Why not just file the bulged part down, and remove the slide?
And sometimes people think of a simpler method
Driving the slide forward over the bulge will almost certainly damage the slide. The most likely damage would be to the barrel hole in the slide muzzle.
That hole will probably be expanded and would then be a very loose fit on a replacement barrel.
And as above, you can't drive the barrel out with the slide on the frame because of the barrel retention pin.
And last, remember what I said about NOT trying to drive the barrel out, or risk probable damage to the barrel ring on the frame. The barrel ring is thin metal and easy to distort.
Last, again, your best option is to send it in to the maker for repairs.
