5.45×18mm
5.45×18mm MPTs (7N7) is a Soviet pistol cartridge. It is chambered in the PSM pistol, OTs-23 Drotik machine pistol and OTs-26 pistol. History and design It was designed in the Soviet Union in the early 1970s by Antonina D. Denisova at the Precision Mechanical Engineering Central Research Institute (TsNIITochmash). The development was done in concert with that of the PSM. The cartridge is designed to use light spitzer-pointed jacketed bullets. Variants * 5.45×18mm 7N7 (''7Н7''): spitzer-pointed full metal jacket bullet with steel conical core. The bullet energy is stated to be up to 1.5 times that of .25 ACP in a similar sized cartridge. It is stated to be capable of penetrating 45 layers of Kevlar soft body armor at close distances. * 5.45×18mm PSO (''ПСО''): spitzer-pointed full metal jacket bullet with lead core.Патрон 5,45х18 мм // А.

PSM Pistol
The PSM (''Pistolet Samozaryadny Malogabaritny'', Russian for "compact self-loading pistol") was designed by the Tula Design Bureau in 1969 as a self-defense firearm for law enforcement and military officers of the USSR. The pistol entered production at the Izhevsk Mechanical Plant in 1973. The PSM is a blowback-operated handgun with a double-action trigger and slide-mounted manual safety without a slide stop. The grip panels are made from thin aluminum and new model with hard plastic. The weapon is made from steel. The PSM was designed around the newly developed 5.45×18mm cartridge, which was developed for the weapon by Precision Mechanical Engineering Central Research Institute. The cartridge is capable of penetrating 55 layers of kevlar at realistic engagement distances. This cartridge has a bottlenecked case and a spitzer-pointed jacketed bullet. The pistol was primarily intended for army high command staff. However, owing to its insignificant dimensions, especially smal ...

OTs-23 Drotik
The OTs-23 Drotik (''ОЦ-23 Дротик'', Russian for "dart") is a blow-back operated machine pistol developed and used in Russia. The gun is also known as SBZ (Russian: СБЗ) from the initials of its designers — I. Stechkin, A.V. Baltser (А.В. Бальцер), and A.V. Zinchenko (А.В. Зинченко) The weapon has a three-position select fire switch; safe, semi-automatic, and three-round burst. The pistol features an external indicator that allows the operator to quickly see how many cartridges remain in the magazine. It is designed as a special operations and personal defence weapon (PDW). It has compensator openings cut into the end of the barrel to vent gases and make the weapon more stable during automatic burst fire. The action is blowback complicated with a principle borrowed from Pedersen's hesitation locking: after passing 42 mm and ejecting the case the free-moving bolt locks with the barrel and uses its inertia to stop in the last 5 mm of recoil.

OTs-21 Malysh
The OTs-21 Malysh (russian: ОЦ-21 «Малыш», meaning "kid") is a 9 mm semi-automatic pistol designed by the KBP Instrument Design Bureau for special applications where concealment is a key priority. The Malysh operates on the simple blowback principle; it is a double action only design with the ammunition capacity limited to five 9×18mm Makarov rounds (can use only 57-N-181S cartridges) in a box magazine with a base extension for more comfortable holding and firing. It features an internal hammer and there are no protrusions to hinder rapid withdrawal from a pocket or holster. The pistol has no safety other than the need for a definite pressure on the trigger. There are also no sights other than a groove along the top of the slide, emphasizing the intention that the OTs-21 Malysh is limited to very short-range engagements.

Blank (cartridge)
A blank is a firearm cartridge that, when fired, does not shoot a projectile like a bullet or pellet, but generates a muzzle flash and an explosive sound ( muzzle report) like a normal gunshot would. Firearms may need to be modified to allow a blank to cycle the action, and the shooter experiences less recoil with a blank than with a live round. Blanks are often used in prop guns for shooting simulations that have no need for ballistic results, but still demand light and sound effects, such as in historical reenactments, special effects for theatre, movie and television productions, combat training, for signaling (see starting pistol), and cowboy mounted shooting. Specialised blank cartridges are also used for their propellant force in fields as varied as construction, shooting sports, and fishing and general recreation. While blanks are less dangerous than live ammunition, they are dangerous and can still cause fatal injuries. Beside the explosive gases, any objects in the cartri ...

