Query: Caulk Gun Works Well

I have used this caulk gun to apply PL siding caulk. This is fairly stiff caulk but the gun handled it well after adjusting the compressor's regulator to 40 PSI. My little Porter-Cable pancake compressor is easily able to keep up with the gun. The gun did leak where the barrel attaches to the handle but this was easily overcome by adding duct tape to provide a seal. The trigger leaks slightly when depressed but not to the extent that the performance of the gun is decreased. The trigger has a ridge for you finger but it actually causes your finger to rub on the barrel when depressed. Moving your finger below the ridge solves the problem. Overall the gun works well and considering the cost, it works excellent.
