P2000 SK
72-470: The Heckler & Koch P2000 is a German semi-automatic pistol introduced late in 2001 and intended primarily for law enforcement, paramilitary , and commercial markets. It is based on the USP Compact pistol. The P2000 was designed specifically with improved ergonomic characteristics; it has features that reduce handling related stresses, while at the same time increasing user handling and comfort. From
144-605: A prefix of between one and three letters, corresponding to a word or term in German (though some refer to English terms instead, with no German equivalent). Several were only used for a single model, such as the "Universal" weapons ( UMP , UCP , USC , USP ). Some abbreviations are used as a suffix to designate specific variants. Variant Version Submachine Gun Suppressor USP9 SD (for weapons with an extended threaded barrel intended for suppressors) The Werknummern designation system assigns two or three digits that correspond to
216-528: A PDA. It is unclear how extensively this option was exercised, but it was in the statement of work, so HK provided it. Other updates that were incorporated with the P2000 series included adding rubber base plates for the magazines. This helped dissipate energy during a magazine drop during reloads, thus extending the life of the magazines, as well as aiding in passing the Drop Test requirements described earlier. Within
288-588: A design licensed from Benelli, such as the Franchi Affinity. Then the Browning Arms Company introduced the inertia-operated A5 (trademarked as Kinematic Drive) as successor to the long-recoil operated Auto-5 . Both the Benelli and Browning systems are based on a rotating locking bolt, similar to that used in many gas-operated firearms. Before firing, the bolt body is separated from the locked bolt head by
360-406: A group of private investors, who created the German group holding company HK Beteiligungs GmbH. In 2003, HK Beteiligungs GmbH's business organization restructured as Heckler & Koch Jagd und Sportwaffen GmbH (HKJS), and its business was separated into the two business areas similar to the 1974 business mission areas: Defense, and Law Enforcement and Sporting Firearms. In 2004, Heckler & Koch
432-526: A majority stake in Heckler & Koch since July 2020. With the fall of Nazi Germany and the following Allied occupation of Germany , Oberndorf came under French control , and the entire Waffenfabrik Mauser AG factory was dismantled by French occupying forces. All factory records were destroyed on orders of the local French Army commander. In 1948, three former Mauser engineers, Edmund Heckler , Theodor Koch , and Alex Seidel , saved what they could from
504-514: A new idea at the time, rather than true recoil operation. The next to mention recoil operation in the British patent literature is by Alexander Blakely in 1862, who clearly describes using the recoil of a fired cannon to open the breech. In 1864 after the Second Schleswig War , Denmark started a program intended to develop a gun that used the recoil of a fired shot to reload the firearm, though
576-619: A proper abbreviation ("HK" does not mean anything specific), nor does it use proper digits (the HK416 was originally two models, the "HK M4 " and "HK M16 ", that were later amalgamated into the HK416); using the 3-digit system, the standard HK416 would likely be referred to as the G333. Such products tend to have proper internal designations anyway; the HK416 is internally referred to as the HK333. Most HK products have
648-483: A proprietary H&K mounting rail that limits the types of accessories that could be used with the pistol. The P2000 is a hammer-fired pistol with an exposed spurred hammer; a bobbed hammer is optional. It has an ambidextrous slide lock and a fully ambidextrous magazine release installed in the trigger guard. Various trigger and cocking systems offer the possibility of converting the trigger firing mode from one type to another. Several variants are available based whether
720-633: A result of efforts by civil society and human rights organizations in Mexico and Germany, H&K and two of its former employees were brought before the Provincial Court of Stuttgart. After ten months of trial, on 21 February 2019, the court convicted them of illegally selling arms to Mexican governmental institutions which failed to acknowledge their due observance of human rights. The two former employees (sales manager Sahlmann and administrative employee Beuter) had been found to have used fraudulent permits in
792-436: A spring that absorbs the recoil energy as it is compressed by the movement and then expands providing energy for the rest of the operating cycle. Since there is a minimum momentum required to operate a recoil-operated firearm's action, the cartridge must generate sufficient recoil to provide that momentum. Therefore, recoil-operated firearms work best with a cartridge that yields a momentum approximately equal to that for which
SECTION 10
