-10 firing speed +10 bonus damage -15 max primary ammo on wearer

I have a strange idea and Valve won't make it,but I don't know a good way to put a new minigun into the game:

• Mini-crit at airborne targets.
  
• -25% primary ammo on weaver

Or I can share two previous minigun ideas(with my own given names):
Last Stand Star(or Last Stand Gun)

• +100% hitpoints
  
• immune to backstabs
  
• no healing from medic,medipacks,sandviches and dispensers(healing from resupply lockers only)

Guevara's Guerilla Gun

• +20% damage resistance on weaver
  
• -25% primary ammo
  
• -10% movement speed
  
• optional: -50% medic healing rate on weaver

Looking at the size of this thing, it could be a mix between the tomislav and the GORU but with buffs and debuffs here and there.
Perhaps something like as follows:

+20% Barrel spinup
-10% Max ammo
+10% Speedon wearer
-10% damage resistance to all types of damage (Cmon, it provides barely any cover.)

Same stats as Tomislav. BOOM! I AM A STAT MACHINE!

+10 damage
-20 health
-35 ammo
+32 clip size
Marked for death
Idk maybe to much

+20% More Damage
+12,5% Clip Size
-15% Less Health
-40% Walking Speed
-10% Damage Taken From Flames & Projectiles

Originally posted by stripper heavy is back:

The heavy doesn't have clips in the minigun so wouldn't -35 ammo and + 32 clip size conflict each other?

+10% damage
+20% movement speen
-20% spinup speed
-20% heal rate
no random critical hits

-10 firing speed +10 bonus damage -15 max primary ammo on wearer

Pro :
+10% Firing Speed.
+20 Movement Speed.
+100 Ammo
Con :
-25% Accuracy
-33% In a clip
-10 Slower Reload
---------------------------------
My Idea was that It used Clips instead of having it all be able to fire at once.
( I dunno why, just did.)

+30% Firing speed
-20% Spinup time
+10% movement speed while deployed
-20% Damage
Increase in push force taken from airblasts and explosions

well this looks like a nice heavy primary

+ Knock back on the target for every single burst shot.

- -20 damage

+20%firing speed
-10% damage (in air)
+5% damage(on stand)
+15-20% move speed
ammo clip only for 75-80 ammo (heavy have 3 ammo clips)
-15%healt
no spin up time
mini-crits

+20% firing speed
+20% mobility while deployed (still is slower than regularly walking, but faster than other miniguns)

-15% damage taken while deployed
-15% damage

could just be a reskin of tomislav
