create alias mac-10 -> mac-10/11
create alias mac-11 -> mac-10/11
There are no significant visual distinction between both, other than minor size difference and different calibers (9mm /.45 ACP vs. .380 ACP) of both machine pistols. Users cannot tell apart which one is MAC-10 or MAC-11 at a glance without any given context via explanation on the illustration or artist commentary.
Even the IMFDb classify the latter, smaller variant under same MAC-10 article. While tagging should maintain accuracy as much as possible while reducing tag count bloat, the suggested alias will still be applicable to any Ingram MAC variants.
See this image as reference. Nothing is significantly different from each models.
Unlike the distinguishable difference between the full-sized IMI Uzi (triangular stock, handguard), smaller Mini Uzi (wire stock, narrower handguard) and smallest Micro Uzi (pistol-like, no handguard).
