I know a couple guys that shoot IDPA and they all use frangible when shooting steel. There are several of them that cast and load their own 9mm in bulk but even they use factory frangible rounds. I've never asked but I would wager that they can't find frangible 9mm bullets for reloading anywhere since I'm sure if they could, they would.
If you had a large enough order you may be able to get someone to bring them in for you from the US. Mystic Precision maybe?
I know General Dynamics (IVI factory) make them but, alas, no retail sales from them. I've found a dozen or so loaded frangible 9mm with IVI headstamps in the gravel (discarded/dropped) from when the military shoot steel at the range I'm a member at.
