The [[Military Armament Corporation]] '''Model 10''', officially abbreviated as "'''M10'''" or "'''M-10'''",<ref name="Operation and Maintenance Manual">{{cite web |url=http://stevespages.com/pdf/mac_10.pdf |title=Operation and Maintenance Manual: Military Armament Corporation |publisher=Military Armament Corporation}}</ref> and more commonly known as the '''MAC-10''', is a compact, [[Blowback (arms)|blowback operated]] [[machine pistol]]/[[submachine gun]] that was developed by [[Gordon Ingram]] in 1964. It is chambered in either [[.45 ACP]] or [[9×19mm Parabellum|9mm]]. A two-stage suppressor by Sionics was designed for the MAC-10, which not only abates the noise created but makes it easier to control on full automatic (although it also makes the gun far less compact and concealable).<ref>{{cite book |title=Modern Warfare |editor1-last=Dartford |editor1-first=Mark |year=1985 |publisher=Marshall Cavendish Books |location=London |isbn=0-86307-325-5 |url-access=registration |url=https://archive.org/details/modernwarfare0000unse }}</ref>

Military Armament Corporation never used the "MAC-10" nomenclature in its catalogues or sales literature, but "MAC-10" is frequently used by [[Title II weapons|Title II]] dealers, gun writers, and collectors.<ref name="MAC-10 name origin">{{cite news |last1=Iannamico |first1=Frank |title=Manufacturing History of Ingram-MAC Type Firearms |url=http://smallarmsreview.com/display.article.cfm?idarticles=3191 |access-date=25 February 2025 |work=Small Arms Review Magazine |issue=20 |publisher=Chipotle Publishing, LLC |date=January 2016 |archive-url=https://web.archive.org/web/20210927183442/http://www.smallarmsreview.com/display.article.cfm?idarticles=3191 |archive-date=27 September 2021 |url-status=bot: unknown }}</ref> For a decade, the semi-automatic pistol version of the weapon was forbidden in the U.S. under the assault weapons ban enacted by Congress in 1994.

==Design==
The MAC-10 is built predominantly from steel stampings. A notched cocking handle protrudes from the top of the [[receiver (firearms)|receiver]], and turning the handle 90°, locks the bolt, and acts as an indicator the weapon is unable to fire. The MAC-10 has a [[telescoping bolt]], which wraps around the rear face of the barrel. This allows a more compact weapon and balances the weight of the weapon over the pistol grip, where the magazine is located. The MAC-10 fires from an [[open bolt]], and the light weight of the bolt results in a rapid rate of fire. In addition, this design incorporates a built-in feed ramp as part of the trigger guard (a new concept at the time) and, to save on cost, the magazine design was recycled from the [[M3 submachine gun|M3 Grease Gun]]. The barrel is threaded to accept a [[suppressor]], which works by reducing the discharge's sound without attempting to reduce the speed of the [[bullet]]. The .45 ACP models are well-suited for this, as most .45 loads are naturally subsonic, as opposed to the specialized subsonic loads usually required for suppressed 9mm weapons. At the suggestion of the [[United States Army]], the suppressor also acts as a foregrip to inhibit [[muzzle rise]] when fired. Ingram added a small bracket with a small strap beneath the muzzle to aid in controlling recoil during [[fully automatic]] fire. The original rate of fire for the MAC-10 in .45 ACP is approximately 1090 rounds per minute.{{cn|date=May 2024}} That of the 9mm is approximately 1250, and that of the smaller [[MAC-11]] in [[.380 ACP]] is 1500 rounds per minute.<ref name="McNab2011">{{cite book|last=McNab|first=Chris|title=The Uzi Submachine Gun|url=https://books.google.com/books?id=aWbTl02k5jYC&pg=PA69|date=20 November 2011|publisher=Osprey Publishing|isbn=978-1-84908-906-7|page=69}}</ref>

Noting the weapon's poor accuracy, in the 1970s, International Association of Police Chiefs weapons researcher David Steele described the MAC series as "fit only for combat in a phone booth".<ref name="Lewis2011">{{cite book|author=Jack Lewis|title=Assault Weapons|url=https://books.google.com/books?id=s2AbzqChZBYC&pg=PA79|date=28 February 2011|publisher=Gun Digest Books|isbn=978-1-4402-2400-3|pages=79–}}</ref>