#1732852696159864-469: A stiff spring. As the shotgun recoils after firing, inertia of the bolt body is large enough for it to remain stationary while the recoiling gun and locked bolt head move rearward. This movement compresses the spring between the bolt head and bolt body, storing the energy required to cycle the action. Since the spring can only be compressed a certain amount, this limits the amount of force the spring can absorb, and provides an inherent level of self-regulation to
936-666: A variety of firearms including the G3 , HK21 , MP5 , HK4 , HK33 , HK69 , VP70 , PSG1 , USP , G36 , MG4 , UMP , MP7 , and HK416 , which have become some of the most iconic and widely adopted firearms in the world, used by dozens of militaries , police forces , and paramilitaries worldwide. Many of its prototype weapons, including the G11 , HK CAWS , XM29 OICW , and XM8 , have also become recognizable. HK firearms use blowback operation , short-recoil , roller-delayed blowback , gas-delayed blowback , and short-stroke piston gas operation . HK
1008-507: A vertically tilting barrel also employed in the USP series of self-loading pistols, as well as most modern linkless semi autos. The cold hammer-forged barrel has a polygonal profile while the slide is made from a solid bar of nitro-carburized steel . Following recent trends in modern pistol design, the P2000 makes extensive use of impact-resistant polymers to reduce weight and production costs. As with other recent Heckler & Koch pistol designs,
1080-447: A working model wouldn't be produced until 1888. Later in the 1870s, a Swedish captain called D. H. Friberg patented a design which introduced both flapper-locking and the fully automatic recoil operated machine gun. Furthermore, in 1875 a means of cocking a rifle through recoil was patented through the patent agent Frank Wirth by a German called Otto Emmerich. Finally came Maxim's 1883 automatic recoil operated machine gun which introduced
1152-409: Is a moving part of the action in recoil-operated firearms. In non-recoil-operated firearms, it is generally the entire firearm that recoils. However, in recoil-operated firearms, only a portion of the firearm recoils while inertia holds another portion motionless relative to a mass such as the ground, a ship's gun mount, or a human holding the firearm. The moving and the motionless masses are coupled by
1224-455: Is concern that an inmate may gain control of an officer's pistol, locks the action of the pistol when the magazine is removed, giving officers a way to easily temporarily disable the weapon. Of note, HK created a somewhat less refined version of this for a previous contract for USP pistols for the Department of Corrections, but instead of preventing the trigger bar from moving like in the P2000, in
1296-482: Is fitted to boost the recoil. Recoil-operated designs are broadly categorized by how the parts move under recoil. Long recoil operation is found primarily in shotguns , particularly ones based on John Browning 's Auto-5 action. In 1885 a locked breech, long recoil action was patented by the Britons Schlund and Arthur. In a long recoil action, the barrel and bolt remain locked together during recoil, compressing
1368-429: Is responsible for several innovations in firearms, such as the use of polymers in weapon designs, modern polygonal rifling , the feasibility of high-velocity caseless ammunition in prototype service rifles, and integral rails for handgun attachments. Heckler & Koch products use an internal naming system, consisting of an abbreviation and a two- or three-digit Werknummern designation popularly referred to as
1440-448: Is the inertia operated system, the first practical use of it being the Sjögren shotgun , developed by Carl Axel Theodor Sjögren in the early 1900s, a Swedish engineer who was awarded a number of patents for his inertia operated design between 1900 and 1908 and sold about 5,000 automatic shotguns using the system in 1908–1909. In a reversal of the other designs, some inertia systems use nearly
1512-531: Is the spurred hammer, LEM components and decocking lever. Also seen is the unique rail point, designed for the German issue light. Once specifically unique item added to the P2000 and P2000SK pistols that were delivered to the DHS/ICE contract was the inclusion of a small transponder chip into the left side of the steel insert of the grip frame. This can be seen in the photo of the cutaway training guns below. This chip served as an electronic gun data book, assessable from
SECTION 20
#17328526961591584-452: Is unclear how many were exported to Libya and by whom. On 11 December 2011, federal, state and local Mexican police officers used battle rifles to fire on Ayotzinapa Rural Teachers' College students and peasant organizations to disperse a blockade on Mexican Federal Highway 95D , resulting in the deaths of students Jorge Alexis Herrera and Gabriel Echeverría de Jesús. According to media reports, 7.62×51mm NATO round casings were found at
1656-657: The Bundeswehr . Heckler & Koch developed and produced the Project HK50, a lightweight carbon fiber assault rifle , which became the G36 assault rifle. In addition, Heckler & Koch produced the P8 pistol, derived from its USP handguns produced since 1989. The USP was adopted as the standard sidearm of the Bundeswehr in 1994, and the G36 was adopted as their standard-issue rifle in 1995. As
