A revolver is a repeating handgun that has a revolving cylinder containing multiple chambers and at least one barrel for firing. The revolver allows the user to fire multiple rounds without reloading after every shot, unlike older single shot firearms. After a round is fired the hammer is cocked and the next chamber in the cylinder is aligned with the barrel by the shooter either manually pulling the hammer back or by rearward movement of the trigger. Revolvers still remain popular as back-up and off-duty handguns among American law enforcement officers and security guards and are still common in the American private sector as defensive and sporting/hunting firearms. Famous and iconic revolvers models include the Colt 1851 Navy Revolver, the Webley, the Colt Single Action Army, the Colt Official Police, Smith & Wesson Model 10, the Smith and Wesson Model 29 of Dirty Harry fame, the Nagant M1895. Though revolvers are referred to as and are handguns, other firearms may have a revolver action.
These include some models of grenade launchers, shotguns and cannons, such as revolver cannon. These are different from other firearms with revolving chambers, such as Gatling-style rotary cannons in that revolvers require the hammer to be re-cocked with each shot and require manual reloading, while guns like the minigun are motor driven and have a barrel for each chamber. In the development of firearms, an important limiting factor was the time it took to reload the weapon after it was fired. While the user was reloading, the weapon was useless, an adversary might be able to take advantage of the situation and kill or wound the user. Several approaches to the problem of increasing the rate of fire were developed, the earliest being multi-barrelled weapons which allowed two or more shots without reloading. Weapons featured multiple barrels revolving along a single axis. During the late 16th century in China, Zhao Shi-zhen invented the Xun Lei Chong, a five-barreled musket revolver spear. Around the same time, the earliest examples of what today is called a revolver were made in Germany.
These weapons featured a single barrel with a revolving cylinder holding the ball. They would soon be made in numerous designs and configurations. However, these weapons were difficult to use and prohibitively expensive to make, as such they were not distributed. In 1836, an American, Samuel Colt, patented the mechanism which led to the widespread use of the revolver, the mechanically indexing cylinder. According to Samuel Colt, he came up with the idea for the revolver while at sea, inspired by the capstan, which had a ratchet and pawl mechanism on it, a version of, used in his guns to rotate the cylinder by cocking the hammer; this provided a reliable and repeatable way to index each round and did away with the need to manually rotate the cylinder. Revolvers proliferated due to Colt's ability as a salesman, but his influence spread in other ways as well. Early revolvers were caplocks and loaded as a muzzle-loader: the user poured black powder into each chamber, rammed down a bullet on top of it placed percussion caps on the nipple at the rear of each chamber, where the hammer would fall on it.
This was similar to loading a traditional single-shot muzzle-loading pistol, except that the powder and shot could be loaded directly into the front of the cylinder rather than having to be loaded down the whole length of the barrel. This allowed the barrel itself to be rifled, since the user wasn't required to force the tight fitting bullet down the barrel in order to load it; when firing the next shot, the user would raise his pistol vertically as he cocked the hammer back so as to let the fragments of the burst percussion cap fall out so as to not jam the mechanism. Some of the most popular cap-and-ball revolvers were the Colt Model 1851 "Navy" Model, 1860 "Army" Model, Colt Pocket Percussion revolvers, all of which saw extensive use in the American Civil War. Although American revolvers were the most common, European arms makers were making numerous revolvers by that time as well, many of which found their way into the hands of the American forces, including the single action Lefaucheux and LeMat revolver and the Beaumont–Adams and Tranter revolvers, which were early double-action weapons, in spite of being muzzle-loaders.
In 1854, Eugene Lefaucheux introduced the Lefaucheux Model 1854, the first revolver to use self-contained metallic cartridges rather than loose powder, pistol ball, percussion caps. It is a pinfire revolver holding six rounds. On November 17, 1856, Daniel B. Wesson and Horace Smith signed an agreement for the exclusive use of the Rollin White Patent at a rate of 25 cents for every revolver. Smith & Wesson began production late in 1857 and enjoyed years of exclusive production of rear-loading cartridge revolvers in America, due to their association with Rollin White, who held the patent and vigorously defended it against any perceived infringement by other manufacturers. Although White held the patent, other manufacturers were able to sell firearms using the design, provided they were willing to pay royalties. After White's patent expired in April 1869, a 3rd extension was refused. Other gun-makers wer
The arms industry known as the defense industry or the arms trade, is a global industry which manufactures and sells weapons and military technology. It consists of a commercial industry involved in the research and development, engineering and servicing of military material and facilities. Arms-producing companies referred to as arms dealers, defence contractors, or as the military industry, produce arms for the armed forces of states and for civilians. Departments of government operate in the arms industry and selling weapons and other military items. An arsenal is a place where arms and ammunition - whether or publicly owned - are made and repaired, stored, or issued, in any combination. Products of the arms industry include guns, ammunition, military aircraft, military vehicles, electronic systems, night-vision devices, holographic weapon sights, laser rangefinders, laser sights, hand grenades and more; the arms industry provides other logistical and operational support. The Stockholm International Peace Research Institute estimated military expenditures as of 2012 at $1.8 trillion.
