ABSTRACT:
A caulk gun has a cartridge-carrying body with a fixed handle and a pivoting handle depending therefrom, the pivoting handle being coupled to a plunger for axial movement thereof to dispense material from the cartridge in response to movement of the pivoting handle toward the fixed handle. The pivoting handle has a proximal end portion which diverges from the fixed handle to an index finger engaging portion and a distal end portion which is curved toward the fixed handle in the normal rest configuration of the gun, such that the pivoting handle, at both its distal end portion and its index finger engaging portion is spaced from the fixed handle generally the same distance. The fixed handle has a widened portion intermediate the ends thereof.
