I believe the newer ones take spyer threaded barrels? I'd say pick up a barrel with a tighter bore and you'd be good to go. Impossible to break, will never let you down... (Well, nothing a few drops of oil and a hammer won't fix.)
Yes, the Inferno takes spyder threaded barrels, and those are everywhere and inexpensive. You don't need a hammer to fix an Inferno - You can use another Inferno to beat it into shape.