This represented a relative decline from 1990, when military expenditures made up 4% of world GDP. Part of the money goes to the procurement of military hardware and services from the military industry; the combined arms-sales of the top 100 largest arms-producing companies amounted to an estimated $395 billion in 2012 according to SIPRI. In 2004 over $30 billion were spent in the international arms-trade. According to SIPRI, the volume of international transfers of major weapons in 2010–14 was 16 per cent higher than in 2005–2009; the five biggest exporters in 2010–2014 were the United States, China and France, the five biggest importers were India, Saudi Arabia, the United Arab Emirates and Pakistan. Many industrialized countries have a domestic arms-industry to supply their own military forces; some countries have a substantial legal or illegal domestic trade in weapons for use by their own citizens for self-defence, hunting or sporting purposes. Illegal trade in small arms occurs in many regions affected by political instability.
The Small Arms Survey estimates that 875 million small arms circulate worldwide, produced by more than 1,000 companies from nearly 100 countries. Governments award contracts to supply their country's military; the link between politics and the arms trade can result in the development of what U. S. President Dwight D. Eisenhower described in 1961 as a military-industrial complex, where the armed forces and politics become linked to the European multilateral defence procurement. Various corporations, some publicly held, others private, bid for these contracts, which are worth many billions of dollars. Sometimes, as with the contract for the international Joint Strike Fighter, a competitive tendering process takes place, with the decision made on the merits of the designs submitted by the companies involved. Other times, no bidding or competition takes place. During the early modern period, United Kingdom and some states in Germany became self-sufficient in arms production, with diffusion and migration of skilled workers to more peripheral countries such as Portugal and Russia.
The modern arms industry emerged in the second half of the nineteenth century as a product of the creation and expansion of the first large military-industrial companies. As smaller countries could no longer produce cutting-edge military equipment with their indigenous resources and capacity, they began to contract the manufacture of military equipment, such as battleships, artillery pieces and rifles to foreign firms. In 1854, the British government awarded a contract to the Elswick Ordnance Company of industrialist William Armstrong for the supply of his latest breech loading rifled artillery pieces; this galvanised the private sector into weapons production, with the surplus being exported to foreign countries. Armstrong became one of the first international arms dealers, selling his weapon systems to governments across the world from Brazil to Japan. In 1884, he opened a shipyard at Elswick to specialise in warship production—at the time, it was the only factory in the world that could build a battleship and arm it completely.
The factory produced warships for many navies, including the Imperial Japanese Navy. Several Armstrong cruisers played an important role in defeating the Russian fleet at the Battle of Tsushima in 1905. In the American Civil War in 1861 the North had a distinct advantage over the south as it relied on using the breech-loading rifle against the muskets of the south; this began the transition to industrially produced mechanised weapons such as the Gatling gun. This industrial innovation in the defence industry was adopted by Prussia in 1866 & 1870-71 in its defeat of Austria and France respectively. By this time the machine gun had begun entering into the militaries; the first example of its effectiveness was in 1899 during the Boer War and in 1905 during the Russo-Japanese War. However, Germany were leaders in innovation of weapons and used this innovation nearly defeating the allies in World War I. In 1885, France decided to capitalize on this lucrative form of trade and repealed its ban on weapon exports.
