Last I checked, you could mostly find references to ECM in reference to the FGC-9. I played with when it was first published, and successfully made a rifled barrel blank. I’ll probably do it again at some point, to comply with the NFA for some other projects I have in my backlog - smoothbore pistols are considered “Any Other Weapons”, but even rudimentary rifling is enough to make it “just a pistol”.
