Title: Worth every penny.
Review: This gun is simple in its design, rugged in its construction and works like a charm. I added a pressure control valve before the hose connection so that pressure could be adjusted for the viscosity of the material at the gun. There is little adjustment to the flow from the trigger - its either on or off, but when you release the trigger the flow stops dead. We are caulking the intentionally created 1/8" space between wood casings and clad windows on a large house and the gun works perfectly - producing a continuous even bead of Alex caulking at about 20 lbs of pressure.Albion 360-1 Air-Powered Standard Line - 1/10 Gallon Cartridge Air Gun