The regulatory framework for the period up to the First World War was characterized by a laissez-faire policy that placed little obstruction in the way of weapons exports. Due to the carnage of World War I
A shotgun is a firearm, designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot, or a solid projectile called a slug. Shotguns come in a wide variety of sizes, ranging from 5.5 mm bore up to 5 cm bore, in a range of firearm operating mechanisms, including breech loading, single-barreled, double or combination gun, pump-action, bolt-, lever-action, semi-automatic, fully automatic variants. A shotgun was a smoothbore firearm, which means that the inside of the barrel is not rifled but rifled shotgun barrels and slugs become available. Preceding smoothbore firearms, such as the musket, were used by armies in the 18th century; the direct ancestor to the shotgun, the blunderbuss, was used in a similar variety of roles from self-defense to riot control. It was used by cavalry troops because of its shorter length and ease of use, as well as by coachmen for its substantial power. In the 19th century, these weapons were replaced on the battlefield with breechloading rifled firearms, which were more accurate over longer ranges.
The military value of shotguns was rediscovered in the First World War, when American forces used 12-gauge pump action shotguns in close-quarters trench fighting to great effect. Since it has been used in a variety of roles in civilian, law enforcement, military applications; the shot pellets from a shotgun spread upon leaving the barrel, the power of the burning charge is divided among the pellets, which means that the energy of any one ball of shot is low. In a hunting context, this makes shotguns useful for hunting birds and other small game. However, in a military or law enforcement context, the large number of projectiles makes the shotgun useful as a close quarters combat weapon or a defensive weapon. Militants or insurgents may use shotguns in asymmetric engagements, as shotguns are owned civilian weapons in many countries. Shotguns are used for target shooting sports such as skeet and sporting clays; these involve. Shotguns come in a wide variety of forms, from small up to massive punt guns, in nearly every type of firearm operating mechanism.
The common characteristics that make a shotgun unique center on the requirements of firing shot. These features are the features typical of a shotgun shell, namely a short, wide cartridge, with straight walls, operating at a low pressure. Ammunition for shotguns is referred to in the USA as shotshells, or just shells; the term cartridges is standard usage in the United Kingdom. The shot is fired from a smoothbore barrel; the typical use of a shotgun is against small and fast moving targets while in the air. The spreading of the shot allows the user to point the shotgun close to the target, rather than having to aim as in the case of a single projectile; the disadvantages of shot are limited range and limited penetration of the shot, why shotguns are used at short ranges, against smaller targets. Larger shot sizes, up to the extreme case of the single projectile slug load, result in increased penetration, but at the expense of fewer projectiles and lower probability of hitting the target. Aside from the most common use against small, fast moving targets, the shotgun has several advantages when used against still targets.
First, it has enormous stopping power at more than nearly all handguns and many rifles. Though many believe the shotgun is a great firearm for inexperienced shooters, the truth is, at close range, the spread of shot is not large at all, competency in aiming is still required. A typical self-defense load of buckshot contains 8–27 large lead pellets, resulting in many wound tracks in the target. Unlike a jacketed rifle bullet, each pellet of shot is less to penetrate walls and hit bystanders, it is favored by law enforcement for its low penetration and high stopping power. On the other hand, the hit potential of a defensive shotgun is overstated; the typical defensive shot is taken at close ranges, at which the shot charge expands no more than a few centimeters. This means. Balancing this is the fact that shot spreads further upon entering the target, the multiple wound channels of a defensive load are far more to produce a disabling wound than a rifle or handgun; some of the most common uses of shotguns are the sports of skeet shooting, trap shooting, sporting clays.
These involve shooting clay discs known as clay pigeons, thrown in by hand and by machine. Both skeet and trap competitions are featured at the Olympic Games; the shotgun is popular for bird hunting, it is used for more general forms of hunting in semi-populated areas where the range of rifle bullets may pose a hazard. Use of a smooth bore shotgun with a rifled slug or, alternatively, a rifled barrel shotgun with a sabot slug, improves accuracy to 100 m or more; this is well within the range of the majority of kill shots by experienced hunters using shotguns. However, given the low muzzle velocity of slug ammunition around 500 m/s, the blunt, poorly streamlined shape of typical slugs (which cause them to lose
U-boat is an anglicised version of the German word U-Boot, a shortening of Unterseeboot "underseaboat." While the German term refers to any submarine, the English one refers to military submarines operated by Germany in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most used in an economic warfare role and enforcing a naval blockade against enemy shipping; the primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, from the United States to the United Kingdom and to the Soviet Union and the Allied territories in the Mediterranean. German submarines destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on the Axis powers in 1944. Austro-Hungarian Navy submarines were known as U-boats; the first submarine built in Germany, the three-man Brandtaucher, sank to the bottom of Kiel harbor on 1 February 1851 during a test dive.
