Actually what you are saying is not quite correct. Of course they are not pipe threads, but there will still be some constriction. Back in my silhouette days, I saw a lot of Dan Wessons with constricted bores on both ends of the barrel, at the frame and at the barrel nut. A lot of people attempted to deal with this by lapping. The constriction is not a lot, but it is there. It can be felt when pushing a soft lead slug through the bore.