1728-744: The HK416 . HK replaced the direct impingement system used by the Stoner design on the original M16 with a short-stroke piston operating system. The civilian models are named the MR223 and, in the U.S., the MR556A1. In 2007, United States Secretary of the Army Pete Geren agreed to hold a "dust chamber" test pitting the M4 against the Heckler & Koch HK416 and XM8 , as well as
1800-497: The Heckler & Koch G3 . The success of the G3 rifle prompted HK to transition to the defense industry. HK was owned by Royal Ordnance from 1991 to 2002, and is currently part of the Heckler & Koch Group, comprising Heckler & Koch GmbH, Heckler & Koch Defense, NSAF Ltd., and Heckler & Koch France SAS. The company's motto is " Keine Kompromisse! " (No Compromises!). Nicolas Walewski 's financial holding company CDE has held
1872-618: The Objective Individual Combat Weapon , a planned replacement for the M16 rifle / M203 grenade launcher combination. The OICW was designed to fire 5.56 mm rounds and 25 mm grenades. The kinetic energy component was also developed separately as the XM8 , though both the OICW and XM8 are now indefinitely suspended. Heckler & Koch developed an AR-15 / M4 carbine variant, marketed as
1944-715: The Walther P38 and Beretta 92 , rollers in the MG42 , or a rotating barrel used in the Beretta 8000 and others. An unusual variant is the toggle bolt design of the Borchardt C-93 and its descendant, the Luger pistol . While the short recoil design is most common in pistols, the very first short-recoil–operated firearm was also the first machine gun , the Maxim gun . It used a toggle bolt similar to
2016-574: The West German government's tender for a new infantry rifle for the Bundeswehr with the proposal of the G3 battle rifle , based on the Spanish CETME Model 58 rifle and developed in cooperation with CETME . The German government awarded Heckler & Koch the tender and in 1959 declared the G3 the standard rifle of the Bundeswehr . Later in 1961, Heckler & Koch developed the 7.62×51mm HK21 general-purpose machine gun , based on
2088-409: The blowback method of operation. Short recoil operation differs from long recoil operation in that the barrel and bolt recoil together only a short distance before they unlock and separate. The barrel stops quickly, and the bolt continues rearward, compressing the recoil spring and performing the automated extraction and feeding process. During the last portion of its forward travel, the bolt locks into
2160-419: The "HK 3-digit system". Each letter and digit is assigned a specific meaning outlined in the convention to make them easier to identify and differentiate by name. The HK naming convention is not a fixed convention, but rather a guideline, and not all HK products follow it; this is typically done for marketing purposes or quirks in the weapon's development or intended role. For instance, the HK416 does not use
2232-820: The Browning system were the Remington Model 8 semi-automatic rifle (1906), the Remington Model 11 & "The Sportsman" model (a model 11 with only a two-shell magazine) shotguns, the Frommer Stop line of pistols (1907), and the Chauchat automatic rifle (1915). The short recoil action dominates the world of centerfire semi-automatic pistols , being found in nearly all weapons chambered for high-pressure pistol cartridges of 9×19mm Parabellum and larger, while low-pressure pistol cartridges of .380 ACP and smaller generally use

2304-606: The Combat Defensive Action (CDA) aka Law Enforcement Modification (LEM) mechanism is used versus a SA/DA trigger . The following options are available: The original P2000 manual stated that HK does not recommend the use of +P and +P+ ammunition in P-series pistols: The revised manual (2014) removes this recommendation, stating that P series handguns are designed for brass-cased ammunition, factory-loaded to NATO or SAAMI specifications. The revised manual continues to warn against
2376-652: The G3. In 1966, Heckler & Koch introduced the HK54 machine pistol , which eventually launched in 1969 as the MP5 submachine gun . Two years later, the company introduced the HK33 assault rifle , a smaller version of the G3 chambered in 5.56×45mm NATO . In 1974, Heckler & Koch diversified into two more areas, HK Defense and Law Enforcement Technology and HK Hunting and Sports Firearms. Since then HK has designed and manufactured more than 100 different types of firearms and devices for
2448-495: The LEM variant, which in Germany is referred to as CDA or Combat Defense Action, but oddly enough they also wanted a spurred hammer, side-mounted safety lever and a rear-mounted decocking lever, all three normally associated with DA/SA operation. Below is a cutaway drawing of that specific variant. Though the side-mounted safety lever is omitted to not block the internal components, clearly seen
2520-401: The P2000 is modular to suit individual needs. For instance, the grip is modular with exchangeable backstraps, allowing the user to customize the pistol's grip size and feel. There is a universal accessory rail built into the dust cover in front of the trigger guard that allows for the use of tactical lights, laser pointers and other accessories. This is in contrast with the USP series which uses
