ABSTRACT:
A caulking gun includes an easily repositionable handle for better ergonomic balance. The handle, able to slide along the length of the gun below the cartridge holder, is engaged and disengaged using the trigger. The handle disengages from the cartridge holder when the trigger is cocked upwards, and then relocks on the cartridge holder when the trigger is squeezed. A nozzle cutter is positioned away from the action of the trigger and handle and a retractable, adjustable arm clip provides a positive secure secondary connection with the user. A trigger bar connects the trigger to an actuator plate, is aligned with a restraining plate and set to engage and disengage with the plunger advancing mechanism such that the plunger shaft slides rearward slightly relieving a cartridge's internal pressure each time the trigger is released.
