Improvised firearms (sometimes called zip guns, pipe guns, or slam guns) are firearms manufactured by an entity other than a registered firearms manufacturer or a gunsmith. Improvised firearms are typically constructed by adapting existing materials to the purpose. They range in quality, from crude weapons that are as much a danger to the user as the target, to high-quality arms produced by cottage industries using salvaged and repurposed materials. [1] [2] [3]
Improvised firearms may be used as tools by criminals and insurgents and are sometimes associated with such groups; [4] [5] other uses include self-defense in lawless areas and hunting game in poor rural areas. [6]

Zip guns are generally crude homemade firearms consisting of a barrel, breechblock and a firing mechanism. For small, low-pressure cartridges, like the common .22 caliber rimfire cartridges, even very thin-walled tubing can work as a barrel, strapped to a block of wood for a handle. A rubber band that the shooter pulls back and releases to fire can power the firing pin. Weak tubing can result in a firearm that can be as dangerous to the shooter as the target; a poorly fitting smoothbore barrel provides little accuracy and is liable to burst upon firing. [1] The better designs use heavier pipes and spring-loaded trigger mechanisms. Larger zip guns, such as homemade shotguns called tumbera (Argentina), bakakuk [7] (Malaysia), or sumpak [8] (Philippines) are also made of improvised materials like nails, steel pipes, wooden pieces, bits of string, etc.
Pen guns are zip gun-like firearms that resemble ink pens. [9] [10] They generally are of small caliber (e.g., .22 LR, .25 ACP, .32 ACP, etc.) [11] [12] [13] and are single shot. [12] [14] Early examples of pen guns were pinfired, but modern designs are rimfire or centerfire. [9] Some pen guns are not designed to fire regular cartridges, but rather blank cartridges, signal flares, or tear gas cartridges. [9] [15]
In the United States, pen guns that fire bullets or shot cartridges do not require a reconfiguration to fire, (e.g., folding to the shape of a pistol) and are federally regulated as an Any Other Weapon (Title II). They require registration under the National Firearms Act and a tax in the amount of $200 to manufacture or $5 to transfer is levied. [15] [16]
Pipe guns were first seen in the Philippines during World War II. [17] The "paliuntod" is a type of improvised shotgun commonly used by guerrillas and the joint American and Filipino soldiers who remained behind after Douglas MacArthur's withdrawal. Made of two pieces of pipe that fit snugly together, the "paliuntod" were simple, single shot guns. These pipe guns are still in use by both criminals and rebels in the Philippines. [18] [19]
In 1946, pipe guns were patented in the United States by Iliff D. "Rich" Richardson, who fought with the Filipino insurgents during the Japanese occupation. [17] [20] Made by "Richardson Industries" as the "Model R5 Philippine Guerrilla Gun", these 12 gauge shotguns sold for $7 at the time. [17]
Improvised versions are made by using two pipes and an end-cap; they usually fire shotgun shells. To fire the gun, the user inserts a shotgun shell into the smaller diameter pipe, places the smaller pipe into the larger diameter pipe, and forcefully slides it back until the shell's primer makes contact with a fixed firing pin located inside the end-cap. [4] [5] Other improved versions use improvised detachable magazines. [21]
Flare guns have also been converted to firearms. This may be accomplished by replacing the (often plastic) barrel of the flare gun with a metal pipe strong enough to chamber a shotgun shell, or by inserting a smaller-bore barrel into the existing barrel (such as with a caliber conversion sleeve) to chamber a firearm cartridge, such as a .22 Long Rifle. [22] [23]
More advanced improvised guns can use parts from other gun-like products. One example is the cap gun. A cap gun can be disassembled, and a barrel added, turning the toy gun into a real one. A firing pin can then be added to the hammer, to concentrate the force onto the primer of the cartridge. If the cap gun has a strong enough hammer spring, the existing trigger mechanism can be used as-is; otherwise, rubber bands may be added to increase the power of the hammer. [24]