2592-408: The USP retrofit, it had a bar that went over the sear, blocking the hammer's forward movement. HK designers moved away from this design when creating it for the P2000, as they found that over time the USP design caused more pressure on the leading edge of the sear against the flat main spring, and as such, a higher failure rate of the flat main spring. As part of the contouring of the P2000 series came
2664-576: The United Kingdom, France, and the United States. Heckler & Koch was founded in 1949 by former Mauser engineers Edmund Heckler , Theodor Koch , and Alex Seidel , who founded the company out of the shuttered Mauser factory in Oberndorf. The company initially produced machine tool and metal parts until 1956 when, in response to a Bundeswehr contract for a new service rifle , HK developed
2736-452: The action, allowing a wide range of shotshells to be used, from standard to magnum loads, as long as they provide the minimum recoil level to compress the spring. Note that the shotgun must be free to recoil for this to work—the compressibility of the shooter's body is sufficient to allow this movement, but firing the shotgun from a secure position in a rest or with the stock against the ground will not allow it to recoil sufficiently to operate
2808-561: The barrel and pushes the barrel back into battery. The method of locking and unlocking the barrel differentiates the wide array of short recoil designs. Most common are the John Browning tilting barrel designs based on either the swinging link and locking lugs as used in the M1911 pistol or the linkless cam design used in the Hi Power and CZ 75 . Other designs are the locking block design found in
2880-409: The barrel backwards, in addition to the recoil energy. This boost provides higher rates of fire and/or more reliable operation. This type of mechanism is also found in some suppressors used on short recoil firearms, under the name gas assist or Nielsen device , where it is used to compensate for the extra mass the suppressor adds to the recoiling parts both by providing a boost and decoupling some of
2952-476: The bolt head, extracts and ejects the cartridge, cocks the hammer, and compresses the return spring. Once the bolt reaches the end of its travel, the return spring provides the force to chamber the next round from the magazine, and lock the bolt closed. Some short-recoil–operated firearms, such as the German MG 42 and MG 3 , use a mechanism at the muzzle to extract some energy from the escaping powder gases to push

Heckler %26 Koch Heckler & Koch GmbH ( HK or H&K ; German pronunciation: [ˌhɛklɐ ʔʊnt ˈkɔx] ) is a German firearms manufacturer that produces handguns , rifles , submachine guns , and grenade launchers . The company is located in Oberndorf am Neckar , Baden-Württemberg , and also has subsidiaries in
3096-470: The breech of a rifle, the breech then being manually pulled the rest of the way back by hand. Around this time, an American by the name of Regulus Pilon is sometimes stated to have patented in Britain a gun that used a limited form of recoil operation. He had three British patents related to firearms around the 1850s to the 1860s; however, all of them refer to a means of dampening recoil in firearms, which wasn't
3168-473: The choice of one or the other. Along the contouring line also came and update to the grips, with a new side grip design that carried over to the MP7 production and a removable and exchangeable rear grip panel, allowing the shooter to customize the grip size to one of four sizes. With this customization also came the recognition of a requirement for ambidextrous use, and the incorporation of a slide release now mounted on
3240-518: The company effectively evaded EU export restrictions when these licensees sold HK weapons to conflict zones including Indonesia , Sri Lanka and Sierra Leone . According to the newspaper Stuttgarter Nachrichten (31 August 2011), as well as the state broadcaster ARD, a large stockpile of G36 assault rifles fell into rebel hands during the August 2011 attack on Muammar Gaddafi 's compound in Tripoli . It
3312-417: The company was unable to secure funded contracts from the German government to support production of either weapon system and became financially vulnerable. The next year, Heckler & Koch was sold to British Aerospace 's Royal Ordnance division. During 1994 and 1995, the German government awarded Heckler & Koch contracts for producing an updated standard assault rifle and updated standard sidearm for
3384-482: The entire firearm as the recoiling component, with only the bolt remaining stationary during firing. Because of this, the inertia system is only applied to heavily recoiling firearms, particularly shotguns. A similar system using inertia operation was then developed by Paolo Benelli in the early 1980s and patented in 1986. With the exception of Sjögren's shotguns and rifles in the early 1900s, all inertia-operated firearms made until 2012 were either made by Benelli or used
