A grease gun comprising:
- a body having a reservoir connection aperture including an inner portion, an outer portion and a plurality of concentric grooves disposed to receive a retention fastener positioned along the inner portion;
- a grease reservoir in communication with the reservoir connection aperture, the grease reservoir having a groove in a portion of an outside surface of the grease reservoir;
- and
- the retention fastener removably received by first and second concentric grooves, the retention fastener in operational engagement with the first groove to engage and disengage the grease reservoir and in operational engagement with the second groove to removably retain the grease reservoir in the grease gun.
A method of mounting a barrel to a grease gun comprising:
- inserting the barrel into a barrel mount in a grease gun body;
- aligning a groove on the barrel with a snap ring having a user operable engagement assembly and movably retained within first and second concentric grooves in the barrel mount;
- engaging the snap ring with the groove on the barrel and the first concentric groove during insertion of the barrel;
- and
