question about the weapon and equipment upgrades

when I upgrade certain weapon or equip will I lose contract points, or its the number of points I need to have so I can upgrade it, I havent play the game long time and everything is messed up now for me so any help will be good, tnx

Contract points, or loyalty vouchers as they are called, are only used for upgrading weapons/modules from Mk 2 to Mk 3 quality. Of course they are consumed to the amount specified.
