If you take a semi-auto with 5" barrel, compare it to a revolver with 5" barrel, the revolver is always about 1.5" longer.
The barrel length for a semi-auto is measured from muzzle to breech. A revolver barrel length is NOT measured from muzzle to breech but from...well...simply one end to the other without including the cylinder.
Since the law of 104mm barrel length is to prevent handguns from being easy to conceal, it should only be able to roughly regulate the size of a handgun without prejudice. But revolvers just always have to be longer.