Air guns have also been modified to convert them to firearms. The Brocock Air Cartridge System, for example, uses a self-contained "cartridge" roughly the size of a .38 Special cartridge, which contains an air reservoir, valve, and a .22 caliber (5.5 mm) pellet. Examples of BACS airguns converted to firearms, either by drilling the barrel out to fire a .38 Special cartridge or by altering the cylinder to accept .22 caliber cartridges, have been used in a number of crimes. Blank-firing guns can also be converted by adding a barrel, although the low-quality alloys used for cheaper blank-firing guns may break with the pressures and stresses of a real bullet being fired. [25]
Some more complex improvised firearms are not only well-built, but also use mimicry as camouflage, taking the appearance of other items. Improvised firearms in the form of flashlights, cellular telephones, canes and large bolts have all been seized by law enforcement officials.[ citation needed ] Most of these are .22 caliber rimfires, but flashlight guns have been found ranging from small models firing .22 Long Rifle to larger ones chambered for .410 bore shotgun shells. [26] [27]
While most improvised firearms are single-shot, multiple-shot versions are also encountered. The simplest multi-shot zip guns are derringer-like, and consist of a number of single-shot zip guns attached together. The pepper-box design is also used in homemade guns because it is relatively easy to make out of a bundle of pipes or a steel cylinder. In late 2000, British police encountered a four-shot .22 LR zip gun disguised as a mobile phone, where different keys on the keypad fire different barrels. Because of this discovery, mobile phones are now X-rayed by airport screeners worldwide. Authorities believe they were manufactured in Croatia, and they still turned up in Europe as late as 2004, according to a report by Time magazine. [28] [29]
Homemade submachine guns are often made by copying existing designs, or by adapting simple, open-bolt actions and leveraging commonly available hardware store parts. [2] [30]
The Błyskawica (Polish for lightning) was a submachine gun produced by the Armia Krajowa, or Home Army, a Polish resistance movement fighting the Germans in occupied Poland. Together with a Polish version of the Sten sub-machine gun, with which it shares some design elements, it was the only weapon mass-produced covertly in occupied Europe during World War II.
The Bechowiec (also known as the Bechowiec-1) was a Polish World War II submachine gun developed and produced by the underground Bataliony Chłopskie (BCh, Peasants' Battalions) resistance organisation. It was designed in 1943 by Henryk Strąpoć and was produced in underground facilities in the area of Ostrowiec Świętokrzyski. Its name was coined after the Bataliony Chłopskie organization members who were informally called bechowiec (plural: bechowcy).
The Borz (Борз, Chechen for "wolf") submachine gun is one of a number of improvised firearms produced in Chechnya. It was produced in small numbers from 1992 to 1999. It was used primarily by Chechen separatists. It is named after the Borz (wolf) because of its position as Chechnya's national animal.
The Carlo (also referred to as Carl Gustav) is a submachine gun manufactured by small workshops in the West Bank. The design has been inspired by the Swedish Carl Gustav m/45 and its Egyptian Port Said variant; however, the similarity is often only passing. Produced in several locations and often with second-hand gun parts, the specifications are not uniform. Typically the weapon is automatic. Often chambered for 9mm Parabellum pistol cartridges, variants for .22 LR, .32 ACP, 9mm Makarov, and 5.56 NATO are also produced. The weapon itself is cheap to manufacture but is inaccurate and prone to jamming and misfires. [31] [32] [33] [34] [35] [36]
The FP-45 Liberator and the Deer gun were crude zip gun-like single-shot pistols or derringers manufactured by the United States government for use by resistance forces in occupied territories, during World War II and the Vietnam War, respectively.
