Review on Dripless SH200 Contractor Professional Open Frame by Devin Jenkins

Best Caulking Gun I've Ever Used. It's worth every penny I paid. The thickness of the steel frame is about 2mm. The whole weapon is solid and doesn't feel wobbly. The trigger applies constant pressure, creating a steady and even flow from the nozzle. The spring mechanism releases pressure as soon as you let go of the trigger. Promised "Dripless" as branded. The cutter hides in a hole above the trigger. It's sharp and safe as well as comfortable. To release the hex bar, simply grasp the frame and gently pull the hook back. You don't need a trigger to unlock the lock on the stem.
