MSP Groza Silent Pistol
The MSP Groza silent pistol () is an over and under, double-barrel, derringer-type firearm designed in the Soviet Union in 1972. History 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. It is no longer in production, having been superseded by more modern designs. 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 with the use of a disposable 2-round clip. 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 ...

Suppressor (firearms)
A silencer, also known as a sound suppressor, suppressor, or sound moderator, is a gun barrel#Muzzle, muzzle device that suppresses the muzzle blast, blast created when a gun (firearm or airgun) is discharged, thereby reducing the sound intensity, acoustic intensity of the muzzle report (sound of a gunshot) and muzzle rise, jump, by modulating the speed and pressure of the propellant gas released from the muzzle. Like other muzzle devices, a silencer can be a detachable accessory mounted to the muzzle or an integral part of the gun barrel, barrel. A typical silencer is a metallic (usually stainless steel or titanium) cylinder (firearms), cylinder containing numerous internal sound baffles, with a hollow bore to allow the bullet to exit normally. During firing, the bullet passes through the bore with little hindrance, but most of the expanding gas ejecta behind it is redirected through a longer and convoluted escape path created by the baffles, prolonging the release time.

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern 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. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...

Pistols Of The Soviet Union
A pistol is a type of handgun, characterised by a barrel with an integral chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term 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. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the lack of a buttstock) and strict laws and regulations governing their manufacture and sa ...

PSS Silent Pistol
The PSS silent pistol or MSS "Vul" ("Вул") is a Soviet silent pistol operating on a sealed cartridge system. Operation Cartridge The PSS uses a specially developed 7.62×41 mm necked round SP-4 (СП-4), also used by the OTs-38 Stechkin silent revolver. The Cartridge (firearms), cartridge contains a propelling charge which drives an internal piston in contact with the base of the bullet. On firing, the piston propels the bullet out of the barrel with enough energy to achieve an effective range of 25 meters. At the end of its travel, the piston seals the cartridge neck, preventing noise, smoke, or blast from escaping. Action The PSS is recoil-operated. It has a slide designed to operate silently, in keeping with the pistol's design for silent operation. In other respects, the PSS generally follows traditional conventions, except for the slide's guide rod, which is located above the barrel and instead of guide rails on the pistol frame. The weapon uses a special ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Derringer
A derringer or deringer is a small handgun that is neither a revolver, semi-automatic pistol, nor machine 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (firearms), magazine or Cylinder (firearms), cylinder of a firearm. This speeds up the process by loading the firearm with multiple rounds simultaneously, rather than individually, as with loose rounds of ammunition. There are several types, most made of inexpensive Stamped metal, stamped sheet metal, generally they are intended to be disposable, but they are more often retained and reused. Types Stripper A stripper clip (American English) or charger clip (Commonwealth English) is a speedloader that holds several pistol or rifle cartridges as a unit for easier loading into a firearm's internal box 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 tos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 that fought against Nicaragua's Sandinista government; in the war, the Contras were supported by the US and the Sandinistas were 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 alleged severe irregularities, resulted in a victory for the Daniel Ortega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contras
In the history of Nicaragua, the Contras (Spanish: ''La contrarrevolución'', the counter-revolution) were the right-wing militias who waged anti-communist guerilla warfare (1979–1990) against the Marxist governments of the Sandinista National Liberation Front and the Junta of National Reconstruction, which came to power after the Nicaraguan Revolution in 1979. Months after the political dynasty (1936–1979) of the Somoza family lost the Nicaraguan Revolution to the Sandinistas, the US government sponsored the remaining national-guard soldiers and Somocista politicians of the losing side as ''la Contra'', the right-wing counter-revolution. The American military assistance and financial aid granted the Contras a measure of political credibility and military utility as anti-communist militias useful to U.S. foreign policy in Latin America. In 1986, consequent to complaints of the Contras' regular violation of the human rights of Nicaraguan civilians, the Boland Ame ...

Thunder
Thunder is the sound caused by lightning. Depending upon the distance from and nature of the lightning, it can range from a long, low rumble to a sudden, loud crack. The sudden increase in temperature and hence pressure caused by the lightning produces rapid Thermal expansion, expansion of the air in the path of a Lightning strike, lightning bolt. In turn, this expansion of air creates a Shock wave, sonic shock wave, often referred to as a "thunderclap" or "peal of thunder". The scientific study of thunder is known as ''brontology'' and the irrational fear (phobia) of thunder is called ''brontophobia''. Etymology The ''d'' in Modern English ''thunder'' (from earlier Old English ''þunor'') is epenthetic, and is now found as well in Modern Dutch ''donder'' (cf. Middle Dutch ''donre''; also Old Norse ''þorr'', Old Frisian ''þuner'', Old High German ''donar'', all ultimately descended from Proto-Germanic *''þunraz''). In Latin the term was ''tonare'' "to thunder". The name of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigger (firearms)
A trigger is a mechanism (engineering), mechanism that Actuator, 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 animal trap, 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 flat or slightly curved 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 crossbow#Medieval Europe, medieval European crossbows. Although the word "trigger" technically implies the entire mechanism (known as the ''trigger group''), colloquially it is usually used to refer ...