The inventor and engineer Wilhelm Bauer had designed this vessel in 1850, Schweffel & Howaldt constructed it in Kiel. Dredging operations in 1887 rediscovered Brandtaucher. There followed in 1890 the boats WW2, built to a Nordenfelt design. In 1903 the Friedrich Krupp Germaniawerft dockyard in Kiel completed the first functional German-built submarine, which Krupp sold to Russia during the Russo-Japanese War in April 1904; the SM U-1 was a redesigned Karp-class submarine and only one was built. The Imperial German Navy commissioned it on 14 December 1906, it had a double hull, a Körting kerosene engine, a single torpedo tube. The 50%-larger SM U-2 had two torpedo tubes; the U-19 class of 1912–13 saw the first diesel engine installed in a German navy boat. At the start of World War I in 1914, Germany had 48 submarines of 13 classes in service or under construction. During that war the Imperial German Navy used SM U-1 for training. Retired in 1919, it remains on display at the Deutsches Museum in Munich.
On 5 September 1914, HMS Pathfinder was sunk by SM U-21, the first ship to have been sunk by a submarine using a self-propelled torpedo. On 22 September, U-9 under the command of Otto Weddigen sank the obsolete British warships HMS Aboukir, HMS Cressy and HMS Hogue in a single hour. In the Gallipoli Campaign in early 1915 in the eastern Mediterranean, German U-boats, notably the U-21, prevented close support of allied troops by 18 pre-Dreadnought battleships by sinking two of them. For the first few months of the war, U-boat anticommerce actions observed the "prize rules" of the time, which governed the treatment of enemy civilian ships and their occupants. On 20 October 1914, SM U-17 sank the SS Glitra, off Norway. Surface commerce raiders were proving to be ineffective, on 4 February 1915, the Kaiser assented to the declaration of a war zone in the waters around the British Isles; this was cited as a retaliation for British minefields and shipping blockades. Under the instructions given to U-boat captains, they could sink merchant ships potentially neutral ones, without warning.
In February 1915, a submarine U-6 was rammed and both periscopes were destroyed off Beachy Head by the collier SS Thordis commanded by Captain John Bell RNR after firing a torpedo. On 7 May 1915, SM U-20 sank the liner RMS Lusitania; the sinking claimed 1,198 lives, 128 of them American civilians, the attack of this unarmed civilian ship shocked the Allies. According to the ship's manifest, Lusitania was carrying military cargo, though none of this information was relayed to the citizens of Britain and the United States who thought that the ship contained no ammunition or military weaponry whatsoever and it was an act of brutal murder. Munitions that it carried were thousands of crates full of ammunition for rifles, 3-inch artillery shells, various other standard ammunition used by infantry; the sinking of the Lusitania was used as propaganda against the German Empire and caused greater support for the war effort. A widespread reaction in the U. S was not seen until the sinking of the ferry SS Sussex.
The sinking occurred in 1915 and the United States entered the war in 1917. The initial U. S. response was to threaten to sever diplomatic ties, which persuaded the Germans to issue the Sussex pledge that reimposed restrictions on U-boat activity. The U. S. reiterated its objections to German submarine warfare whenever U. S. civilians died as a result of German attacks, which prompted the Germans to reapply prize rules. This, removed the effectiveness of the U-boat fleet, the Germans sought a decisive surface action, a strategy that culminated in the Battle of Jutland. Although the Germans claimed victory at Jutland, the British Grand Fleet remained in control at sea, it was necessary to return to effective anticommerce warfare by U-boats. Vice-Admiral Reinhard Scheer, Commander in Chief of the High Seas Fleet, pressed for all-out U-boat war, convinced that a high rate of shipping losses would force Britain to seek an early peace before the United States could react effectively; the renewed German campaign was effective, sinking 1.4 million tons of shipping between October 1916 and January 1917.
Despite this, the political situation demanded greater pressure, on 31 January 1917, Germany announced that its U-boats would engage in unrestricted submarine warfare beginning 1 February. On 17 March, German submarines sank three American merchant vessels, the U. S. declared wa
In the history of Europe, the Middle Ages lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery; the Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, the modern period. The medieval period is itself subdivided into the Early and Late Middle Ages. Population decline, counterurbanisation, collapse of centralized authority and mass migrations of tribes, which had begun in Late Antiquity, continued in the Early Middle Ages; the large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire—came under the rule of the Umayyad Caliphate, an Islamic empire, after conquest by Muhammad's successors. Although there were substantial changes in society and political structures, the break with classical antiquity was not complete.