Body Armor
Body armor, also known as body armour, personal armor or armour, or a suit or coat of armor, is protective clothing designed to absorb or deflect physical attacks. Historically used to protect military personnel, today it is also used by various types of police (riot police in particular), private security guards or bodyguards, and occasionally ordinary civilians. Today there are two main types: regular non-plated body armor for moderate to substantial protection, and hard-plate reinforced body armor for maximum protection, such as used by combat soldiers. History Many factors have affected the development of personal armor throughout human history. Significant factors in the development of armor include the economic and technological necessities of armor production. For instance full plate armor first appeared in Medieval Europe when water-powered trip hammers made the formation of plates faster and cheaper. At times the development of armor has run parallel to the develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

25 ACP
The .25 ACP (Automatic Colt Pistol) (6.35×16mmSR) is a semi-rimmed, straight-walled centerfire pistol cartridge introduced by John Browning in 1905 alongside the Fabrique Nationale M1905 pistol. Design The cartridge is of semi-rimmed design meaning that the rim protrudes slightly beyond the diameter of the base of the cartridge so the cartridge can headspace on the rim.*Wilson, R. K. ''Textbook of Automatic Pistols''. Plantersville, SC: Small Arms Technical Publishing Company, 1943. p. 258. . Though the .25 ACP was designed for semi-automatic pistols, various .25 ACP revolvers were produced in the early twentieth century by Belgian, French, and German gunmakers such as Adolph Frank and Decker. In the late twentieth century, Bowen Classic Arms produced a custom Smith & Wesson revolver in .25 ACP.Bowen, Hamilton. ''The Custom Revolver''. Privately printed, 2001. . Performance The use of the .25 ACP allows for a very compact lightweight gun, usually pocket pistols, but the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Full Metal Jacket Bullet
A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead) encased in an outer shell ("jacket") of harder metal, such as gilding metal, cupronickel, or, less commonly, a steel alloy. A bullet jacket usually allows higher muzzle velocities than bare lead without depositing significant amounts of metal in the bore. It also prevents damage to bores from hard steel or armor-piercing core materials. History The bullet was invented in 1882 by Swiss Colonel Eduard Rubin while he was working for the Swiss Federal Ammunition Factory and Research Center, which developed ammunition for the Swiss military. The use of full metal jacketing in military ammunition came about in part because of the need for improved feeding characteristics in small arms that used internal mechanical manipulation of the cartridge in order to chamber rounds as opposed to externally hand-reloading single-shot firearms. The harder metal used in bullet jackets was less pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spitzer (bullet)
The spitzer bullet (or spire point) is a pointed projectile that is primarily used in small-arms. The pointed nose shape, which was developed for military purposes in the late 19th and early 20th century, was a major design improvement compared to earlier rounder or flatter-tipped bullets because pointed nose shapes were less susceptible to external ballistic factors like drag. By adding a point, projectiles made for fully-powered and intermediate rifle cartridges, obtain a lower drag coefficient which makes them decelerate less rapidly. Lowering the drag coefficient leads to improved external ballistic behaviour. The development of spitzer bullets and long-range volley sights for service rifles changed military doctrines. Area targets at ranges up to could be subject to rifle fire. With improvements in machine guns at the turn of the 20th Century, the addition of clinometers meant that fixed machine gun squads could deliver plunging fire or indirect fire at more than . ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Machine Pistol
A machine pistol is an autoloading pistol capable of fully automatic fire. The term can also be used to describe a stockless handgun-style submachine gun. The term is a calque of ''Maschinenpistole'', the German word for submachine guns. Machine pistols were developed during World War I and originally issued to German artillery crews who needed a self-defense weapon that is lighter than a rifle but more powerful than a standard semi-automatic pistol. This concept would eventually lead to the development of the personal defense weapon or PDW. Today, machine pistols are considered special-purpose weapons with limited utility, with their original niche being filled with either the PDW, carbines, or simply more modern semi-automatic sidearms. Contributing to their already-fringe use, without a shoulder stock and training, machine pistols can be difficult to control for all but the best shooters. The Austrians introduced the world's first machine pistol, the ''Steyr Repetierpistole' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistol
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict laws and regulations governing their manufa ...
