Er. I think I can make out what you're trying to say. I have to say your typing is difficult to read.
Real life definitions of "LMG", "MMG", and "HMG" are actually not clearly established. Different countries and different manufacturers have different takes on what classification any given machinegun is. Some don't even use the terms "light", "medium", or "heavy", preferring other nomenclature like "general purpose".
However, Shadowrun DOES have specific ideas on how it classifies machineguns. And that is largely by how much damage each one does, not by their weight or ease of carrying.
There is a little fuzziness between guns, but most of the LMGs do 6P damage, the same as assault rifles, most MMGs do 6P to 7P damage, about what battle rifles do, and HMGs do 7P to 9P damage, about the same as sniper rifles to the heavy "anti-material" class rifles.
Shadowrun does not use calibers, mostly, but if we are classifying machineguns by damage code, the equivalent real-life weapon "light" seems to be about equivalent to 5.56x45 or similar, "medium" is probably 7.62×51, and "heavy" is probably 12.7×99 (.50 cal) up to 20mm calibers.
The non-minigun real life equivalent of the Shadowrun LMG is the M246 SAW. MMGs are likely the M-60 or similar. HMG is the old .50 caliber Ma Deuce.
Shadowrun calls the Vindicator a Light Machine Gun. It is modeled after the real-life
XM-214 Six-Pak "microgun" developed by General Electric. The XM-214 fires a 5.56x45mm round.
Which, hey, is more or less the same size ammo fired by the
M16 assault rifle.
If we were to stat out the
M134 Minigun, it would probably be classified as a MMG under Shadowrun standards.
