Abstract: A caulking gun includes a cartridge holder, a stock, a plunger, actuator plates, an actuator spring, an adjustable handle, a trigger, a nozzle cutter, a cartridge poker and a retractable arm clip. A handle, able to slide along a lower rail of a cartridge holder, is engaged and disengaged using a trigger. Said handle permits a user to adjust the balance point of the gun at will. To disengage the handle, a trigger is lifted, releasing a forked tab at the rear of the handle that engages the lower rail. Squeezing the trigger reengages the forked tab. The actuator plates are aligned such that a cartridge's internal pressure is relieved each time the trigger is released. A nozzle cutter provides a clean cut, and allows for nozzle tips to be easily discarded. A retractable arm clip is used as a secondary contact point with a user's arm.
