A dispensing gun assembly includes a frame, a rod, a piston, a driver, a trigger, and a linkage. The rod slideably connects with the frame for linear movement with respect to the frame. The piston connects with the rod for movement with the rod. The driver selectively engages with the rod to move the rod in a linear direction when engaged with the rod. The trigger slideably connects with the frame. The linkage connects the trigger with the driver such that linear movement of the trigger with respect to the frame in a rearward direction results in the driver engaging the rod and linear movement of the rod and the piston in a forward direction.

1. A dispensing gun assembly comprising: a frame;a rod slidably connected with the frame for linear movement with respect to the frame;a piston connected with the rod for movement with the rod;a driver including a rod opening receiving the rod, the driver selectively engageable with the rod to move the rod within the rod opening in a linear direction when engaged with the rod;a trigger slidably connected with the frame;a fixed handle fixedly connected with the frame, the trigger is disposed forward from the fixed handle and is slidable with respect to the frame between an unsqueezed position and a fully-squeezed position; anda linkage connecting the trigger with the driver such that linear movement of the trigger in a rearward direction toward the fully-squeezed position results in the driver engaging the rod and linear movement of the rod and the piston in a forward direction,wherein the frame defines a track and the trigger includes a slide received in the track and a grip extending downwardly from the slide, the grip movable with the trigger such that linear movement of the grip results in movement of the slide in the track, wherein the slide includes an aperture and the rod is received in and extends through the aperture such that the rod is also received in the slide. 2. The dispensing gun assembly of claim 1, further comprising a spring acting against the driver, wherein the spring biases the driver toward an at-rest position, and the trigger is in the unsqueezed position when the driver is in the at-rest position. 3. The dispensing gun assembly of claim 1, further wherein the fixed handle is positioned rearward of the grip, wherein the grip and the fixed handle are configured to be squeezed to move the grip with respect to the fixed handle. 4. The dispensing gun assembly of claim 1, wherein the linkage includes a link pivotally connected with the driver such that the link pivots about a first pivot axis with respect to the driver and the first pivot axis moves in a linear direction as the link pivots with respect to the driver. 5. The dispensing gun assembly of claim 4, wherein the link pivotally connects with the frame such that the link pivots about a second pivot axis with respect to the frame. 6. The dispensing gun assembly of claim 5, wherein the link pivotally connects with the trigger such that the link pivots about a third pivot axis with respect to the trigger and the third pivot axis moves in a linear direction as the link pivots with respect to the trigger. 7. The dispensing assembly of claim 6, wherein a first distance, which is measured between the first pivot axis and the second pivot axis, is less than a second distance, which is measured between the second pivot axis and the third pivot axis. 8. The dispensing assembly of claim 6, wherein the linkage further includes a driver axle connecting the driver with the link and a trigger axle connecting the trigger with the link, wherein the link includes an upper oblong hole that receives the driver axle and a lower oblong hole that receives the trigger axle. 9. The dispensing assembly of claim 8, wherein the frame includes an axle post and the link includes a central hole that receives the axle post. 10. The dispensing gun assembly of claim 1, wherein the linkage includes a rack and pinion arrangement connecting the trigger with the driver. 11. The dispensing gun assembly of claim 1, further comprising a driver axle and a trigger axle, wherein the linkage includes a link having an upper oblong hole that receives the driver axle and a lower oblong hole that receives the trigger axle. 12. The dispensing gun assembly of claim 11, wherein the link pivots with respect to the frame about an axis disposed between the upper oblong hole and the lower oblong hole. 13. The dispensing gun assembly of claim 12, wherein the frame includes an axle post and the link includes a central hole that receives the axle post. 14. A dispensing gun comprising: a tube for containing a material that is to be dispensed; andthe dispensing gun assembly of claim 1, wherein the piston is received in the tube. 15. The dispensing gun assembly of claim 2, wherein the spring is a second spring and further including a first spring acting against the driver, each of the first and second springs receiving the rod. 16. The dispensing gun assembly of claim 15, wherein the first spring acts against a rear section of the frame and a rear surface of the driver and urges the driver toward a position where the driver does not engage the rod, which allows the rod to move within the rod opening. 17. The dispensing gun assembly of claim 16, wherein in a squeezed position of the trigger the second spring is compressed and the driver pivots so as to engage the rod and drive the rod in the linear direction, and wherein in the unsqueezed position of the trigger the second spring pivots the driver away from the rod allowing the driver to move with respect to the rod towards its at-rest position.
