An improved caulking gun is disclosed. The gun includes a cartridge frame having proximal and distal ends and an extension releasably coupled to the proximal end of the cartridge frame. A telescoping shaft is rotatably mounted with in the extension. A spindle is formed on an end of the telescoping shaft projecting from an end of the extension. A portion of the telescoping shaft is threaded and passes through a threaded sleeve mounted at a distal end of the extension. Rotation of the telescoping shaft causes the telescoping shaft to increase and decrease in length causing the distal portion of the telescoping shaft to move between a retracted position adjacent the proximal end of the cartridge frame and an extended position adjacent the distal end of the cartridge frame. A plunger is releasably mounted to the distal end of the telescoping shaft. |
