CZ 52
The CZ 52 (also known by the Czechoslovak military designations vz. 52, for (vz. - ''vzor'' = model) "model of 1952", and CZ 482) is a semi-automatic pistol designed by two brothers, Jan and Jaroslav Kratochvíl, in the early 1950s for the Czechoslovak military. Around 200,000 vz. 52s were made by Česká Zbrojovka in Strakonice from 1952 to 1954. Before standardizing on the 7.62×25mm vz. 52, the Czechoslovak military used several domestic and foreign pistol models in three different calibers. After 30 years of military service, the vz. 52 was eventually replaced by the 9×18mm Makarov caliber vz. 82. The CZ 52 is technically known as the vz. 52; the Czech military designation. It's often referred to as the CZ 52 to differentiate it from the vz. 52 rifle, which entered the export market before the pistol. Description The CZ 52 pistol is a roller-locked short recoil–operated, detachable box magazine–fed, single-action, semi-automatic pistol chambered for the 7.62×25m ...

Czechoslovak Socialist Republic
The Czechoslovak Socialist Republic, (Czech language, Czech and Slovak language, Slovak: ''Československá socialistická republika'', ČSSR) known from 1948 to 1960 as the Czechoslovak Republic (''Československá republika)'', Fourth Czechoslovak Republic, or simply Czechoslovakia, was the Czechoslovakia, Czechoslovak state from 1948 until 1989, when the country was under Marxist-Leninist state, communist rule, and was regarded as a satellite state in the Soviet Union, Soviet sphere of interest. Following the 1948 Czechoslovak coup d'état, coup d'état of February 1948, when the Communist Party of Czechoslovakia seized power with the support of the Soviet Union, the country was declared a "people's democratic state" when the Ninth-of-May Constitution became effective. The traditional name (''Czechoslovak Republic''), along with several other state symbols, were changed on 11 July 1960 following the implementation of the 1960 Constitution of Czechoslovakia as a symbol of th ...

De-cock/safety
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 generally can 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 "safe" to "fire" or something similar). Sometimes these are called "passive" and "active" safeties (or "automatic" and "manual"), respectively. External safeties typical work by prevent the trigger pull or prevent the firing pin from detonating the cartridge or both. 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-autom ...

Single-action
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 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 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 "s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parkerized
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. It is one of the most common types of conversion coating. The process is also called phosphate coating, phosphatization, phosphatizing, or phosphating. It is also known by the trade name Parkerizing, especially when applied to firearms and other military equipment. A phosphate coating is usually obtained by applying to the steel part a dilute solution of phosphoric acid, possibly with soluble iron, zinc, and/or manganese salts. The solution may be applied by sponging, spraying, or immersion. Phosphate conversion coatings can also be used on aluminium, zinc, cadmium, silver and tin. History The phosphatizing of firearms was discovered around 1910, when it was found that the surface of steel if changed to a phosphate acquires si ...

Pound (mass)
The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly , and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol (when there might otherwise be a risk of confusion with the pound-force) is lbm (for most pound definitions), # ( chiefly in the U.S.), and or ̶ (specifically for the apothecaries' pound). The unit is descended from the Roman (hence the symbol ''lb'', descended from the scribal abbreviation, '). The English word ''pound'' comes from the Roman ('the weight measured in '), and is cognate with, among others, German , Dutch , and Swedish . These units are now designated as historical and are no longer in common usage, being replaced by the metric system. Usage of the un ...

Caliber
In guns, particularly firearms, but not #As a measurement of length, artillery, where a different definition may apply, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel Gauge (firearms), bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimetres, millimeters]ref name=barnes2016-p9> In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a US "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11.43mm). Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise spe ...

9×19mm Parabellum
The 9×19mm Parabellum (also known as 9mm Luger, 9mm NATO or simply 9mm) is a Rim (firearms)#Rimless, rimless, Centerfire ammunition, centerfire, tapered cartridge (firearms), 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, adequate stopping power and extensive availability. Since the cartridge was designed for the Luger pistol, Luger semi-automatic pistol, it has been given the designation of ''9mm Luger'' by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the (CIP). A 2007 US survey concluded that "about 60 percent of the firearms in use by police are 9mm [Parabellum]" and credited 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.Adler, Jerry, et al.

Short Recoil
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. History 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 lie 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 viab ...

Roller-locked
In firearms operating systems, the term roller locked refers to locking the bolt with rollers. Notable examples of firearms using this method are the Polish wz.37 semi-automatic rifle designed by Edward Stecke, MG 42 general-purpose machine gun, which copied the solution of engineer Stecke and the CZ 52 semi-automatic pistol. It was also applied in the experimental ''Gerät 03'' semi-automatic rifle and '' Gerät 06'' and EM-1 experimental assault rifles. The MG 42's lineage continued past World War II, forming the basis for the nearly identical MG1 (MG 42/59), chambered in 7.62×51mm NATO, which subsequently evolved into the MG1A3, and later the Bundeswehr's MG 3, Italian MG 42/59, and Austrian MG 74. It also spawned the Yugoslav unlicensed nearly identical Zastava M53. History The origin of the roller-locking is debated: even though the general principle of utilizing "ball bearing parts" under radial pressure "for preventing uncoupling of the coupling members" was known n ...

CZ 82
The Pistole vz. 82 is a compact semi-automatic pistol made for the Czechoslovakian military. "vz." is an abbreviation for "vzor", which translates to "model." A civilian export version is called the CZ 83. Overview Manufactured by the Czechoslovak firm Česká zbrojovka the vz. 82 replaced the 7.62×25mm Tokarev vz. 52 pistol in Czechoslovak military service in 1983. It is a compact, single/double-action, semi-automatic pistol with a conventional blowback action. This type of action allows the barrel to remain solidly fixed to the frame, resulting in improved accuracy over pistols with pivoting barrels (like the U.S. M1911 series). The low bore axis of the vz. 82 provides for less muzzle rise and quicker follow-up shots. For added convenience, both the frame-mounted thumb safety and the magazine release are ambidextrous. The vz. 82 was the first service pistol to feature both these features. The bore is chrome plated, which gives it three advantages: longer barrel life, ...

9×18mm Makarov
The 9×18mm Makarov (designated 9mm Makarov by the C.I.P. and often called 9×18mm PM) is a pistol and submachine gun cartridge developed in the former USSR. During the latter half of the 20th century, it was a standard military pistol cartridge of the Soviet Union and the Eastern Bloc, analogous to the 9×19mm Parabellum in NATO and Western Bloc military use. History During the Second World War and the early Cold War, the 7.62×25mm Tokarev was the standard automatic pistol round for the Soviet Union and its satellites in Eastern Europe. This ammunition is still in use by many of these countries today. During the war, the Red Army had found a few shortcomings in its 7.62 mm TT-33 pistol, one of which was a tendency to inadvertently drop its magazine while in operation. The army wanted something that was lighter, with a heel release instead of a button and different ammunition. A direct blowback design was chosen for the pistol's operation, since it would be quick and cheap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