The still-sizeable Byzantine Empire, Rome's direct continuation, survived in the Eastern Mediterranean and remained a major power. The empire's law code, the Corpus Juris Civilis or "Code of Justinian", was rediscovered in Northern Italy in 1070 and became admired in the Middle Ages. In the West, most kingdoms incorporated the few extant Roman institutions. Monasteries were founded; the Franks, under the Carolingian dynasty established the Carolingian Empire during the 8th and early 9th century. It covered much of Western Europe but succumbed to the pressures of internal civil wars combined with external invasions: Vikings from the north, Magyars from the east, Saracens from the south. During the High Middle Ages, which began after 1000, the population of Europe increased as technological and agricultural innovations allowed trade to flourish and the Medieval Warm Period climate change allowed crop yields to increase. Manorialism, the organisation of peasants into villages that owed rent and labour services to the nobles, feudalism, the political structure whereby knights and lower-status nobles owed military service to their overlords in return for the right to rent from lands and manors, were two of the ways society was organised in the High Middle Ages.
The Crusades, first preached in 1095, were military attempts by Western European Christians to regain control of the Holy Land from Muslims. Kings became the heads of centralised nation-states, reducing crime and violence but making the ideal of a unified Christendom more distant. Intellectual life was marked by scholasticism, a philosophy that emphasised joining faith to reason, by the founding of universities; the theology of Thomas Aquinas, the paintings of Giotto, the poetry of Dante and Chaucer, the travels of Marco Polo, the Gothic architecture of cathedrals such as Chartres are among the outstanding achievements toward the end of this period and into the Late Middle Ages. The Late Middle Ages was marked by difficulties and calamities including famine and war, which diminished the population of Europe. Controversy and the Western Schism within the Catholic Church paralleled the interstate conflict, civil strife, peasant revolts that occurred in the kingdoms. Cultural and technological developments transformed European society, concluding the Late Middle Ages and beginning the early modern period.
The Middle Ages is one of the three major periods in the most enduring scheme for analysing European history: classical civilisation, or Antiquity. The "Middle Ages" first appears in Latin in 1469 as media tempestas or "middle season". In early usage, there were many variants, including medium aevum, or "middle age", first recorded in 1604, media saecula, or "middle ages", first recorded in 1625; the alternative term "medieval" derives from medium aevum. Medieval writers divided history into periods such as the "Six Ages" or the "Four Empires", considered their time to be the last before the end of the world; when referring to their own times, they spoke of them as being "modern". In the 1330s, the humanist and poet Petrarch referred to pre-Christian times as antiqua and to the Christian period as nova. Leonardo Bruni was the first historian to use tripartite periodisation in his History of the Florentine People, with a middle period "between the fall of the Roman Empire and the revival of city life sometime in late eleventh and twelfth centuries".
Tripartite periodisation became standard after the 17th-century German historian Christoph Cellarius divided history into three periods: ancient and modern. The most given starting point for the Middle Ages is around 500, with the date of 476 first used by Bruni. Starting dates are sometimes used in the outer parts of Europe. For Europe as a whole, 1500 is considered to be the end of the Middle Ages, but there is no universally agreed upon end date. Depending on the context, events such as the conquest of Constantinople by the Turks in 1453, Christopher Columbus's first voyage to the Americas in 1492, or the Protestant Reformation in 1517 are sometimes used. English historians use the Battle of Bosworth Field in 1485 to mark the end of the period. For Spain, dates used are the death of King Ferdinand II in 1516, the death of Queen Isabella I of Castile in 1504, or the conquest of Granada in 1492. Historians from Romance-speaking countries tend to divide the Middle Ages into two parts: an earlier "High" and late
The Beretta 92 is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. The model 92 was designed in 1972 and production of many variants in different calibers continues today; the United States military replaced the M1911A1.45 ACP pistol in 1985 with the Beretta 92FS, designated as the M9. The Beretta 92 pistol evolved from earlier Beretta designs, most notably the M1923 and M1951. From the M1923 comes the open slide design, while the alloy frame and locking block barrel from Walther P38, were first used in the M1951; the grip angle and the front sight integrated with the slide were common to earlier Beretta pistols. What were the Model 92's two most important advanced design features had first appeared on its immediate predecessor, the 1974.380 caliber Model 84. These improvements both involved the magazine. In addition, the magazine was a "double-stacked" design, a feature introduced in 1935 on the Browning Hi-Power. Carlo Beretta, Giuseppe Mazzetti and Vittorio Valle, all experienced firearms designers, contributed to the final design in 1975.
