm Parabellum or 9mm Luger or simply 9mm) is a rimless, tapered firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, it is widely considered the most popular handgun and submachine gun cartridge due to its low cost and extensive availability. It is a standard cartridge for NATO forces as well as in many non-NATO countries. Since the cartridge was designed for the Luger semi-automatic pistol, it has been given the designation of 9mm Luger by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the Commission internationale permanente pour l'épreuve des armes à feu portatives (CIP). A 2007 US survey concluded that "about 60 percent of the firearms in use by police are 9mm arabellum and credited 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.Adler, Jerry, et al.

Recoil Operation
Recoil operation is an operating mechanism used to implement locked breech, autoloading firearms. Recoil operated firearms use the energy of recoil to cycle the action, as opposed to gas operation or blowback operation using the pressure of the propellant gas. The earliest mention of recoil used to assist the loading of firearms is sometimes claimed to be in 1663 when an Englishman called Palmer proposed to employ either it or gases tapped along a barrel to do so. However no one has been able to verify this claim in recent times, although there is another automatic gun that dates from the same year, but its type and method of operation are unknown. Recoil-operation, if it was invented in 1663, would then lay dormant until the 19th century, when a number of inventors started to patent designs featuring recoil operation; this was due to the fact that the integrated disposable cartridge (both bullet and propellant in one easily interchangeable unit) made these designs viable.

Magazine (firearm)
A magazine is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine. Magazines come in many shapes and sizes, from tubular magazines on lever-action and pump-action firearms that may tandemly hold several rounds, to detachable box and drum magazines for automatic rifles and light machine guns that may hold more than one hundred rounds. Various jurisdictions ban what they define as "high-capacity magazines". Nomenclature With the increased use of semi-autom ...

P9RC
The P9RC is a semi-automatic pistol designed by József Kameniczky and manufactured by the FÉGARMY Arms Factory of Hungary. It was selected as the new service pistol of the Hungarian military and police, replacing the PA-63 after 1996. History After the collapse of the Soviet Union in 1990, the Hungarian military sought to replace its FÉG PA-63 sidearms in the Soviet 9×18mm Makarov cartridge with a handgun in the more powerful 9×19mm Parabellum. Originally the Israeli Baby Eagle/Jericho 941 was used until a domestically produced weapon could be chosen. In 1996 the P9RC was selected as the new standard issue sidearm for both the Hungarian military and police forces. Design and features The P9RC is the slightly modified version of the P9R, a design based on the Browning Hi-Power and Smith & Wesson Model 59 The Smith & Wesson Model 59 is a double-action pistol produced from 1971 to 1982. It was developed by Smith & Wesson from the earlier Smith & Wesson Model 39 by adapting ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Browning Hi-Power
The Browning Hi-Power is a single-action, semi-automatic pistol available in the 9×19mm Parabellum and .40 S&W calibers. It was based on a design by American firearms inventor John Browning, and completed by Dieudonné Saive at FN Herstal. Browning died in 1926, several years before the design was finalized. FN Herstal initially named the design the "High Power", which alludes to the 13-round magazine capacity, almost twice that of other designs at the time, such as the Luger or Colt M1911. During World War II, Belgium was occupied by Nazi Germany and the FN factory was used by the Wehrmacht to build the pistols for their military, under the designation "9mm Pistole 640(b)". FN Herstal continued to build guns for the Allied forces by moving their production line to a John Inglis and Company plant in Canada, where the name was changed to "Hi Power". The name change was kept even after production returned to Belgium. The pistol is often referred to as an HP or BHP, and the te ...

Steel Casting
Steel casting is a specialized form of casting involving various types of steel cast to either final/net or near-net shape. Steel castings are used when iron castings cannot deliver enough strength or shock resistance.Oberg, p. 1332 Examples of items that are steel castings include: hydroelectric turbine wheels, forging presses, gears, railroad truck frames, valve bodies, pump casings, mining machinery, marine equipment, turbocharger turbines and engine cylinder blocks. Steel castings are categorized into two general groups: carbon steels and alloy steels. Steel castability Steel is more difficult to cast than iron. It has a higher melting point and greater shrinkage rate, which requires consideration during mold design. Risers should be given more capacity to draw from as the metal cools and shrinks. Attention should be paid to the thickness of mold cavities, as thinner areas will cool quicker than thicker areas, which can create internal stress points that can lead to ...

Forging
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by smiths for millennia; the traditional products were kitchenware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanisms and machines wherever a component requires high strength; such forgings usually require further processing (such as machining) to achieve a finished part. Today, forging is a major worldwide industry. History Forging is one of the oldest known me ... [...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]   |

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 ...