===Suppressor===
The primary reason for the original M10 finding recognition was its revolutionary sound suppressor designed by [[Mitchell WerBell III]] of [[Sionics]]. This suppressor has a two-stage design, with the first stage being larger than the second. This uniquely shaped suppressor gives the MAC-10 a very distinctive look. It is also very quiet, to the point that the bolt can be heard cycling, along with the suppressed report of the weapon's discharge, though only if subsonic rounds are used (standard .45 ACP rounds are subsonic). The suppressor, when used with a [[Nomex]] cover, creates a place to hold the firearm with the secondary hand, making it easier to control. During the 1970s, the United States placed restrictions on the export of suppressors, and a number of countries canceled their orders as the effectiveness of the MAC-10's suppressor was one of its main selling points. This was one factor that led to the bankruptcy of Military Armament Corporation, another being the company's failure to recognize the private market.{{Clarify|reason=|date=January 2021}} The original Sionics suppressor is 11.44{{spaces}}inches in length, 2.13{{spaces}}inches in overall diameter, and weighs 1.20 pounds.<ref name="Walker2012">{{cite book|last=Walker|first=Robert E.|title=Cartridges and Firearm Identification|url=https://books.google.com/books?id=SJYjP_tJ9_wC&pg=PA210|year=2012|publisher=CRC Press|isbn=978-1-4665-0206-2|pages=210, 436}}</ref>

===Calibers and variants===
While the original M10 was available chambered for either .45 ACP or 9mm, the M10 is part of a series of machine pistols, the others being the [[MAC-11|MAC-11/M-11A1]], which is a scaled-down version of the M10 chambered in .380 ACP (9×17mm); and the M-11/9, which is a modified version of the M-11 with a longer receiver chambered in 9×19mm, later made by SWD (Sylvia and Wayne Daniel), [[Cobray Company|Leinad]] and Vulcan Armament. Law enforcement bureaucracies such as the [[Minnesota Bureau of Criminal Apprehension]] (BCA) consider MAC-11 variants such as the Leinad PM-11 to be part of the "MAC-10 class pistol".<ref>{{cite news |first1=Lou |last1=Raguse |title=New warrants in Idd's case reveal car search and investigation of possible link to brother's case |url=https://www.msn.com/en-us/news/crime/new-warrants-in-idds-case-reveal-car-search-and-investigation-of-possible-link-to-brothers-case/ar-BB1cJoAX |access-date=14 January 2021 |work=MSN News |agency=Kare 11 |date=14 January 2021 |archive-url=https://archive.today/20210114073440/https://www.msn.com/en-us/news/crime/new-warrants-in-idds-case-reveal-car-search-and-investigation-of-possible-link-to-brothers-case/ar-BB1cJoAX |archive-date=14 January 2021 |quote=And they found a backpack on the passenger side that had ammunition and "Leinad PM-11 high capacity pistol."

In the United States, machine guns are [[National Firearms Act]] items. As the Military Armament Corporation was in bankruptcy, a large number of incomplete sheet metal frame flats were given serial numbers and then bought by a new company, RPB Industries. Some of the previously completed guns, which were already stamped with MAC, were then stamped with RPB on the reverse side, making it a "double stamp" gun.{{citation needed|date=November 2022}}

RPB Industries made many open-bolt semi-automatic and sub-machine guns before the [[Bureau of Alcohol, Tobacco, Firearms and Explosives]] (ATF) seized roughly 200 open-bolt semi-autos during the drug wars of 1981.<ref>{{Cite web |last=L. DeNiro |first=Vincent |date=February 20, 2024 |title=Rare Full Auto M-10 (Aka MAC-10) .45 ACP Carbine |url=https://www.firearmsnews.com/editorial/m10-full-auto-for-sale-rare/491652 |website=Firearms News}}</ref> The ATF insisted that all future semi-automatic firearms were to be manufactured with a closed-bolt design as the open-bolt semi-automatics were considered too easy to illegally convert to full automatic operation.<ref name="Walker2012"/>

A semi-automatic variant, the MkIII/IV/V was marketed to South American countries where "military" calibers were forbidden for civilian sales were chambered in .30/.41/.50 Ingram and available as semi-automatic pistols/carbines.<ref>{{Cite web|url=https://werewolf0001.livejournal.com/717328.html|title=Инграм|website=werewolf0001.livejournal.com}}</ref>

Wayne Daniel, a former RPB machine operator, purchased much of their remaining inventory and formed SWD, designing a new weapon which was more balanced, available either fully or semi-automatic with his new BATFE-approved closed bolt design.<ref name="Larson2011">{{cite book|last=Larson|first=Erik|author-link=Erik Larson (author)|title=Lethal Passage: The Story of a Gun|url=https://books.google.com/books?id=FzV82AD3GlQC&pg=PA253|date=27 July 2011|publisher=Knopf Doubleday Publishing Group|isbn=978-0-307-80331-3|page=253}}</ref>

There are several carbine versions of the M-11/9 and Cobray and SWD manufactured a smaller version chambered in .380 ACP as a semiautomatic pistol called the M-12.<ref name="Shideler2011">{{cite book|last=Shideler|first=Dan|title=Gun Digest 2012|url=https://books.google.com/books?id=HEjWeu2XJlEC&pg=PA54|year=2011|publisher=Gun Digest Books|location=Iola, Wisconsin|isbn=978-1-4402-1447-9|page=54}}</ref>

