There is one other trick to try before getting drastic. Mount it in a vise, with a wrench on it. Then, you need to heat the frame, while cooling the barrel. To cool it, you need a small bottle of CO2, and a hose with something to direct it into the chamber of the barrel, like a small piece of aluminum or copper tubing, bent and inserted into the hose end. After the frame is heated, crack open the valve on the CO2, and let a small stream flow through the barrel, from the chamber, which will chill it and shrink it. Next, try to torque the barrel off.
