MSP Groza Silent Pistol
The MSP Groza ("thunderstorm") silent pistol is an over and under, double-barrel, derringer-type firearm designed in the Soviet Union in 1972. The firearm is chambered for the silent 7.62×38 SP-3 cartridge which can be loaded via a two-round clip. The weapon was designed at the request of the Soviet special services. It is no longer in production, having been superseded by more modern designs. The weapon was used operationally in Afghanistan and in Central America during the Cold War. An FMLN supplied MSP is believed to have been the weapon used to assassinate Contras leader Enrique Bermúdez Design The Groza uses a specialised cartridge. When fired, an internal piston within the cartridge launches the bullet forward and retains all the gases within the case, thus making a near silent weapon with almost no flash. To load the weapon the user would depress a button, allowing the barrels to tilt forward and exposing the breech for manual loading either by individual cartridge or w ...

Suppressor (firearms)
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a muzzle device that reduces the acoustic intensity of the muzzle report (sound of a gunshot) and muzzle rise when a gun (firearm or air gun) is discharged, by modulating the speed and pressure of the propellant gas from the muzzle and hence suppressing the muzzle blast. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle, or an integral part of the barrel. A typical silencer is a metallic (usually stainless steel or titanium) cylinder containing internal sound baffles, with a hollow bore to allow the projectile (bullet) to exit normally. During firing, the bullet flies through the bore with little hindrance, but most of the expanding gas ejecta behind it is retained through a longer and convoluted escape path created by the baffles, prolonging the release time. This slows down the gas and dissipates its kinetic energy into a larger surface area, reduci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derringer
A derringer is a small handgun that is neither a revolver nor a semi/ fully automatic pistol. It is not to be confused with mini-revolvers or pocket pistols, although some later derringers were manufactured with the pepperbox configuration. The modern derringer is often multi-barreled, and is generally the smallest usable handgun of any given caliber and barrel length due to the lack of a moving action, which takes up more space behind the barrel. It is frequently used by women because it is easily concealable in a purse or a stocking. The original Philadelphia Deringer was a muzzleloading caplock single-shot pistol introduced in 1825 by Henry Deringer. In total, approximately 15,000 Deringer pistols were manufactured. All were single barrel pistols with back-action percussion locks, typically .41 caliber with rifled bores, and walnut stocks. Barrel length varied from , and the hardware was commonly a copper-nickel alloy known as "German silver". The term "derringer ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet–Afghan War
The Soviet–Afghan War was a protracted armed conflict fought in the Democratic Republic of Afghanistan from 1979 to 1989. It saw extensive fighting between the Soviet Union and the Afghan mujahideen (alongside smaller groups of anti-Soviet Maoism, Maoists) after the former militarily intervened in, or launched an invasion of, Afghanistan to support the local pro-Soviet government that had been installed during Operation Storm-333. Most combat operations against the mujahideen took place in the Afghan countryside, as the country's urbanized areas were entirely under Soviet control. While the mujahideen were backed by various countries and organizations, the majority of their support came from Pakistan, Saudi Arabia, the United States, the United Kingdom, China, and Iran; the American pro-mujahideen stance coincided with a sharp increase in bilateral hostilities with the Soviets during the Cold War (1979–1985), Cold War. The conflict led to the deaths of between 562,000 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tula Arsenal
Imperial Tula Arms Plant (russian: Императорский Тульский оружейный завод, Imperatorskiy Tulsky Oruzheiny Zavod) is a Russian weapons manufacturer founded by Tsar Peter I of Russia in 1712 in Tula, Tula Oblast as Tula Arsenal.

Break-action
Break action is a type of firearm action in which the barrel or barrels are hinged much like a door and rotate perpendicularly to the bore axis to expose the breech and allow loading and unloading of cartridges. A separate operation may be required for the cocking of a hammer to fire the new round. There are many types of break-action firearms; break actions are universal in double-barrelled shotguns, double-barrelled rifles, combination guns, and are also common in single shot pistols (especially derringers), rifles, shotguns, and can also be found in flare guns, grenade launchers, air guns, and some older revolver designs. They are also known as hinge-action, break-open, break-barrel, break-top, or, on old revolvers, top-break actions. Description Break action The first break-action revolver was patented in France and Britain at the end of December in 1858 by Devisme. A substantial hinge pin joins the two parts of the rifle or shotgun; the stock with its firing mechanism and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigger (firearms)
A trigger is a mechanism that actuates the function of a ranged weapon such as a firearm, airgun, crossbow, or speargun. The word may also be used to describe a switch that initiates the operation of other non-shooting devices such as a trap, a power tool or a quick release. A small amount of energy applied to the trigger leads to the release of much more energy. Most triggers use a small flattened lever (called the ''trigger blade'') depressed by the index finger, but some weapons such as the M2 Browning machine gun or the Iron Horse TOR ("thumb-operated receiver") use a push-button-like thumb-actuated trigger design, and others like the Springfield Armory M6 Scout use a squeeze-bar trigger similar to the "ticklers" on medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer specifically to the trigger blade. Most firearm triggers are "single-action", meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Clip (ammunition)
A clip is a device that is used to store multiple rounds of ammunition together as a unit for insertion into the magazine or cylinder of a firearm. This speeds up the process by loading the firearm with several rounds at once, rather than one at a time ('loose rounds'). There are several types, most made of inexpensive stamped sheet metal, intended to be disposable, though they are often re-used. Types Stripper A stripper clip (US) or charger (UK) is a speedloader that holds several cartridges as a unit for easier loading into a firearm's internal magazine. After the bolt is opened and the stripper clip is placed in position (generally in a slot on the receiver or bolt), the cartridges are pressed down, removing or 'stripping' them off the clip and into the magazine. The clip is then either removed and tossed away, or the bolt is thrown forward, expelling the clip automatically. However, some weapons, such as the Mosin–Nagant require the operator to manually remove the emp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contras
The Contras were the various U.S.-backed and funded right-wing rebel groups that were active from 1979 to 1990 in opposition to the Marxist Sandinista Junta of National Reconstruction Government in Nicaragua, which came to power in 1979 following the Nicaraguan Revolution. Among the separate contra groups, the Nicaraguan Democratic Force (FDN) emerged as the largest by far. In 1987, virtually all Contra organizations were united, at least nominally, into the Nicaraguan Resistance. During their war against the Nicaraguan government, the Contras committed numerous human rights violations and used terrorist tactics. These actions were frequently carried out systematically as a part of the strategy of the Contras. Supporters of the Contras tried to downplay these violations, particularly the Reagan administration in the U.S., which engaged in a campaign of white propaganda to alter public opinion in favor of the Contras, while covertly encouraging the Contras to attack civilian ...

Enrique Bermúdez
Enrique Bermúdez Varela (December 11, 1932 – February 16, 1991), known as Comandante 380, was a Nicaraguan soldier and rebel who founded and commanded the Nicaraguan Contras. In this capacity, he became a central global figure in one of the most prominent conflicts of the Cold War. Bermúdez founded the largest Contra army in the war against Nicaragua's Marxist Sandinista government, which was supported by the Soviet Union and Cuba. From 1979 until the end of the military conflict in 1990, Bermudez was the Contras' top military commander. In addition to being responsible for all of the Contras' military operations, Bermúdez ultimately helped manage the Contras' transition to an opposition political party in the early 1990s after the second election in post-Somoza Nicaragua ended in defeat for the Sandinistas. The first election, held in 1984 with severe irregularities, resulted in a victory for the Daniel Ortega and the Sandinistas; it was the rejection of this questionable ...