The FP-45 was designed to be cheaply and quickly mass-produced. It had just 23 largely stamped and turned steel parts that were cheap and easy to manufacture. It fired the .45 ACP pistol cartridge from an unrifled barrel and five rounds of .45 ACP ammunition could be stored in the pistol grip. Due to this limitation, it was intended for short range use, 1–4 yards (0.91–3.66 m). Its maximum effective range was only about 25 ft (7.6 m). At longer range, the bullet would begin to tumble and stray off course. The original delivered cost for the FP-45 was USD$2.10/unit, lending it the nickname "Woolworth pistol". [37]
The Deer gun fired the 9mm Parabellum pistol cartridge. It was made of cast aluminium, with the receiver formed into a cylinder at the top of the weapon. The striker protruded from the rear of the receiver and was cocked in order to fire, and a plastic clip was placed there to prevent an accidental discharge, as the Deer gun had no mechanical safety. The grip had raised checkering, was hollow, and had space for three 9mm Parabellum rounds and a rod for clearing the barrel of spent cases. The Deer gun lacked any marking identifying manufacturer or user, in order to prevent tracing of the weapons, and all were delivered in unmarked polystyrene boxes with three 9mm Parabellum rounds and a series of pictures depicting the operation of the gun. A groove ran down a ramp on top for sighting. The barrel unscrewed for loading and removing the empty casing. A cocking knob was pulled until cocked. The aluminium trigger had no trigger guard.
In 2012, the U.S.-based group Defense Distributed disclosed plans to design a working plastic gun that could be downloaded and reproduced by anybody with a 3D printer. [38] [39] The Liberator is a physible, 3D-printable single shot handgun, the first such printable firearm design made widely available online. [40] [41] [42] The open source firm Defense Distributed designed the gun and released the plans on the Internet on May 6, 2013. The plans were downloaded over 100,000 times in the two days before the United States Department of State demanded that Defense Distributed retract the plans, deeming them a violation of the Arms Export Control Act. [43] [44] [45] In 2015, Defense Distributed founder Cody Wilson sued the United States government on free speech grounds and in 2018 the Department of Justice settled, acknowledging Wilson's right to publish instructions for the production of 3D-printed firearms. [46] [47]
Defense Distributed has also designed a 3D printable AR-15 type rifle lower receiver (capable of lasting more than 650 rounds) and a variety of magazines, including for the AK-47. [48] In 2013 a California company, Solid Concepts, demonstrated a 3D printed version of an M1911 pistol made of metal, using an industrial 3D printer. [49]
In the United States, creating an improvised firearm for personal use does not require licensure, registration, a background check, or the stamping of a serial number, but the firearm created must be detectable by a metal detector per federal law. [50] [51] California, however, passed a law in 2016 that requires anyone planning to build a homemade gun to obtain a serial number from the state (de facto registration) and pass a background check. [52] However, such firearms are often illegal in other jurisdictions and are commonly associated with gangs, where they may be used to facilitate violent crime, such as homicide. [1] In other cases, they may be used for other criminal activities not necessarily related to violent crime, such as illegal hunting of game. [6] Improvised firearms are most commonly encountered in regions with restrictive gun control laws.[ citation needed ] While popular in the United States in the 1950s, the "zip gun" has become less common.
A Khyber Pass copy is a firearm manufactured by cottage gunsmiths in the Khyber Pass region between Pakistan and Afghanistan. The area has long had a reputation for producing unlicensed, homemade copies of firearms using whatever materials are available –more often than not, railway rails, scrap motor vehicles, and other scrap metal. The quality of such firearms varies widely, ranging from as good as a factory-produced example to dangerously poor. Much of the gunsmithing is centered around the town of Darra Adam Khel.
In India, use of improvised country-made pistols is widespread, especially in the regions of Bihar and Purvanchal. The manufacture of these weapons has become a cottage industry, and the components are often manufactured from scrap material; examples include gun barrels fashioned from truck steering columns.
