Chicago Pneumatic Caulking Gun, Cp9885

Will a small 2 gallon Craftsman evolve work?

Can this be used with sausage tube caulking, is there an end piece nozzle available?......works great with regular tubes

How heavy is this? What is the weight?

Has anybody used this for driveway / concrete joint caulking? I don't want to spend $1500 to have some idiot do it for me. I'd rather be that idiot.
