I don't quite understand the function of "capacity" for melee weapons as listed in Arsenal's compilation list. I first thought it was for incorporating gear into armor suits, but when I saw melee items listing "-half" and "+2" I became confused. Could someone please give me clue?

Typo. It's supposed to be AP.

there are some limited modification possible (f.E. personalized Grip or Pimped Weapon )
If that is what you're asking for(I don't quite get the 1/2 or +2 ??)
