1. A spray gun configured to receive flows of a fluid and of air and to emit a fluid spray and the air, the spray gun comprising:
a gun body having a first bore, a second bore, and a gap disposed between the first bore and the second bore, the first bore and the second bore disposed coaxially on an axis;
a spray fluid control cartridge having a first housing disposed within the first bore, wherein a spray fluid control valve is fully contained within the first housing and is configured to control spraying of spray fluid from the spray gun, wherein a fluid valve member of the spray fluid control valve extends out of the first housing and towards the second bore;
an air control cartridge having a second housing disposed within the second bore, wherein a first valve member is at least partially contained within the second housing, the first valve member configured to control airflow for spraying by the spray gun, wherein a receiving chamber is formed in the first valve member; and
a trigger extending into the gap and configured to actuate the spray fluid control valve between a closed state and an open state;
wherein a valve stem of the fluid valve member extends into the receiving chamber of the first valve member such that a projection extending radially from the valve stem of the fluid valve member is disposed within the receiving chamber;
wherein the projection is spaced from an opening of the receiving chamber by a first axial gap, the valve stem of the fluid valve member extending into the receiving chamber through the opening; and
wherein the trigger is configured to engage the first valve member to shift the first valve member to a first air valve open state prior to engaging the projection to exert a driving force on the projection of the valve stem of the fluid valve member to shift the spray fluid control valve to the open state.
