To the best of my knowledge, you don't have to modify the slide at all to fit the barrel. The barrel, OTOH, must have the OD near the muzzle to give a tight fit. The rear of the barrel, from about an inch back, should be tapered, or at least relieved, to prevent barrel spring, and to ensure functioning and cycling.
In my experience, I can gain the same benefits (reduced recoil and improved accuracy) by installing a heavier spring (18 lb. range) and a Briley spherical bushing, on a match grade barrel.
