I was 2 hrs. messing with my Lucas grease gun again today. I tried to reload it, I couldn't pull the rod back, half the grease was behind the plunger all gob up on the spring, what a mess. I clean what I could with my hands, able to put some in a can. I'd like to once find a grease gun that will work right, one time every time, its bad enough that a lot the grease doesn't get in the fitting, instead gets all through the plunger and spring, then its all over me and work bench, tied of wasting grease, and shop towels.
My grease gun is a lever type, its what I've always used. I see a lot of people like the pistol stile grease gun, seams like they'd be hard to operate with one hand. The lever style, I can grip it with 2 hands and force the grease in the fitting, if and when once in a blue moon the gun works right.