Today, while the civilian manufacture, sale and possession of post-1986 select-fire MAC-10 and variants is prohibited, it is still legal to sell templates, tooling and manuals to complete such conversions. These items are typically marketed as being "post-sample" materials for use by Federal Firearm Licensees for manufacturing/distributing select-fire variants of the MAC-10 to law enforcement, military and overseas customers.<ref>{{cite web | url = http://www.fullautoguns.com | title = Select-Fire (Fully Automatic) conversion information | access-date = 2020-10-07 | archive-date = 2015-06-20 | archive-url = https://web.archive.org/web/20150620123116/http://www.fullautoguns.com/ | url-status = dead }}</ref>

==1994 assault weapons ban in the U.S.==
The semi-automatic civilian pistol version of the MAC-10, which operates differently from its military counterpart, fell under the [[Federal Assault Weapons Ban|1994 Assault Weapons Ban]]. The ban – which [[sunset provision|expired]] in 2004 – enacted various requirements that defined an [[assault weapon]]. The MAC-10 was named directly in the ban, and it failed three of the requirements: 
#A semi-automatic version of an automatic firearm,
#A manufactured weight of 50 ounces (1.4{{spaces}}kg) or more when the pistol is unloaded. The MAC-10 weighs 100.16 oz (2.84{{spaces}}kg),<ref name="Spitzer2001">{{cite book|last=Spitzer|first=Robert J.|title=The Right to Bear Arms: Rights and Liberties Under the Law|url=https://books.google.com/books?id=kYKrIwceQ1UC&pg=PA96|date=1 January 2001|publisher=ABC-CLIO|isbn=978-1-57607-347-6|pages=96–97}}</ref> and
#A threaded barrel to attach barrel extender, flash suppressor, handgrip, or suppressor

Additionally, the magazine capacity is 32 rounds. In response, Wayne Daniel redesigned the M-11 by eliminating the threaded barrel and creating a new magazine release that would only allow the firearm to accept a new 10-round magazine, as the 1994 Assault Weapons Ban mandated. The new firearm was called the PM11/9.<ref name="RothKoper1999">{{cite book|last1=Roth|first1=Jeffrey A.|last2=Koper|first2=Christopher S.|title=Impacts of the 1994 Assault Weapons Ban, 1994–96|url=https://books.google.com/books?id=pb2RAAAAMAAJ|year=1999|publisher=U.S. Department of Justice, Office of Justice Programs, National Institute of Justice|page=3}}</ref>

===BXP===
The [[Milkor BXP|BXP]] is a 9{{spaces}}mm submachine gun developed in the mid-1980s by the South African company Mechem (currently a division of Denel, formerly under ARMSCOR) and brought into production in 1984. Due to international arms embargoes of Apartheid South Africa, the country was forced to design and manufacture their own weapons. The weapon was intended for use by security forces. The manufacturing rights have changed hands several times, passing from Mechem to Milkor Marketing and later to Truvelo Armoury, the current manufacturer ({{as of|lc=y|2009}}).{{Citation needed|date=February 2022}}

===Cobra carbine===
The Cobra carbine is a semi-automatic firearm of Rhodesian origin manufactured during the [[Rhodesian Bush War]] Era as a self-defense weapon for farmers and is chambered for the 9×19mm Parabellum round. The layout of this weapon is somewhat based on the [[Uzi]] submachine gun.<ref name="Cobra">{{cite web|url=http://www.guncity.co.nz/9mm-cobra-rhodesian-mac10-uzi-hybird-xidp156426.html |title=9mm Cobra, Rhodesian MAC-10/Uzi Hybird [sic] |work=Gun City Gun Shop |location=Christchurch, New Zealand |url-status=dead |archive-url=https://web.archive.org/web/20090119142310/http://www.guncity.co.nz/9mm-cobra-rhodesian-mac10-uzi-hybird-xidp156426.html |archive-date=19 January 2009}}</ref>

===Patria submachine gun===
The ''Pistola Ametralladora Patria'' is a close copy of the MAC-10 and features a cooling jacket/barrel extension much like the South African BXP. It was developed by Major Luis Ricardo Dávila, of the [[Argentine Air Force]], and protected by national Patent n° 220494/5/6/7 on 20/08/1980. It uses 9mm rounds for easy transportation and can be operated in either hand.<ref name=armas>ARMAS Y GEOESTRATEGIA, Vol.2, N° 6, Mayo 1983</ref> A similar earlier Argentine weapon based on the MAC-10 was also designed in 1977 by manufacturer Domingo Matheu, the ''Pistola Ametralladora MPA''.<ref name=armas/><ref>Las Pistolas Ametralladoras Fabricadas en Nuestro País¨, N°172, Enero 2004</ref>