Production began in May 1976, ended in February 1983. 7,000 units were of the first "step slide" design and 45,000 were of the second "straight slide" type. In order to meet requirements of some law enforcement agencies, Beretta modified the Beretta 92 by adding a slide-mounted combined safety and decocking lever, replacing the frame mounted manual thumb safety; this resulted in the 92S, adopted by several Italian law enforcement and military units. The magazine release button is at the bottom of the grip; this model was produced from 1978 - 1982. The 92SB called 92S-1, was designed for the USAF trials, the model name adopted was the 92SB. Features added include a firing pin block, ambidextrous safety levers, 3-dot sights, relocated the magazine release catch from the bottom of the grip to the lower bottom of the trigger guard; the relocation of the magazine release button means preceding models cannot use magazines, unless they have notches in both areas. A compact version with a shortened barrel and slide and 13-round magazine capacity known as the 92SB Compact was manufactured from 1981 to 1991.
Beretta modified the model 92SB to create the 92SB-F by making the following changes: Design of all the parts to make them 100% interchangeable to simplify maintenance for large government organizations. Squared off the front of the trigger guard so that one could use finger support for easier aiming. Recurved the forward base of the grip to aid aiming. Hard chromed the bore to reduce wear. New surface coating on the slide called Bruniton, which provides better corrosion resistance than the previous plain blued finish; the French military adopted a modified version of the 92F with a decocking-only lever as the PAMAS G1. These pistols have tellurium in the slide, making the steel brittle and as such only have a service life of 6,000 rounds; the FS has an enlarged hammer pin. The main purpose is to stop the slide from flying off the frame to the rear; this was in response to reported defective slides during U. S. military testing. The Beretta 92's open slide design ensures smooth feeding and ejection of ammunition and allows easy clearing of obstructions.
The hard-chromed barrel bore protects it from corrosion. The falling locking block design provides good accuracy and operability with suppressors due to the in-line travel of the barrel; this is in contrast to the complex travel of Browning designed barrels. The magazine release button is reversible with simple field tools. Reversing the magazine release makes left-handed operation much easier, it has become popular to reduce handgun weight and cost as well as increase corrosion resistance by using polymers. Starting around the year 2000, Beretta began replacing some parts with polymer and polymer coated metal. Polymer parts include the recoil spring guide rod, magazine floor plate, magazine follower and the mainspring cap/lanyard loop. Polymer coated metal parts include the left side safety lever and magazine release button. To keep in line with the introduction of laws in some locations restricting magazines that hold more than 10 rounds, Beretta now manufactures magazines that hold fewer than the factory standard 15 rounds.
These magazines have heavier crimping to reduce the available space while still keeping the same external dimensions and ensuring that these magazines can be used on existing firearms. Beretta produces 15 round "Sand Resistant" magazines to resolve issues encountered with contractor made magazines, 17 round magazines included with the A1 models. Both magazines function in M9 model pistols. Italian magazine manufacturer Mec-Gar now produces magazines in blue and nickel finishes with an 18-round capacity, which fit flush in the magazine well on the 92 series. Mec-Gar produces an extended 20-round blued magazine that protrudes below the frame by 3⁄4 inch; these magazines provide users in unrestricted states with a larger capacity magazine. The Beretta 92 is available in many configurations and models: 90Two The 90two is a 9mm/.40 variant of the 92-series with a redesigned, thicker slide and frame to acc
"Battle rifle" is a post-World War II term for military service rifles that are fed ammunition via detachable magazines and fire a full-powered rifle cartridge. The term "battle rifle" was created out of a need to better differentiate the intermediate-power assault rifles from full-powered automatic rifles as both classes of firearms have a similar appearance and share many of the same features such as detachable magazines, pistol grips, etc; this term may describe older military full-powered semi-automatic rifles such as the M1 Garand, Gewehr 43, MAS-49, the SVT-40. Before the 1980s and 1990s, the term was not well defined and was used as a general description for all types of military rifles. Designated marksman rifle Sniper rifle List of firearms