3456-535: The factory and used what they salvaged to start a machine tool plant in the vacant factory that became known as the Engineering Office Heckler & Co. On December 28, 1949, the Engineering Office Heckler & Co. changed its name and was registered officially as Heckler & Koch GmbH. Initially the new company manufactured machine tools, bicycle and sewing machine parts, gauges, and other precision parts. In 1956, Heckler & Koch responded to
3528-434: The later introduced P2000SK as well as USP Compact LEM, that won the DHS/ICE contract discussed previously; a massive contract for the company. For that contract and for US civilian importation, the mounting rail was modified again to what was termed the “industry standard”, allowing access to a much wider range of products. Though rarely seen and extremely unusual is the original design request from German Customs. They wanted
3600-457: The lower court's decision, finding that H&K employees knowingly falsified information on the nature and destination of arms sold by the company in order to attain federal export licenses. Recoil operation 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
3672-404: The mechanism was optimized. For example, the M1911 design with factory springs is optimized for a 230-grain (15 g) bullet at factory velocity. Changes in caliber or drastic changes in bullet weight and/or velocity require modifications to spring weight or slide mass to compensate. Similarly the use of blank ammunition will typically cause the mechanism not to work correctly, unless a device
SECTION 50
#17328526961593744-443: The mechanism. Likewise, care must be exercised when modifying weapons of this type (e.g. addition of extended magazines or ammunition storage on the stock), as any sizable increase in weapon mass can reduce the work done from recoil below that required to cycle the action. As the recoil spring returns to its uncompressed state, it pushes the bolt body backward with sufficient force to cycle the action. The bolt body unlocks and retracts
3816-426: The modern age of automatic machine guns. The same forces that cause the ejecta of a firearm (the projectile(s), propellant gas, wad, sabot , etc.) to move down the barrel also cause all or a portion of the firearm to move in the opposite direction. The result is required by the conservation of momentum such that the ejecta momentum and recoiling momentum are equal. These momenta are calculated by: The barrel
3888-643: The one Borchardt later adapted to pistols. Vladimirov also used the short recoil principle in the Soviet KPV-14.5 heavy machine gun which has been in service with the Russian military and Middle Eastern armed forces since 1949. Melvin Johnson also used the short recoil principle in his M1941 Johnson machine gun and M1941 rifle, other rifles using short recoil are LWRCI SMG 45 and LoneStar Future Weapons RM-277R . An alternative design concept for recoil-operated firearms
3960-462: The pressure of the propellant gas. 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

These are placed after (or if a suffix, before) the abbreviation, and denote the generation, form factor , and caliber or munition of the weapon. 9×19mm Parabellum , .40 S&W .45 ACP , etc. The date code is a two-letter combination used to specify the year a weapon was manufactured in. These are not part of the product's name, but are printed for identification directly on
4104-438: The recoil springs. Following this rearward movement, the bolt locks to the rear and the barrel is forced forward by its spring. The bolt is held in position until the barrel returns completely forward during which time the spent cartridge has been extracted and ejected, and a new shell has been positioned from the magazine. The bolt is released and forced closed by its recoil spring, chambering a fresh round. The long recoil system
4176-433: The removal of a side-mounted safety and decocker for DA/SA and in its place was a rear-mounted decocker, which when activated, forces the sear out of its contact point with the hammer. Also, different on the P2000 series was a lack of modularity, in the fact that no longer was the base pistol capable of being converted between DA/SA and LEM (it can be done, but not approved by HK). With different frames, you are either left with
4248-563: The result of a 1999 merger between British Aerospace and Marconi Electronic Systems , Heckler & Koch was owned by the resulting BAE Systems ; it was contracted to refurbish the British Army 's SA80 rifles (which had been manufactured by Royal Ordnance) This contract entailed a modification program to the SA80 series of rifles to address a number of reliability issues with the design. In 2002, BAE Systems restructured and sold Heckler & Koch to
4320-405: The right side of the weapon. Of note, HK recommends that you do not remove the right side slide release for normal maintenance. It is not fitted into a steel insert, only polymer, and repeated removal will loosen the tolerances, resulting in a “rattle” of that part against the weapon. The P2000 is a short recoil -operated locked breech pistol with a modified Browning -type linkless cam action with
