And I have numerous guns which are "native" .40 caliber but I shoot 9mm through them using a conversion barrel. In some cases, I can shoot 9mm and .40 out of the .40 mags with no mods and in some cases I can shoot 9mm and .40 from the .40 mags only after I tweak them.
There is no law anywhere saying this is illegal to do.
