Beretta M 1951
The Beretta M1951 is a 9×19mm semi-automatic pistol developed during the late 1940s and early 1950s by Pietro Beretta S.p.A. of Italy. The pistol was produced strictly for military use and was introduced into service with the Italian Armed Forces and other Italian security forces as the Modello 1951 (M1951), replacing the Modello 1934 pistol chambered for the 9×17mm Short (.380 ACP) cartridge. History The Beretta M1951 was Beretta's first locked-breech design on the market. (Previous Beretta semi-automatic pistols were all blowback-operated.) It was in limited production circa 1953 and in full-scale production from 1956 to 1980. The initial production batch featured a lightweight alloy frame, which proved to be unable to withstand the shock of the relatively high-powered 9×19mm Parabellum round in the long run. This version of the Beretta M1951 was replaced around 1955 by the steel-framed "second series" model. (Although in 1975 and 1976, a small number of alloy-framed B ...

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 ...

Polizia Stradale
The Polizia Stradale is the national highway patrol of Italy and is a sub-directorate of the Italian State Police. The ''Polizia Stradale'' patrols the 7,000 kilometers of motorways (''autostrada'') in Italy and the main highways and arterial roads outside towns. Missions include the prevention and detection of driving offences, traffic accident reporting, planning and carrying out services to regulate traffic, providing escorts for road safety, protecting and controlling the road network, rescue operations and cooperation in the collection of traffic flow data. Between the several activities it carries out also services of supply and regulation of the traffic. Under the profile of the communication verification the news on the practicability that then comes diffuse from the ''Center coordination information on street emergency'' (Centro Addestramento Polizia di Stato) (C.C.I.S.S.). It also promotes the initiatives and campaigns of sensibilities of the citizens, in particular you ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polizia Di Stato
The ''Polizia di Stato'' (State Police or P.S.) is one of the national police forces of Italy. Alongside the Carabinieri, it is the main police force for providing police duties, primarily to cities and large towns, and with its child agencies it is also responsible for highway patrol (''autostrade''), railways (''ferrovie''), airports (''aeroporti''), customs (together with the ''Guardia di Finanza'') as well as certain waterways, and assisting the local police forces. It was a military force until 1981 when the Italian State Law 121 was passed. This converted the State Police to a civil force, which is in contrast to the other main police forces of Italy: the '' Arma dei Carabinieri'', which is a military police (gendarmerie) force and the ''Guardia di Finanza'', the Italian customs and border protection police that also falls in the military corps category. The ''Polizia di Stato'' is the principal Italian police force for the maintenance of public security and as such it i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian Special Forces
The Italian Special Forces include special forces units from several branches of the Italian Armed Forces: the ''Esercito Italiano'' (Army), the ''Marina Militare'' (Navy), the ''Aeronautica Militare'' (Air force) and the ''Arma dei Carabinieri'' (Gendarmerie). Italian Armed Forces special units are divided into Special Forces (TIER 1) and Special Operations Forces (TIER 2), and the ''Comando operativo interforze delle forze speciali'' (Joint Special Forces Operations Headquarters) is responsible for the operations carried out in response to Defense requirements. Italian Army special units Tier 1 * 9th Paratroopers Assault Regiment "Col Moschin", is a SAS-like force trained for special operations in various environments. They carry the legacy of the ''Arditi'' units of the Italian Army, which operated on the Italian-Austrian Front during World War I. Tier 2 * 4th Alpini Paratroopers Regiment, is a Ranger type infantry alpini regiment, specializing in mountain combat, and ...

Select Fire
Selective fire is the capability of a weapon to be adjusted to fire in semi-automatic, fully automatic, and/or burst mode. The modes are chosen by means of a selector switch, which varies depending on the weapon's design. Some selective-fire weapons have burst fire mechanisms to limit the maximum number of shots fired automatically in this mode. The most common limits are two or three rounds per trigger pull. Fully automatic fire refers to the ability for a weapon to fire continuously until either the feeding mechanism is emptied or the trigger is released. Semi-automatic refers to the ability to fire one round per trigger pull. The presence of selective fire modes on firearms permits more efficient use of rounds to be fired for specific needs, versus having a single mode of operation, such as fully automatic, thereby conserving ammunition while maximizing on-target accuracy and effectiveness. This capability is most commonly found on military weapons of the 20th and 21st centu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – barrel ...

Magazine (firearms)
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-au ... [...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] |
Walther P38
The Walther P38 (originally written Walther P.38) is a 9 mm semi-automatic pistol that was developed by Carl Walther GmbH as the service pistol of the Wehrmacht at the beginning of World War II. It was intended to replace the costly Luger P08, the production of which was scheduled to end in 1942. Development The first designs was submitted to the German Army and featured a locked breech and a hidden hammer, but the Army requested that it should be redesigned with an external hammer. The P38 concept was accepted by the German military in 1938 but production of prototype ("Test") pistols did not begin until late 1939. Walther began manufacture at their plant in Zella-Mehlis and produced three series of "Test" pistols, designated by a "0" prefix to the serial number. The third series pistols satisfactorily solved the previous problems for the German Army and mass production began in mid-1940, using Walther's military production identification code "480". Several experimental ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