4392-598: The rival FN SCAR design. The Heckler & Koch XM8 and FN SCAR had the fewest failures in the test, closely followed by the HK416, while the M4 had by far the most. In 2007, the Norwegian Army became the first to field the HK416 as a standard-issue rifle. HK sells its pistols in the United States to both law enforcement and civilian markets, through its HK USA subsidiary. The company has locations in Virginia , New Hampshire , and Georgia . Heckler & Koch has produced

#17328526961594464-508: The sale of 4,700 rifles and large quantities of ammunition. H&K was issued a fine of 3.7 million euros, and the two men received suspended sentences of 17 and 22 months. The spokesman of the Presidency of the Republic of Mexico, Jesús Ramírez Cuevas, said that the amount of the fine should go to the victims and their families. On 30 March 2021, Germany's Federal Court of Justice (BGH) upheld
4536-482: The scene, matching those used by H&K G3 rifles. In Iguala and Cocula , corrupt police officers and cartelmen are known to have used H&K G36 rifles during the 2014 Iguala mass kidnapping on 26–27 September 2013. At least six teaching students were murdered by cartelmen and corrupt local police, and 43 others are missing and presumed dead. Other than the six identified persons, no other bodies have been found, and they are believed to have been incinerated. As
4608-431: The slide, a minor upgrade came in the form of a polymer buffer that works in concert with the extractor spring. It reinforces that spring, reducing its wear and providing more force against the extractor, while also preventing the extractor from over extension. All P2000 pistols have the ability to accept an optional retro-fit magazine disconnect kit. This design feature, popular with US Department of Corrections where there
4680-517: The success of the USP series, came the P2000. Originally designed for the German Customs organization, it was basically a requirement for an updated, more ergonomic version of the USP Compact, contoured for carry, adding a customizable grip and replacing the proprietary mounting rail with the one specific to a light they requested. Beyond securing this contract, it was the P2000, along with a number of
4752-405: The suppressor's mass from the firearm's recoiling parts. Muzzle boosters are also used on some recoil-operated firearms' blank-firing attachments to normalize the recoil force of a blank round (with no projectile) with the greater force of a live round, in order to allow the mechanism to cycle properly. Several revolvers use recoil to cock the hammer and advance the cylinder. In these designs,
4824-424: The use of steel- or aluminum-cased ammunition. The P2000 SK model is a smaller "sub-compact" version of the P2000. American versions of the P2000SK will accept the longer USP Compact magazines which provide higher capacities; up to 13 9 mm rounds and 12 .40 S&W/.357 SIG cartridges. Some of the advantages of its compact size will be compromised as these longer magazines will protrude approximately 1/2" below
4896-808: The weapon itself. They are only used on handguns. Heckler & Koch handguns produced at HK's German facilities are marked with "DE", Germany's ISO 3166-1 code. Handguns manufactured in HK facilities outside Germany, or those produced in Germany before 2008, do not have the DE marking. Heckler & Koch long arms mostly follow a set of shared trigger group standards for selective fire and safety , with corresponding markings and pictograms. H&K has been accused of shipping small arms to conflict regions such as Bosnia and Nepal , and has licensed its weapons for production by governments with poor human rights records such as Sudan , Thailand and Myanmar . It has been argued that
4968-506: The world's military and law enforcement organizations as well as sports shooters and hunters. In 1990, Heckler & Koch completed two decades of development of their revolutionary caseless weapon system and produced prototypes of the G11 rifle. The company also produced prototypes of the G41 assault rifle intended for the Bundeswehr . Due to the international political climate at the time (East and West Germany uniting and defense budget cuts)
5040-538: Was awarded a major handgun contract for the United States Department of Homeland Security , worth a potential $ 26.2 million for up to 65,000 handguns. This contract ranks as the single largest handgun procurement contract in U.S. law enforcement history. HK was contracted by the United States Army to produce the kinetic energy subsystem (see: kinetic projectiles or kinetic energy penetrator ) of
5112-475: 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 viable. The earliest mention of recoil operation in the British patent literature is a patent by Joseph Whitworth filed in 1855 which proposed to use recoil to partially open
5184-533: Was invented in the late 19th century and dominated the automatic shotgun market for more than half that century before it was supplanted by new gas-operated designs. While Browning halted production of the Auto-5 design in 1999, Franchi still makes a long-recoil–operated shotgun line, the AL-48 , which shares both the original Browning action design, and the "humpbacked" appearance of the original Auto-5. Other weapons based on
