Pistol type grease gun, a one-hand grease gun for lubricating grease nipples on vehicles, bicycles and machinery. The trigger-style lever sits under the head like a pistol grip, so the gun is held and pumped with a single hand. It has a black ribbed barrel, a silver metal head with a curved trigger lever, and a rigid delivery pipe ending in a nozzle coupler. A triangular pull handle at the rear end of the barrel works the plunger rod.
