Fluid spray gun trigger mounting and retention

A spray gun comprising:

• a gun body;
• a gun bore extending within the gun body, the gun bore extending along a spray axis;
• a body bore extending through the gun body and along a mount axis;
• a first valve assembly at least partially disposed within the bore, the first valve assembly including a first valve configured to control emission of spray fluid from the spray gun;
• a trigger mountable to the gun body, the trigger configured to actuate the first valve from a closed state to an open state, wherein the trigger is movable relative to the gun body between an engaged state, in which the trigger is movable to open the first valve, and a disengaged state, in which the trigger is spaced from the first valve assembly such that the first valve assembly can pass axially by the trigger along the spray axis;
• and
• a trigger mount configured to mount the trigger to the gun body, the trigger mount actuatable between a retaining state, in which the trigger mount connects the trigger to the gun body and holds the trigger in the engaged state, and a mounting state, in which the trigger is dismountable from the trigger mount and gun body, the trigger mount comprising:
• a mount body at least partially disposed within the body bore and movable relative to the gun body, the mount body configured to displace in a single direction along the mount axis to disengage from a first trigger arm of the trigger and a second trigger arm of the trigger and actuate the trigger mount from the retaining state to the mounting state.

A method of assembling a spray gun, the method comprising:

• displacing a mount body of a trigger mount in a first direction along a mount axis of a body bore formed in a gun body of the spray gun;
• passing a trigger by the mount body such that a first pivot head of the mount body is aligned with a first mount opening through a first arm of the trigger and such that a second pivot head of the mount body is aligned with a second mount opening through a second arm of the trigger;
• and
• displacing the mount body in a second direction along the mount axis such that the first pivot head enters into the first mount opening and such that the second pivot head enters into the second mount opening.