The rebels of the Mau Mau Rebellion (1952–1960) used many different improvised weapons. [53] [54] [55] [56]
In areas like South Africa, improvised firearms are more common. In a study of Zululand District Municipality, South Africa, it was found that most improvised firearms were crude, 12-gauge shotguns, with a simple pull-and-release firing mechanism; like .22 rimfire cartridges, shotgun shells operate at low pressures, making them more suited for use in weak, improvised barrels. [25]
Even in the absence of commercially available ammunition, homemade black powder weapons can be used; such firearms were the subject of a crackdown in the People's Republic of China in 2008. [6] In many areas of Africa, such as Zimbabwe, poachers use improvised muskets and shotguns loaded with black powder stolen from mines. [57]
The city of Danao in Cebu, Philippines, has been making improvised firearms so long that the makers have become legitimate, and are manufacturing firearms for sale. The Danao makers manufacture .38 and .45 caliber revolvers, and semi-automatic copies of the Ingram MAC-10 and Intratec TEC-DC9. [2]
In 2004, an "underground weapons factory" was seized in Melbourne, Australia, yielding among other things a number of silenced copies of the Owen submachine gun, suspected to have been built for sale to local gangs involved in the illegal drug trade. [58]
Improvised firearms have also been used in Russia, [59] [60] where they have been used in domestic homicides and terrorism.
Improvised firearms were used by the perpetrator of the Halle synagogue shooting; the homemade shotgun and "Luty" submachine gun repeatedly malfunctioned. The attacker, an antisemitic neo-Nazi terrorist, said while livestreaming the attack, "I have certainly managed to prove how absurd improvised weapons are." [61]
In Italy, Naples, Caivano, multiple illegal weapons by the notorious Camorra were found during a raid, among them was a homemade 22-caliber gun, 400 homemade shells (likely for another gun such as a lupara, another type of gun that is often homemade), a homemade suppressor, and a pen gun. [62]
In Japan, an improvised shotgun was used in the assassination of Shinzo Abe, former prime minister of Japan, on 8 July 2022. [63]
A carbine is a long gun that has a barrel shortened from its original length. Most modern carbines are rifles that are compact versions of a longer rifle or are rifles chambered for less powerful cartridges.
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries.
In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also with much slower rates of fire.
A submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun. As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns.
The .45 ACP, also known as .45 Auto, .45 Automatic, or 11.43×23mm is a rimless straight-walled handgun cartridge designed by John Moses Browning in 1904, for use in his prototype Colt semi-automatic pistol. After successful military trials, it was adopted as the standard chambering for Colt's M1911 pistol. The round was developed due to a lack of stopping power experienced in the Moro Rebellion in places like Sulu. The issued ammunition, .38 Long Colt, had proved inadequate, motivating the search for a better cartridge. This experience and the Thompson–LaGarde Tests of 1904 led the Army and the Cavalry to decide that a minimum of .45 caliber was required in a new handgun cartridge.
The .380 ACP, also known as .380 Auto, .380 Automatic, or 9×17mm, is a rimless, straight-walled pistol cartridge that was developed by firearms designer John Moses Browning. The cartridge headspaces on the mouth of the case. It was introduced in 1908 by Colt, for use in its new Colt Model 1903 Pocket Hammerless semi-automatic, and has been a popular self-defense cartridge ever since, seeing wide use in numerous handguns. Other names for .380 ACP include 9mm Browning, 9mm Corto, 9mm Kurz, 9mm Short, and 9mm Browning Court. It should not be confused with .38 ACP. The .380 ACP does not strictly conform to cartridge naming conventions, named after the diameter of the bullet, as the actual bullet diameter of the .380 ACP is .355 inches.
The 9×19mm Parabellum is a rimless, centerfire, tapered firearms cartridge.
An automatic firearm or fully automatic firearm is a self-loading firearm that continuously chambers and fires rounds when the trigger mechanism is actuated. The action of an automatic firearm is capable of harvesting the excess energy released from a previous discharge to feed a new ammunition round into the chamber, and then igniting the propellant and discharging the projectile by delivering a hammer or striker impact on the primer.
The .410 bore (10.4 mm) is one of the smallest caliber of shotgun shell commonly available. A .410 bore shotgun loaded with shot shells is well suited for small game hunting and pest control. The .410 started off in the United Kingdom as a garden gun along with the .360 and the No. 3 bore (9 mm) rimfire, No. 2 bore (7 mm) rimfire, and No. 1 bore (6 mm) rimfire. .410 shells have similar base dimensions to the .45 Colt cartridge, allowing many single-shot firearms, as well as derringers and revolvers chambered in that caliber, to fire .410 shot shells without any modifications.
