Caulk gun

A pneumatic caulk gun comprising:

• a body including an inlet, an outlet, and a fluid passage in fluid communication with the outlet, the body configured to support a sealant container adjacent the outlet, a force generated by the pressurized air in the fluid passage configured to be transmitted to a portion of the sealant container, the fluid passage including a port for exhausting pressurized air to an external environment;
• a pump supported on the body, the pump in fluid communication with the inlet and configured to drive pressurized air through the fluid passage;
• and
• an electric motor supported by the body and configured to drive the pump, the motor having a shaft axis oriented orthogonal with respect to the outlet such that a small dimension of the motor extends along a width of the body.

A pneumatic caulk gun comprising:

• a body including an inlet and an outlet, the body configured to support a sealant container adjacent the outlet;
• a fluid passage disposed within the body, the fluid passage in fluid communication with the outlet such that pressurized air in the fluid passage is capable of exerting a force on the container of sealant, the fluid passage including a port for exhausting pressurized air to an external environment;
• a pump supported on the body, the pump in fluid communication with the inlet and configured to drive pressurized air through the fluid passage;
• and
• a pressure release mechanism supported for movement within the fluid passage for selectively blocking air flow through the port.
