Anyone know if an XD9 can be converted to a .40 by swapping barrels? Or does it require a slide, too?

The case of the 9mm is smaller than the case of the .40, so you can not convert a 9mm to a .40 in general unless the slide has a removable breech face. You could put a XD .40 slide on a 9mm frame.

I  figured as much, but since you can convert a .40 to 9mm I was hoping the extractor on the 9mm had enough throw to grab a .40 rim.

Yea what he said^^^^^^. This is why you can drop a 9mm conversion barrel into an XD40 with 9mm mags and shoot it just fine but not the other way around. You would save more money selling or trading your XD9 for an XD40 and buying a $115 conversion barrel. Then you could shoot 9mm or .40

Do those conversion barrels just drop in and work just as reliably as if it were actually a 9mm, or does it take some tweaking?

MIne did. EKG Fire dragon 40 to 9mm.

Surprised the hell outta me,I expected it to need some break in,but it has ran 100% straight out of the box.
