Editing MAC-10 (section)

==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>
