A sealant gun is disclosed having a pair of spaced longitudinally extending support arms connecting a stock portion to an apertured distal end portion, the distal end portion having a generally rectangular outer surface profile. The sealant gun is provided with a handle and an actuation mechanism for driving a piston incrementally in the longitudinal direction of the arms. A locking mechanism is also provided to selectively prevent or permit the piston to be retracted in the longitudinal direction. The generally rectangular outer surface profile of the distal end of the sealant gun enables groups of such sealant guns to be conveniently stacked or hung on a display rack.