The Beretta M12 is a 9×19mm Parabellum caliber submachine gun designed by Beretta. Production started in 1959, the first users were the Italian Carabinieri, Italian State Police and the Guardia di Finanza, though in limited numbers; it was only widely issued beginning in 1978, replacing the old Beretta MAB. In 1962 the Italian Army bought a limited number of Franchi LF-57 submachine guns, judged better than the M12 but never issued to the troops, and only in 1992 the M12S2 variant was introduced, in very limited numbers. The Italian Air Force bought instead many M12S and M12S2 for the airport security units. However, the weapon had a higher initial success in the Arab countries and South America.
The Jatimatic is a Finnish 9×19mm Parabellum submachine gun developed in the late 1970s and early 1980s by Jali Timari. The submachine gun made its debut in 1983. The Jatimatic was manufactured in very limited numbers initially by Tampereen Asepaja Oy of Tampere and later—Oy Golden Gun Ltd. The firearm was designed primarily for police, security forces and armored vehicle crews. It was never adopted into service by the Finnish Defence Forces, although the later GG-95 PDW version was tested by the FDF in the 1990s.
An antique firearm is a term used to describe a firearm that was designed and manufactured prior to the beginning of the 20th century. Although the exact definition of what constitutes an "antique firearm" varies between countries, the advent of smokeless powder or the start of the Boer War are often used as cut-off dates. Antique firearms are usually collected because of their historical interest and/or their monetary value.
A handgun is a firearm designed to be usable with only one hand. It is distinguished from a long barreled gun which needs to be held by both hands and braced against the shoulder. Handguns have shorter effective ranges compared to long guns, and are much harder to shoot accurately. While most early handguns are single-shot pistols, the two most common types of handguns used in modern times are revolvers and semi-automatic pistols, although other handguns such as derringers and machine pistols also see infrequent usage.
The KRISS Vector is a series of weapons based upon the parent submachine gun design developed by the American company KRISS USA, formerly Transformational Defense Industries (TDI).
The QCW-05 is a suppressed bullpup submachine gun, manufactured and developed by the People's Liberation Army (PLA) 208 Research Institute and Jianshe Industries (Group) Corporation of Chongqing under the China South Industries Group for the People's Liberation Army Ground Force, the People's Liberation Army Special Operations Forces and the People's Armed Police. This weapon is designed for the 5.8×21mm DCV05 sub-sonic round that is also used by the QSW-06 Silenced Pistol.
Title II weapons, or NFA firearms, are designations of certain weapons under the United States National Firearms Act (NFA).
The 9×25mm Mauser is a cartridge developed for the Mauser C96 service pistol around 1904 by DWM. Mauser pistols in this relatively powerful caliber were primarily intended for export to Africa, Asia, and South America. The 9mm Mauser Export cartridge was produced specifically for Mauser pistols and carbines made from 1904 to 1914 and then later from approximately 1930 to 1945 for submachine guns chambered for this caliber.
Chiappa Firearms, Armi Sport di Chiappa, is an Italian firearms manufacturing company based in Brescia. It was founded in 1958 by Ezechiele Chiappa as Armi Sport. Total unit production is around 60,000 per year. Its U.S. headquarters are in Dayton, Ohio.
The 7.63×25mm Mauser round is a bottleneck, rimless, centerfire cartridge, originally developed for the Mauser C96 service pistol. This cartridge headspaces on the shoulder of the case. It later served as the basis for the 7.62mm Tokarev cartridge commonly used in Soviet and Eastern Bloc weapons.
A pen gun is a firearm that resembles an ink pen. They generally are of small caliber and are single shot. Early examples of pen guns were pinfired, but modern designs are rim or centerfire. Some pen guns are not designed to fire regular cartridges, but rather blank cartridges, signal flares, or tear gas cartridges.
