I've got the XD-40 service and picked up an EFK Firedragon 9mm conversion barrel for it. I've put over 300 rounds through it now with no problems. The barrel came with instructions to adjust/tweek the fit to slide if need be. Mine was just fine. The finish looks great as well.
I have read before you may have to adjust the feed lips on the .40/.357 mags to get it to feed the last round. Out of my 6 mags, none have needed it.
I have my Laserlyte QD sighted in for the .40 barrel and the point of aim is the same at 30 feet with the 9mm barrel.
I'm very pleased with it - only problem is the same as with my .40 barrel - too much fun to shoot!!!
