On a firearm or other tool, the pistol grip is that portion of the mechanism that is held by the hand and orients the hand in a forward, vertical orientation, similar to the position one would take with a conventional pistol. Tools with pistol grips run the range from hand saws to pneumatic nailers. Often the word "gun" appears in the name of pistol-gripped tools such as the glue gun, caulking gun and nail gun. A number of tools, like firearms, have a forward pistol grip. Drills and grinders often include this feature for added control.
