and here it says the pistol barrel must be rifled for the .410:

Interesting to note that the barrel in question is termed a ".45/.410." The
one I shot was chambered only for .410, was rifled, but the lands took
imagination to see. Perhaps the company has had to alter that barrel to
remain on this side of the law.
