Many map areas have lighting that grenades and general combat can destroy, and as you plow through more waves, illumination becomes a factor in firefights. For this reason, I wouldn’t recommend selling the Medic’s starter pistol-it’s only worth $100, and the extra two shots of healing it grants can be handy. Unequipped weapons recharge in the background. In big fights, rapidly swap between these guns to heal teammates as quickly as possible. Every Medic weapon has an individual, rechargeable “battery” for its healing dart ability.
